 "Awesome" 2009-06-09
By Marcio Jose Bastos Silva (Vermont, USA)
I bought this lens some time ago and have taken several photos with it since then. I can assure you that despite this lens is quite inexpensive and made maily of cheap plastic, it produces wonderful photos! Sharp on all four cornes! Do not buy that Canon 50mm lens if you have a 1.6 crop factor camera such as Canon Xti or Canon 40D because it will become a 80mm! This Canon AF 28mm F/2.8 on a 1.6 crop factor Camera is actually a 44mm and will do the job much better. It is very light and fast. I really enjoy to connect this little lens to my Canon 40D and go around the city capturing all that I find Interesting. The ony thing I would say against this lens is that it is not a USM lens what means that the auto focus is a little slow sometimes however, for the price it is what you get and I really do not not care to wait a few seconds more for the focus mecanism to lock on the subject of my photo. I RECOMMEND THIS LENS! IT IS A JOY IN MY LIFE AND AN EXCELLENT TOOL... FOR PROFESSIONALS AND AMATEURS....

 "Sufficient quality and decently fast, but noisy" 2009-04-03
By Peter Pallock (San Antonio, TX USA)
I have been happy with this lens so far, using it on a Canon 30D body. The glass is decent quality, without any significant vignetting. It's not particularly wide angle, due in part to the 1.3 magnification factor on the 30D, so not great for getting the full room at a party for instance, but works well for landscapes and such.



My only complaint with it is the noise when focusing, which is significant, and can be distracting if you're shooting a wedding or conference where noise is an issue.

 "Great price...almost as good lens." 2007-12-31
By B. Jaber (San Jose, CA United States)
Great price for this 2.8 lens if you do a lot of architectural work. On a crop factor body (I used it on a 30D and 40D), it produces virtually no distortion. Only gripes are that is focuses slow and noisy.

 "So-so. But worth considering." 2007-05-07
By Matt
I bought this lens for a couple of reasons. First of all, I picked it up REALLY cheap used (and you can get it quite cheap even new). Secondly, I really wanted a standard-view lens for my Rebel XT. But honestly, I can't say that I am extremely impressed with it. Simply put, the sharpness is just not there like it is with, say, the 20mm f/2.8, 35mm f/2, or 50mm f/1.4. In fact, sharpness ranges from equal to worse than the 28-105mm (depending on aperture). There also seems to be somewhat of a decentering effect, where the right side of the picture is ESPECIALLY soft. And chromatic aberrations are on the high side. Honestly, I don't now how Canon went wrong with this lens, as the 35mm f/2 is a VERY similar design and actually a GREAT lens. Oh, and like the 35mm f/2, build quality leaves something to be desired.



On the other hand, it IS better than the kit zoom. And even though it really can't beat the 28-105mm in terms of sharpness, it DOES beat that lens in terms of contrast and color saturation. Oh, and it is cheap. So it may at least be worth considering. But overall, I would pass on this lens in favor of the MUCH better 35mm f/2. Of course, the 35mm f/2 is somewhat pricier than this lens (but well worth it).

 "A good all-around "normal" lens" 2006-11-02
By L. Da Vinci (New York, NY)
If you could only carry one lens for your Canon digital SLR, or you wanted to keep your gear to a minimum, this would be the only lens to carry. Of course, you would be limited in your range of photography, i.e. no large groups of people in small spaces; no sports photos.

Otherwise, this is a very good lens for all-around photography.

With the large maximum aperture, excellent background blur is possible even with a fast shutter speed. The aspherical lens element makes the lens compact and corrects spherical aberrations. The image is sharp even at the edges. Lead-free glass is used.

 "Very good lens" 2009-12-08
By Scapesdog (Atlanta, GA)
Very good lens. Not the best one Canon offers but does exactly what I needed.

I considered buying Canons 24mm 1.4 L for about a year but could not justify the price. I could buy three of these for the price of the 24mm.

All i wanted was a good low light, fast, lens to take candid shots with out the crappy flash on the camera.

The images are great. Actually converts to about a 44mm film lens on my DSLR.

No regrets.

 "Compact, solid build, fast/quiet focus, but sensitive to shake, expensive" 2009-11-14
By Omar Siddique (Ellicott City, MD USA)
Solid and compact, this lens focuses fast, taking crisp photos, but is a bit expensive, sensitive to camera shake, and has an odd effective-focal-length.



The USM AF is quiet and fast, having no trouble finding focus even in very low-light, attached to my Canon EOS Rebel T1i 15.1 MP CMOS Digital SLR Camera with 3-Inch LCD and EF-S 18-55mm f/3.5-5.6 IS Lens.



However, in the same low-light (nightlife) situations, shooting at Av f/1.8 - f/2.5 (ISO1600), I experienced notable blur. The lens seems more sensitive to shake than I expected; that might just be me, but I think it would benefit from IS. Images seem a little soft at f/1.8, sharpening up by f/2.8, but are usable all throughout the range.



Important to note: on cropped-sensor cameras like the Canon Rebels and 40/50D (check Wikipedia for "APS-C" and for "Crop Factor" for details), the 1.6x crop-factor means this lens is effectively a 45mm. That's kind of an odd focal length. I have to back up several feet behind where I'd be with my miniature-looking point&shoot to get the typical "small group of people" shot, but a close-up or typical face+shoulders portrait requires cropping.



This seems like the right focal-length for focused outdoor shots (where you're shooting one subject with some of the surroundings), kids+pets, and general walk-around purposes. The short length and broad aperture also makes this a good walk-around lens, although the limited wide-angle was sometimes frustrating.



The lens is solid and heavy, feels very well-constructed, with "big" glass.



I found the colors slightly cooler and images slightly softer than the Canon EF 50mm f/1.8 II Camera Lens. Compared to that much cheaper lens, the EF28mm feels much better made, is much quieter, slightly faster focusing, and has a more usable focal length on APS-C cameras.



I found the quality and colors nearly identical to the Canon EF 35mm f/2 Wide Angle Lens for Canon SLR Cameras. Compared to that cheaper lens, the EF28 feels better made, is much quieter, much faster focusing (especially in low-light), and is slightly more useful than the EF 35mm's effective APS-C length of 56mm.



Recommended for multi-purpose use, but outdoor-only photographers may do better with the cheaper Canon EF 35mm f/2 Wide Angle Lens for Canon SLR Cameras which is much noisier and focus-hunts horribly in low-light, but takes comparable photos for being notably cheaper/smaller.

 "Okay lens, but could be much better for the price..." 2009-11-06
By E. Burd
I rented this lens for a week to see how it would perform. I tried various shots indoors and outdoors in a variety of settings.



I was looking at a wide angle lens for my XSi, which is a crop factor, so this would end up around 45mm on a full frame.



Good:

1) Very fast focus

2) Able to perform a manual focus override

3) Lightweight and small

4) Good bokeh



Bad:

1) You need to stop down to f/4 in order to get anything resembling a sharp image. The center was generally fine, but the corners were terrible, even on a crop camera. This was an huge disappointment, as the 50mm f/1.4 was razor sharp at f/2.

2) I noticed a lot of CA until you stop down to about f/2.8, when it became reasonable.

3) Price - it's a little high (~$500) considering you can buy the 17-40 f/4L for about $200 more, and you get more focal range to boot.



Overall, I was very disappointed with the results, especially when this was after using the 50mm f/1.4, which was simply incredible. You would be better off in the long run by purchasing the 17-40 f4/L, which is what I'll be purchasing next.

This is a great lens I was able to use right away for a conference. I was able to get multiple shots without the use of a flash.

 "Not worth the money" 2009-10-20
By P. Verlee (Bangor, ME United States)
Good looking quiet lens, but my version is very soft, not even close to a 17-55 f 2.8 EFS zoom. This puzzles me, since the zoom is not for a full frame and is a zoom. But after testing the 28 f/1.8, it doesn't start to sharpen up till 2.8 or above. which means the 1.8 stop is useless. it's not much sharper at 2.0 or 2.2. It also has flare, lots of CA and doesn't always focus correctly. By comparison, my 17-55 F/2.8 is razor sharp even at 2.8, focuses perfectly every time, and has image stabilization. Big disappointment from Canon. I wonder why they don't introduce primes for EF-S. I have an XSi, 10-22, 17-55 f/2.8 and the 70-200 f/2.8 IS L (a razor sharp lens!) so I guess I don't need any primes. Save your money and spend it on the camera (7D), not this prime lens.
