<div>You're 1/3 of the way there already - newer bodies offer Peripheral Illumination Correction, which corrects the vignetting (light fall-off) of lenses in-camera for JPGs. Of course, if you shoot RAW, all of those corrections can be applied with lens-specific presets in DPP. Frankly, I would not want any of them applied in-camera to RAW images - I've found that DxO corrects them better than DPP, actually.</div>

Agreed! A 500mm f/5.6L IS would be great.
