My mistake. I didn't realize Sigma had two 'Digital' lens lines.
Although I have to wonder what 'Designed to suite the special
characteristics of digital cameras.' means on a full frame lens.
Marketing hype over the use of the magic word 'DIGITAL'? How is
it different from their other FF lenses?
Why would you want to use a vignette producing lens? I would think
a DC or EFS lens would be useless on a 5D.
( yes it would produce an image )
Or are you using them to produce panos where you just set the crop
circle?
