The Canon EF-S 17-55mm f/ IS USM Lens, with a fast, fixed f/ aperture, very high image quality, 3-stop Image Stabilization and a very popular focal length range, is one of the best general purpose lenses available. Since EF-S lenses only mount on Canon EF-S bodies - which all feature a FOVCF - the 17-55mm focal length range always equates to the field of view of a lens mounted on a full-frame Digital SLR. This range covers what I consider to be the most important focal lengths for a Canon general purpose lens. This is a focal length range that can be used for everything from a wide scenic landscape to a relatively-close portrait. Canon already had these focal lengths similarly covered in their econo kit lens - the Canon EF-S 18-55mm f/ Lens. Reality is that these are vastly different lenses - in build, optical and feature qualities - and price. The kit lens is a good value for the money, but does not compare with the 17-55 IS. Canon already had a superset of the 17-55mm focal length range covered with the Canon EF-S 17-85mm f/ IS USM Lens. The EF-S 17-85 IS has a higher build quality, image quality and feature set than the EF-S 18-55 - adding Ring USM and 3 stop image stabilization to the feature set. What the 17-55 IS adds to the 17-85's feature set is a fixed f/ aperture and L-Series grade UD Ultra-Low Dispersion glass lens elements. Of course, price, size, weight and a reduced focal length range are the downsides of the 17-55 compared to the 17-85. Positioned above from left to right in their fully retracted positions are the following lenses Canon EF-S 18-55mm f/ IS II Lens Canon EF-S 15-85mm f/ IS USM Lens Canon EF-S 10-22mm f/ USM Lens Canon EF-S 18-135mm f/ IS Lens Canon EF-S 18-200mm f/ IS Lens Canon EF-S 55-250mm f/ IS Lens Canon EF-S 17-55mm f/ IS USM Lens The same lenses are shown below in their fully extended states with their lens hoods in place. With a fixed fast f/ aperture meaning the widest aperture opening is f/ through the entire focal length range - f/22 is the narrowest setting, exposure settings do not change when zooming in on a subject. To some, this is not a big deal - to me, this is a great feature. F/ is as fast as any Canon zoom lens currently made. It is fast enough to stop action in many indoor venues higher ISO settings typically required - fast action indoor sports may require f/2 or wider. This wide aperture also activates the higher autofocus sensitivity mode for certain focus points in many Canon bodies f/ does not have to be selected to get the benefit of this feature. F/ also presents a bright viewfinder to the user. Wide open, the 17-55 is able to produce a nicely blurred background. By employing a circular 7-blade aperture barrel, the Canon 17-55mm Lens produces a decent quality background blur even when stopped down. With a focal length range that is composed of relatively wide focal lengths, this lens needs a close subject to create a diffusely blurred background. Combining an f/ aperture with the 3 stop image stabilization, the Canon EF-S 17-55mm f/ IS USM Lens is arguably the most handholdable lens Canon currently makes. Image stabilization will allow a shot to be taken at a shutter speed up to 3 stops slower than without IS. Sorry, but IS will not stop subject motion. This IS version is tripod sensing to prevent feedback loops between the IS sensor and stabilizer motor vibrations. The manual recommends turning IS off when tripod-mounting the lens to save battery life or when panning panning mode IS is not available. Leave IS on when handholding or shooting from a monopod. The IS implementation on this lens is very well behaved - it is quiet and does not cause the image to jump when starting up. The three lenses compared above are from left to right, the Canon EF-S 17-55mm f/ IS USM Lens, Canon EF-S 17-85mm f/ IS USM Lens and Canon EF-S 18-55mm f/ IS Lens. All lenses are shown extended to their maximum lengths with their optional lens hoods attached. With Ring USM Ultrasonic Motor, the 17-55 IS focuses very quietly and very fast. Focus accuracy has been very good for me an even more important fact. Note that, while I did not notice an issue, some are reporting AF accuracy inconsistencies at infinity focus distance. FTM Full Time Manual focusing is a very nice feature of this lens. The focus ring is rather small, but turns easily. Likely to get far more use is the zoom ring - it is very nicely sized and turns smoothly with little effort. The AF and IS switches are recessed to prevent accidental changes. Canon claims that "By optimising Super Spectra lens coatings and lens element shaping, Canon’s engineers have been effective in suppressing flare and ghosting ­ more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural