I have been a stalker on this site for a few months and have been impressed with the knowledge and expertise of the members. This proves it. Thank you for the fast responses.

I am a hobbyist with a Canon Rebel T2i and am looking to upgrade to a full frame camera, probably the 6D if I stay with Canon. My lenses were purchased for use on my last film camera, the Rebel 2000. I recently resurrected my darkroom so I would like to stay with Canon if possible and continue to shoot some film.
Canon's 6D marketing materials cover a feature that might allow me to use some of my older EF lenses and get better results than on my T2i. This is the Peripheral illumination, chromatic aberration, and distortion corrections that are available and programmable through a menu of different available EF lenses. Will this work with my 24-85 f3.5-4.5 and produce images worthy of the 6D? Or should I plan on buying the 24-105 L lens? BTW, this lens will be my snapshot lens. I plan to add the 17-40 and 100-400 lenses for my version of artistic photos. I checked the User manual, the only manual that is downloadable for the 6D, but I need to look at the software for the lenses that are covered.

Thanks,
Leland
