Reviews and Problems with Canon EF 24-70mm f/2.8L USM
Showing 1-10 of 21

Conclusion: Not as good as a good 24-85mm f3.5-4.5 .
Pros: Though heavy on a 1Ds it handles well and the hood protects against rain as well as against flare. autofocus is good and it balances well with my body
Cons: But, and it is a big but, I have so far had the use of four new ones, none of which is anywhere near as good as my 24-85mm f3.5-4.5mm. Curvature of field is so bad that it is like a magic lens. You can focus across a wide street at buildings on the other side, shooting down the street, and getting focus confirmation on the central AF point as usual, and where the point is focussed it will be sharp, but whereas my 24-85mm at 24mm will render everything in focus even at...
Conclusion: I rented one of these from a vey reputable shop after my 28-70L was stolen. Now, especially after reading some of the comments here, I can't decide if I really want to buy one or look for a good used 28-70L. First of all, when I cranked the lens all the way open to 24mm, it "locked up" there. Like there's a light notch in the barrel that intentionally holds it at 24mm.
Pros: Wider aperature than the 28-70L
Cons: Weight, "Bad Copy-itis," lock-down at 24mm, doesn't register images with 580 EX
Conclusion: I have too many ruined shots to recommend this lens. Typical Canon mediocre quality of their wide angle lenses. I only shoot full frame 5D and 1Ds Mk3, so for APS sized users it may be a better performer.
Pros: Great focal length range.
Cons: Poor performance. To soft on edges compared with prime lenses to be useful for landscape work.
Conclusion: I recently bought a Canon EF 24-70mm f/2.8L USM lens for my Canon 40 D and found that in bright sun light IQ was fantastic. Build quality was excellent, presence of the lens is unrivalled, you could walk in to a room full of photographers and get attention immediately. Pin point sharp pictures that could be blown uo to any size without loosing sharpness.

Cons: But in low light and in Flash light photography the Canon EF 24-70mm f/2.8L USM used in conjunction with either 40 D or 400 D gave images that were soft. Very disappointing and painfull after reading some rave reviews. I sold the lens at a loss to someone who did most of his photography outdoors.
Conclusion: A dissapointment. My Sigma 15-30 performs way better than this lens. Okay, I might have gotten a bad copy, but at this price point, one would think you should'nt have to worry about such things. Thumbs down for Canon.
Pros: Stopped down to f/4 and smaller, it can produce some nice shots. Built like a tank and very fast AF.
Cons: A huge amount of money to spend on a huge, heavy piece of glass, which is, at best, only mediocre.
Conclusion: My use of the 35mm format revolves completely around this type of lens. After buying four copies of Canon's 24-70 lens, I gave up on it. First, like the other reviewers, I couldn't find a copy that was sharp at f/2.8, which is unforgiveable. Second, the close focusing, while never the strong point of such a lens, was just abominable. After trying Nikon's 28-70 f/2.8, I dumped Canon and switched over to Nikon.
Conclusion: Well, much cheaper and smaller lenses have similar or better image quality at f8 or f5.6. At f2.8 this lens is a looser. Wide side is so soft, simply not usable. Not a practical zoom range IMO considering the alternatives. "Big and heavy" is never a problem for me as long as a lens does its job. (I use 70-200IS+1.4Ext+1DM2 and never complain, for example!) But this lens is so limited and its hugeness and weight start bothering me. So why?
Pros: Good Quality Closed down.
Cons: Wide side is soft, at f2.8 not usable. It has a problem with color rendering.
Conclusion: Allow me to be the only person on this site that gives this lens a bad review. I read almost everything that you guys have said about this lens and I after thinking about it forever, I bought it. For those who love this lens, I have to say great. But those guys who are thinking about this lens, make sure you go to a store and see it and hold it in your hand and on your camera. It is a heavy brick ( 2lbs) and huge in size.
Summary: Having read so much about this lens and the great quality imagery that it is capable of producing, I have been nothing but dissapointed by the results. I primarily take photographs at night (light painting) and thought that this lens would be perfect with its 2.8 aperture, but I have struggled to get pin sharp images. I recently watched a YouTube review for this Lens and I have learned that you are lucky if you get a good version of it.