colour balance." In reality, I am finding the 17-55 IS to be quite flare-prone if the sun or bright light is in the frame. Otherwise, color and contrast are excellent. Prior to receiving my 17-55 IS, I stated that I expected its image quality to match or nearly match that of Canon's L Series Lenses as it shares the L-Series UD lens elements. As it turns out, my 17-55 matches or exceeds the optical performance of my L-Series zooms in this similar focal length range ... This lens is sharp! Wide open and from edge to edge. Unless the distance is close that is - I'm finding that close subjects do not produce the same image sharpness as normal distance subjects. The ISO 12233 chart test results indicate this as well. The 17-55 IS shows slight sharpness improvement at f/4, but performance at f/ is very good. My Canon EF 16-35mm f/ USM Lens is slightly sharper in the center at 17mm wide open, but the 17-55 IS is sharper at all other tested focal lengths - and proved much sharper in the corners at all focal lengths and apertures. Distortion was also less on the 17-55. In my opinion, the only reasons to buy the 16-35 over the 17-55 are for full-frame compatibility a big reason, better build quality and environmental sealing EF-S compatible bodies are not weather sealed at this time. Similar story with the Canon EF 17-40mm f/4L USM Lens. The 17-55 IS is sharper at all other tested focal lengths - and proved much sharper in the corners at all focal lengths and apertures. At close distances, the 17-40 had sharper corners and held its sharpness to a narrower focal length than the 17-55. Lower barrel distortion at the wide end is also in the 17-55's favor. Full-frame compatibility, better build quality and environmental sealing are in the 17-40 L's favor. I suspect the wider price discrepancy between these two lenses will keep sales of the 17-40 L going stronger than for the 16-35. The Canon EF-S 17-85mm f/ IS USM Lens boasts a longer focal length range but lacks the fast aperture and is not as sharp especially in the corners as the 17-55 IS. The two lenses are rather close in center sharpness but most of the time my primary subject is not dead center in the frame. Once again, lower barrel distortion at the wide end is in the 17-55's favor. Price is also a differentiator between these lenses. The similarly-built Canon EF-S 10-22mm f/ USM Lens turned in similar optical results to the 17-55 IS in the short range of focal lengths that overlap. I see these lenses more as complementary than competing. At all overlapping focal lengths and apertures, the 17-55 is sharper than my Canon EF 24-70mm f/ USM Lens. The default image below is a 100% crop from the 17-55 IS at 55mm, f/ Mousing over the image will show a crop from the Canon EF-S 18-55mm f/ IS Lens at f/ wide open. Keep in mind that the 18-55 IS should have a DOF advantage, but you will see the 17-55 IS still performing better in the foreground and background. Also, the vehicle grill is the center of the frame - where the 18-55 IS competes best. However, this focal length is the weakest in the 18-55 IS's range. Some additional information about the above comparison ... This comparison was shot with a Canon EOS 40D. There was a 250-pixel-wide swath removed from the image as indicated by the white line. This allows a foreground object and some background to be present in the image to confirm focus accuracy. Images were shot as RAW and processed with the Neutral Picture Style 0 Contrast and sharpening = 1 very low - 2 would look noticeably sharper. Images were converted in DPP to 16-bit TIFF files, cropped in Photoshop and saved as 80 quality JPG files. The lighting was harsh mid-day sunlight on a clear day. A tripod was used - the shutter speed was 1/2000 for the f/ shot 1/500 for the f/ shot. In addition to being sharp, CA Chromatic Aberrations are very well controlled in the 17-55 IS. The following example is meant to show the difference in CA between an economy lens 18-55 IS again and a top quality zoom. This one was shot at 17mm/18mm and at f/ for both lenses. This 100% crop sample is located about 25% into the frame from the top left corner. Mousing over the image will show the 17-55mm IS advantage. Distortion is present over most of the 17-55mm focal length range. Mild barrel distortion is present until about 24mm where pincushion distortion becomes present through 55mm. Your spouse will appreciate how the 17-55 makes them look thinner at the longer focal lengths use this excuse if you need help getting spousal purchase permission. Being a wide aperture, wide angle lens, expect to see some vignetting from the 17-55 IS. The amount of vignetting is less than I anticipated - basically visible only in the corners at f/ when photographing an even-colored subject such as a blue sky. One of the benefits of using an EF lens on a body is that much of the lens vignetting is not apparent within the cropped field of view. Click on the image below to compare the Canon EF-S 17-55mm f/ IS USM Lens to other lens models with and without hoods opens in new window to save your place in this review. The 17-55 passes distance information to the camera body for use in E-TTL II exposure determination. Most new Canon lenses have included this feature. The Canon EF-S 17-55mm f/ IS USM Lens is a middle weight at oz 645g. At x x the 17-55mm IS becomes the largest EF-S lens to date. It is, however, a very nice size/weight to carry around and balances well on compatible camera bodies. To put size into perspective, the above size comparison photo includes from left to right the Canon EF 17-40mm f/4L USM Lens, Canon EF 24-105mm f/4L IS USM Lens, Canon EF-S 17-55mm f/ IS USM Lens and Canon EF 24-70mm f/ USM Lens. The same lenses are show fully extended below. Similar to many of the L-Series zooms, the 17-55 IS features a 77mm filter thread. A feature appreciated by circular polarizer filter users is the non-rotating front element does not rotate with focusing or focal length change. The 17-55 extends with focal length increase, but does not extend with focusing. With a relatively-long-for-its-focal-length-range closest focusing distance of the 17-55 IS yields a meager maximum magnification of at 55mm. As usual, extension tubes can increase the magnification ability significantly. With the Canon EF 12mm Extension Tube II, magnification is With the Canon EF 25mm Extension Tube II, magnification is Canon's spec. As this is an EF-S lens, version II of Canon's Extension Tubes are required. The 17-55 is not compatible with Canon's Extenders. The 17-55 IS shares design and build qualities with Canon's other recently-released EF-S Lenses - especially the Canon EF-S 10-22mm f/ USM Lens. It is nicely designed and well thought out, though I don't prefer the rear-positioning of the manual focus ring that is where I generally grip the lens. The 17-55 IS is not as elegant in design and function as the L-Series zooms, but it is very good in this regard. Not real important but missing is the Canon date code. I'm not sure why Canon did not go all the way and make the 17-55 IS an L-Series lens. An upgraded metal lens barrel seems to be the missing component - and the red ring. Also, the accessories included with L-Series lenses are missing - the Lens Pouch LP1219 and 17-55 IS-exclusive Lens Hood EW-83J are optional. Since Canon has an L-Series lens on the PowerShot Pro 1, making a non-"EF" L lens is apparently not outside of their definition. This lens certainly has the image quality to be an "L". With the help of a 12mm Extension Tube, you can physically mount this lens on a full frame body. But you probably will not want to. The image above shows the image circle as seen through this combination by a Canon EOS-1Ds Mark III. In addition to the heavy vignetting, AF does not work and the aperture information does not report to the camera. Even in MF mode, more hurdles remain - at 55mm, the 17-55 will not focus any farther away than about 7" or so in front of the lens. This distance rapidly decreases as the focal length is widened until the subject is against the glass and beyond this point no subject can be in-focus. It was a fun exercise at least - and now we know. I am getting some email asking about dust issues with this lens. Some are seeing a noticeable amount of dust collect under the front element. Dust seldom makes a noticeable difference in image quality - No one has indicated to me that their dust has affected the image quality of their 17-55. But it is not normal for this amount of dust to accumulate inside the lens. My 17-55 came with one small speck of dust in it a genuine Canon factory dust speck I suppose and has not accumulated any additional dust. I've shot thousands of mostly outdoor pictures with this lens. Weddings, events, parties, family activities, portraits, landscapes, stage shows, car shows, night sky ... there are far more uses for this lens than I am going to think of. Unless there is an upgrade to a or full frame body in your future, the Canon EF-S 17-55mm f/ IS USM Lens is an ideal lens to include in your kit. Even if a larger format sensor body is in your future, the resale value of this lens remains strong. With the introduction of the 17-55 IS, Canon displays its commitment to the EF-S line of lenses. With the huge base of Canon EF-S Digital SLR users, the 17-55 IS, with its excellent features, specs and image quality, will find a home in many professional and amateur photographers' kits.

