Summary: Canon EF 20-35mm f/3.5 - 4.5 USM Wide Angle Zoom Lens for Canon SLR Cameras. Easy to use,very sharp pictures, it is a strong lens, good autofocus system, the luminosity is really good. It's a light weight lens, not heavy.
Conclusion: I bought this lens second-hand off craigslist. It came with a it's dedicated Canon lens hood, a Canon EOS Rebel G 35mm body, 500 sheets of 4x6 photo paper, 400 sheets of 5x7 paper, and probably 50 rolls of various types of film. The entire bundle was $230, which I think is quite a deal.
Pros: VERY lightweight, USM, 20-35mm, quite sharp
Cons: Bit limiting on a 1.6 crop body- but once you learn how to combine them, not a problem.
Summary: This lens is good for those who are looking to get decent wide angle but don't have the budget for the EF 17-40 f/4L. In order to beat the quality of this lens you need to spend almost double. I used the 20-35 on my Rebel XT which makes it equivalent to 32 to 56mm.
Conclusion: Ok so I was searching for a wide angle lens to compliment my 35L. I first purchased the 17-40 but wierd distortion showed up on both copies. Then I tried the 16-35 and I was very pleased with it colors and contast and center sharpness. All in all a good lens.
Conclusion: I usually leave my 24-70 f2.8 lens on my camera. But when I want just a light "snapshot" lens, I will throw on this 20-35. It allows me to use the built in flash of my 20D and covers a nice range. For instance taking a group shot at a dinner party is possible at the table using 20mm.
Pros: light weight. No vignetting of built in flash, good range on crop cameras & quiet focusing. Excellent price.
Cons: Not as sharp as I like. Dull corners at 20mm. Colors seem a bit dull.
Conclusion: I bought this lens second hand for AUS$400 about a year ago, and have been very happy with it for the price. I use it with film, and the wide angle range is great for landscapes and creative close-ups.
Pros: Cheap, light, reasonably sharp. Close enough to 'L' for me.
Conclusion: I bought this used from Park Cameras, UK. It was supposed to be in 'nice condition' but is anything but. It is very marked all over, the hood has a split in it and it stops a little short of 35mm at 33mm. Do they bother to check these lenses before selling them? However, I like it.
Pros: Good optically, nice contrast and colour, ring USM with FTM. It is small on contrast to my other lenses and so will travel easily.
Conclusion: I recently did some tests with 1:1 enlargements and found out that there is indeed a large difference in sharpness between wide-open and say, f/8. Not that it's bad. Not at all! A fine lens which is really versatile and very suitable for landscape.
Pros: nice wide-angle range, sharp, good build quality
Cons: not as sharp as I expected it to be at wide open.
