Vignetting on 70-200 f2.8 L IS II USM with 5D mark III

Not necessarily

This looks like typical behavior from this lens and not a hood alignment issue. The lens suffers from light fall off in the corners. Everyone should know this by now. Besides, it's not easy to put a hood on incorrectly.

The location of the sun can make one side of the frame of a sky shot lighter than the other. Yes, even with a hood on. The sun is frame left based on the light reflected on the aircraft. Hence, the left side of the frame is lighter in the corners. Basic photography. Only way to get consistent light across the frame would be if the sun was directly behind the camera and not to one side or the other.

I agree, that looks like vignetting caused by a physical obstruction.

late to the party, but I get the same impression, lens hood not seated correctly?

Pieter has now posted that Canon SA have unofficially announced an "update coming this week to solve the vignetting problem". Me, I'm saying nothing more for the moment...

Re: Not necessarily

Your gray wall shot does look fine at 2.8, the air show 7.1 shot looks suspicious. I recommend you find a white wall somewhere and repeat. You can get some 'darkening sky' behavior, but if all your shots are dark on the right at 7.1 you have a mechanical issue.

At f 7.1 Schwany is wrong about falloff.
However the sky is not an even light source and polarized.

Re: Not necessarily

I can see light fall off in the corners in every one of your example shots. Were they supposed to be proof I was wrong. Maybe you need a new monitor or some glasses if you can't see it. In addition, maybe you should take those same shots outdoors pointing the lens and camera up into a clear blue sky. That would illustrate what the OP is describing better than a stucco wall.

There is nothing wrong with the OPs lens. And if I'm wrong, so are 90% of the reviews of this lens. I own it, it vignettes due to falloff. More when wide open, but it doesn't disappear entirely stopped down.

Yes, I saw that.

If Canon is trying to fix it, it seems to imply simply something wrong with the vignetting correction algorithm, that may not work right for the 5D III 70-200 combo. That's why I asked what type of image was posted (i.e.w as a Canon vignetting correction applied or not). If the algorithm was totally off, it might perhaps give this vignetting (no idea, just wild speculation). In any case, it still would not explain the asymmetry, unless it's unevenness in the sky, as suggested. Still, it seems the sky looks rather homogenous throughout,

Just checked with digital color meter. The sky is homogenous blue, and there is definite asymmetry in the vignetting.

Re: Vignetting on 70-200 f2.8 L IS II USM with 5D mark III

Last weekend I did some testiing with my EOS 5DmkIII, the 70-200 2.8L IS mkII and as a bonus with my 70-200 4.0L IS.

Although (as expected) the vignetting at 2.8 is quite strong I can't find any problems. The vigenetting looks the same as the vigenetting as found in the tests on the-digital-picture.

The examples of my tests are found via:

Best regards,

Rob

Hi Pieter, as I have the same problem, you ever received the answer from Canon?