It is of course the size and weight of this lens that triggers this response. The EF 40 STM enters the world tied with the Canon EF 50mm f/ II Lens for the lightest Canon EOS lens designation. And, being just over half as long as the 50 f/ II, easily shatters the length record. This lens is even shorter than a Canon extender comparison below. But the size of this lens is not the only reason to not take it seriously. The pancake's breakfast-level price ranks it near the bottom of all currently available Canon lenses. You could buy 70 of these for the price of one Canon EF 800mm f/ IS USM Lens. How many 40s would it take to consume the volume of one 800 L is a question I'm still pondering. It is indeed hard to take such a tiny, inexpensive lens seriously, but don't write the EF 40 STM off too quickly. With new acronyms in the model name, let's start this review with some quick definitions. You know what "Canon" means. You know what "Lens" means. 40mm is of course the focal length of the lens. "EF" means that this lens will mount and function properly on all Canon EOS cameras produced to date. The new acronyms are "Pancake" and "STM". "Pancake", in lens speak, refers to a short, flat shape. "STM" stands for "Stepping Motor" - a motor that moves or rotates in small discrete steps more info later in the review. With that understanding, let's move to an important lens decision factor - focal length. When choosing a lens, focal length should be one of your top selection priorities. Falling between the wildly-popular 35mm and 50mm focal lengths, Canon's 40mm focal length choice is an interesting one. While a 40mm lens sounds close to a 50mm lens and the two can often be used interchangeably, there is a difference in the perspective these lenses provide when identical framing is used. In the example below, the sides of the frame are nearly identical for each example focal length, but the large trees in the background change size greatly in proportion to the foreground due to the different focus distances required for the same framing. These examples were shot with a full frame camera. The same lenses used on an APS-C camera would of course frame more narrowly 40mm frames like 64mm on APS-C, but perspective differences would still show in identically framed shots. The wider angle lens will emphasize what is closer to the camera in relation to the background. The wider angle lens will also emphasize human subjects' closest parts - often noses - making them noticeably larger in relation to the rest of bodies if used at a close distance. 40mm is not a good head shot portrait lens. Step back and your subjects will be happier with their portraits. Portraits not framed tightly are but one of a huge range of uses for a 40mm lens. 40mm is a focal length that you could leave mounted for general purpose needs. A downside to using a single focal length for all of your images is that your images can all begin to look similar. My preference is to use a range of prime lenses - in no more than 1/2 or 2x focal length increments. Adding to its multipurpose capabilities is the relatively wide f/ aperture. While not wide for a prime lens in this focal length, f/ is as wide as zoom lenses get. An f/ aperture is usually what I consider minimum for stopping motion indoors. Here is an outdoor motion-stopped example. The sample picture above was captured with the Canon EOS 5D Mark III. Settings were ISO 200, f/ 1/1250, AI Servo AF, Burst Mode, 5300K white balance and the Standard Picture Style. A B+W 52mm XS-Pro Kaeseman Nano Circular Polarizer was utilized for this shot. Not surprising with its small size is that the 40 STM Lens forgoes image stabilization. The relatively wide f/ aperture makes this feature less missed. This lens is handholdable in lower light conditions. Small size and small price are great, but ... image quality is a sacrifice one would expect to make to gain these attributes. Amazingly, this lens delivers impressively in this regard. The Canon EF 40mm f/ STM Lens is very usably sharp at f/ with a modest increase in softness as the outer portion of the image circle is reached. Stopping down to f/4 results in a sharp image across the frame save the extreme full frame corners. At f/ even the extreme full frame corners are very sharp - allowing this lens to compete with lenses at