Vignetting On Canon 5D - A Small Test

Wed Jul 12, 2006 8:02 am

Hi all,

I want to show some pics to demonstrate the vignetting on a Canon EOS 5D. I'm interested in your opinions and experiences to avoid those effects especially on a 5D (as it is not such an issue on APS/C sensor cameras I think). I think it's also helpful for those who plan to purchase one of the tested lenses to use on a 5D or another camera with a full format sensor. I do not want to demonstrate sharpness or any other characteristics of these lenses. Thats why all pics are downsized to 800x533 because the vignetting is easier to see on such a small size. Most of the pics are shot with a Sigma EX 80-400 4.5-5.6 OS DG and some with a Canon 70-200 2.8 L USM. All shots taken with ISO100. I have only chosen pics where the aircraft doesn't cover the whole picture because vignetting is much better visible in the sky areas.

wow. I would return it. I know two people that own 5ds, I asked them if they experience that as bad as this and they don't. Could be they are lucky, but the images they showed me show little if any signs of it.

Honestly, that is not very appealing.

Do you mean the camera or the lenses? Do the people you have asked use the same lenses on this cam? Perhaps I had to explain that I also have lots of pictures with only a little of this effect. Here I wanted to show some extremes.

I thought vignetting was strictly a lense problem?

I had the same problem with my 70-200/2.8 on the 5D. Pictures are okay with f8. I also tried the 20mm/2.8 with f8. Not really good. After all, I sold my camera immediately and changed to Nikon with 1.5 crop. Now I am happy with 12 mio. pixel.

Bjoern now I have a look at it I think that my concern was justified.
It seems you have a serious problem.
Photo 1 and 3 show almost no difference although the aperture changed from F6.3 to F10.
Then again the last Sigma image does not show much vignetting at F6.3 so the problem is not consistent, this is however a more or less a result I could have lived with.
Little vignetting and aperture almost wide open on a full size sensor.

Normally I would be suspicious about the lens but since the Canon shows the same problem the problem can only be in the camera.
It seems your 5D has a problem to adjust the aperture properly.
If it was mine I would have taken it back to the shop for a check.

Good luck with it,
Willem

It's just the way it is unfortunately, no camera problem here ... there are numerous discussions on the web concerning 5D and vignetting. It's no different with the 1Ds MkII. Even some very expensive L prime lenses have this problem on the digital full frame sensors.

I agree with Phil int he fact that on a full frame sensor vignetting will always be a problem. And the 5D in particlar has had complaints made that the 24-105 lens vignetts on it at 24mm wide open. However, i have not seen any real problems with people experiancing vignetting at longer focal lengths, especially not any that bad. I would ask for a replacement camera to be honest. There is no way that it should be that bad at 400mm. Especially when the lens is stopped down.

That's why I don't like cameras with full-frame sensors. But vignetting at 400mm? Something is wrong ....

and F10................. is totally unacceptable what ever brand and or type involved.

This camera is flawed.
If it was not we would have seen a consistent vignetting for every aperture at a given focal lenght but this thing is clearly mixed up.

Even in the unlikely case it is not a camera failure I would still bring it back to the shop and ask for a refund as this camera does not do what could be expected from this equipment.
A camera(in the given price segment) that can't be used wider then F10 is useless and I bet anybody will win the argument about the refund.

First thanks for your replies guys so far!

Quoting Aviopic (Reply 5):
Photo 1 and 3 show almost no difference although the aperture changed from F6.3 to F10.
Then again the last Sigma image does not show much vignetting at F6.3 so the problem is not consistent,

But the last picture is taken at 116mm. I think the vignetting problem is getting more worse with higher focal lenght (300mm and more) and I think this is a general problem, not only a problem with my 5D body.

Vignetting on full frame sensors is reality but on the other hand:

I totally agree with these opinions except that I would bet "..anybody will win the argument about the refund".

I will give back my experiences and dissatisfaction as feedback to Canon. I will try to make some test shots with other 5D bodies to compare to my body and see if the problem is a body-specific one or a general 5D problem. If it is body-specific I think it will be no problem to get a refund. If it is not - hm, then I think I have to activate my negotiating skill...  box 

I just wanted to mention that "DXO optics pro" is a very useful program that can outstandingly correct these vignetting and other problems on many digital cameras even on a 5D but not in combination with the Sigma 80-400 - how sad!

Did you guys see that stitched panorama taken with a 5D at 200 mm? (It's 5 MB).

Think he had to correct vignetting?
