This is a good point. At 24 I do get a lot of vignetting on my 5D. It's easy enough to fix in LightRoom but it is that extra 30 seconds or whatever of work per image that adds up after a while. I still won't give up my 24-105 of my 5D, but this is a good point.
Filter by camera and focal length, make a vignette adjustment to all the images at once. Total time required: 45 seconds max.
Or even better, leave the vignette in. If there's no vignette I often add it anyway.
EF 24-105mm F/4 L IS USM
Get a 70-200mm on this camera - simply amazing.