far higher prices. The ISO 12233 chart comparison tool will show you firsthand what these results look like - and will allow comparisons with the rest of Canon's lenses. Find this link at the top of the review. At f/ the EF 40 STM shows about 2 stops of vignetting in full frame corners. This is a noticeable amount, but not a severe or surprising amount. Half of the vignetting is gone at f/4, but .6 or .7 stops remain throughout the balance of the aperture range. As usual, APS-C users will not have to worry about vignetting from this full frame-compatible lens. CA Chromatic Aberration is very well controlled - nearly absent. Same with flare. Even with the sun in the full frame corner, flare is hard to notice. Flare performance is certainly advantaged by the use of only 6 lenses in 4 groups. The 40 STM has very minimal distortion. Utilizing a circular 7 blade aperture, the 40 STM delivers a nice background blur quality as shown below. A 40mm f/ lens is not going to set any background blur records, but when used at f/ and a short focus distance, the background goes nicely out of focus. The site's ISO 12233 chart tool is ideal for directly comparing lenses to each other, but I took a couple of inexpensive and relatively similar lenses outdoors on a clear day for another comparison with the 40 STM. You will likely recognize these images as being the bottom right crop from the perspective comparison shown near the beginning of the review. Compared at the link below click on the image are the Canon EF 35mm f/ Lens, Canon EF 40mm f/ STM Lens and Canon EF 50mm f/ II Lens. Extreme full frame corner crops will show a lens at its worst. The Canon EF 50mm f/ II Lens is very well regarded for the image quality sharpness it delivers for its extreme low price. While it is a bargain, it is extremely low end in all other regards including build quality - which includes a plastic mount. My first 50mm f/ II fell apart. It physically broke in half for no apparent reason. The 50 f/ II compared here was purchased specifically for this review. The replacement lens does not perform as well as my first one did - I do think it is an inferior copy. But, it sure makes the 40 STM look amazing. The build quality difference is also as night and day. The Canon EF 35mm f/ Lens is another inexpensive lens with an even closer-to-40mm focal length. This lens is sharp in the center of the frame, but does not have a flat plane of sharp focus - and corners are especially not rendered well. The 50 f/ II and 35 f/2 both have the wider aperture advantage. The difference between f/2 and f/ is one stop - one stop is a 2x difference in the amount of light delivered to the sensor. If you don't need that extra stop, the 40 STM is, in my opinion, the best option of this group. The 40 f/ STM Lens is the first available Canon lens with the stepping motor AF implementation. The Canon EF-S 18-135mm f/ IS STM Lens was simultaneously announced, but showed up in stock only as I put the finishing touches on this review. While I definitely prefer Ring USM focusing systems better, the STM design works well. It focuses reasonably fast and most importantly, accurately. The STM design is a focus-by-wire AF implementation. FTM Full Time Manual focusing is supported if enabled for electronic manual focusing lens is selected in the camera's menu - the default, the focusing ring does not turn during AF. The lens' switch must be in the "MF" position - and the camera meter must be on/awake - for manual focusing. If the meter is inactive, MF does not function. The focusing ring size, like that of the rest of the lens, is tiny. However, being positioned at the outer-most position on the lens barrel, the MF ring is still quite usable. It easy to rotate and reasonably smooth. Expect some modest subject size change in the frame when pulling focus on this lens. The front filter threads do not rotate with focusing, though the lens' inner barrel extends modestly at minimum focus distance. There are no focus distance or DOF markings provided. There is no room for a window for such, and since the focusing ring is not directly connected to the focusing gears same as with USM AF implementations, printed markings are not available. Most AF lenses produced today have no significant DOF markings. I doubt that anyone using this lens will care about these missing features. The Canon EF 40mm f/ STM Lens was introduced with the Canon EOS Rebel T4i / 650D DSLR. The T4i press release revealed that "When used with Canon’s new EF and EF-S STM lenses, the camera can provide smooth and quiet continuous AF while recording video." I don't doubt the "smooth" portion of that claim, but I'm more skeptical of the claim that the Rebel T4i will not capture focus motor sounds during video recording. My T4i Kit did not ship as of review time, but I can tell you that the 40 STM is not a silent focusing lens. While not as noisy as the Canon EF 50mm f/ II Lens for example, the 40 STM emits a buzz when focusing. The noise is not bad, but I do expect some buzzing motor noise to be picked up by an in-camera microphone even on the Rebel T4i/650D - unless a sound cancellation or other technology is employed. Update Confirmed. The 40 STM's AF sound is easily audible in Rebel T4i video when using the built-in stereo mic. In AI Servo mode, the 40 STM performs quite well. Honestly, I thought it would fall apart when given a reasonably challenging target. Of course, finding challengingly fast moving subjects that fill a 40mm frame and do not impose a safety hazard to the photographer is a bit of a challenge. The DOF at 40mm and f/ is rather deep at the distances most often used for this purpose. My hit rate on the cantering/jumping horse shown above was quite high. I much prefer the 40 STM's focusing system to the systems found in the Canon EF 35mm f/ Lens and Canon EF 50mm f/ II Lens. The 40 STM's 300mm MFD Minimum Focus Distance will deliver a MM Maximum Magnification. This is a relatively low value, but a typical value for a prime lens.

The Canon EF 12mm Extension Tube II takes the MM value and the Canon EF 25mm Extension Tube II takes the MM value This lens is not compatible with Canon's extenders. If you look at the comparison photo at the top of this page, you will see that it appears like the extender would protrude half way through the 40 STM. This is a bare bones lens - but it feels well made. The body is constructed of engineering plastic with a standard metal mount. The other external components include a single switch, an extending inner lens barrel and a tiny MF ring. The MF ring has very little play/wobble in its design.

You will not have to worry about this pocket lens blocking your DSLR's built-in flash. Some of Canon's tiniest lenses are shown below. Positioned above from left to right are the following lenses Canon EF 40mm f/ STM Lens Canon EF 50mm f/ II Lens Canon EF 28mm f/ Lens Canon EF 35mm f/ Lens Canon EF 50mm f/ USM Lens Unfortunately and as with most of Canon's non-L lenses, the Canon EF 40mm f/ STM Lens does not ship with a lens hood included. I typically recommend using a lens hood most of the time, but not in this case. I fail to understand the purpose of the thread-on Canon ES-52 lens hood shown above. It is far too shallow to block any appreciable amounts of light - even from a far wider angle lens. And it is far too shallow to provide any appreciable protection from physical incidents. Perhaps I just need someone to set me straight on the purpose of the ES-52, but I think it is a complete waste of money and couldn't even bring myself to buy it for the product pictures. I'm not sure that this inexpensive lens justifies a protection filter, but the small 52mm filter size keeps the price low. Circular polarizer and ND/graduated ND filters are of course vey worthwhile to have - and again, 52mm filter are among the smallest and least expensive available. No case is included in the box, but this baby lens could really use a cute little pink or light blue storage pouch. A LensCoat would also be cute. The Canon EF 40mm f/ STM Lens is a member of the "Canon EF" family of lenses. This means that it is compatible with all Canon EOS cameras as of review time. Interesting is that Canon released an EOS 5D Mark III firmware update to improve functionality with the stepping motor in this lens. I'm not sure how this fixed issue relates to all previous EOS DSLRs. Overall, I’m finding very "little" to not like about this tiny, inexpensive lens. It is not hard to justify this purchase. Keep a pancake in your pocket - even for use as a backup lens. Bringing you this site is my full-time job typically 60-80 hours per week.
