Peripheral Illumination Correction

[rpcrowe]

I have noticed some rather heavy vignetting when I use 100-400mm f/4.5-5.6L IS Mark-II lens on my Canon 5D Mark-II camera; especially at longer focal lengths and wide open. No problem, of course, when I use my &D Mark-2 crop format camera...

I can update the in-camera peripheral illumination correction on my 5D2 to include the 100-400mm Mark-II lens but, I can also correct the vignetting in Adobe Camera RAW as I did with this image which I shot at 340mm @ f/5.6...



Since, I always shoot RAW, this is really no big problem.

I wonder which gives better results: in-camera or ACR correction? I am sort of leaning towards in-camera correction, since there may be sometime that I want or need to shoot JPEG rather than RAW with this camera/lens combination...

Is the in-camera vignette remove available for raw or is it restricted to jpegs only?

I personally prefer doing it in PP because I have more control. I find that the default settings are fairly conservative and I sometimes have to go in and tweak them manually because the vignetting is not removed 100%. Sometimes I want this and at other times I don't, depending on the image content.

Thanks, Manfred, that is just the kind of information that I was wanting.... I don't shoot with a combination of my 100-400 Mk=2 lens and 5D2 very often. Most often, I use that lens on my 7D2 crop format camera...

I will, sometimes use a combination of 70-200mm f/4L IS lens on the 5D2 and the 100-400 Mk-2 on the 7D2 camera.

I plan to use that combination for the Red Bull Air Races over San Diego Bay, next month...

I don't think the in-camera settings affect raw files.

Depends on the camera and to a degree the lens. All of my Fuji raw files taken with a Fuji lens are automatically corrected upon import without any user input. I wondered about this when I first got it as I tried to apply correction as I would have with my Nikon and Pentax files but couldn't find a way of doing so, turns out it there is a dialogue box showing it was already done:
