Vignetting on 24-70 F/2.8L II USM
« on: December 13, 2012, 07:53:54 AM »
I picked up a new 24-70 F/2.8L II USM this week and from initial shots, it appears to have very bad vignetting.  I'm not sure wether I'm expecting too much, or whether I have a duff copy?  Due to work stuff I haven't really been able to test it properly, but so far, I'm not very impressed.
I'll upload some test shots this evening when I've got a bit more time free to play about with various focal lengths and f numbers.

Wide open, you should be seeing nearly 2 stops at the wide end, and about 1.3 stops at the long end.

If you have same amount of vignetting at 4 corners @ 24mm to 30ish, then yes...it's normal for the new 24-70 f2.8 II. I tried 2 copies and both have similar vignetting at that range. You should be able to fix that vig. in LR with just 1 click

What about sharpness?

Wide open, f/2.8 at 24mm I expect a lens this expensive to have abolutly no vignetting.

But then after a bit I get over it. Dylan777 is correct it does have vignetting. As he said as long as it is equal you should be ok.

I have one..it vignettes pretty severely at the wide end...at first I thought it was the normal-depth B&W filter that I put on the lens..as it was just at the very edges...have been meaning to find a white wall to test it, with and without the filter @ 24mm.
My copy seems very sharp...I did test that against my Sigma 50mm @ 2.8 & 8.0 and I would say that the two lenses are equal in sharpness. amazing for a zoom...so I am not throwing it out ( although the price tag still hurts).
I will try to test it out at the wide end with and with out the filter and get back to you here.  I am curious, too!

The 600mm f/4L IS II costs $13,000 and has about 1.5 stops of vignetting wide open.   ::)

Have you considered sending it back   :)

I don't know if you get over it...but you learn to live with it BECAUSE the lens is SO sharp and REALLY has great fit & finish. Feels incredible in the hands, (and I cannot believe that I am saying that about a zoom). I never felt that way about my 24-105.

@ infared - It sounds like you have a good copy. Any AFMA on your lens? I did, but I do not see the differences in real life shooting. I might need new glasses here....

I'm using B&W Clear filter. I tested with & w/o filter and the results are same. Stucco wall was my target.

The vignetting and a few other reasons help answer the question, can I replace my 24mm or 35mm L's with this lens.

Put my head down and look at ground....LOL...I have not gotten out the tripod and done that...although when I compared it to the Sigma I was looking for AF accuracy in-passing on the sidelines and my 24-70 seemed to be spot-on.  I compared the lens on a close up shot that had great detail. (an OMD camera body.)...
I gotta go to work!
I will check in later

Is you need super-low DOF in your wides, no.
I was torn...but ended up going for the versatile zoom instead of buying the Sigma 35mm and the Canon 24mm L, (same money being spent).  Definitely a TOUGH choice.

Well yes my need may be a super-low DOF in my wides. Not what I was referring to though.
But, there are other things to. Such as distortion.

I didn't see the differences with or w/o filter. Vignetting still appear at 4 corners evenly at f2.8.
