Has anybody else noticed that there is a lot of Vignetting in lightroom when shooting raw at 2.8?
Well last night I was trying to see if I could come up with a solution to automate the vignetting correction and I noticed that the Lens Correction profile for the 24-70mm is actually set up for a 1.5 crop factor sensor....


Anyway, I've manually edited the profile and changed it to the correct sensor format and it has really helped.

Obviously, this could be totally wrong, the profile has been made by Ricoh and perhaps they have used it on one of the non FF models? But it does seem very odd considering it was made for the K1

This is my first attempt. I'm going to do a bit of research and see if I can compare it to the built in Peripheral Illumination correction.
