Michael: Caution, there are many negative posts on the sigma having compatability issues wht the Mark II lens interface. Looks like SIgma may have some homework to do.
Hello Ben. Very impressive wide angle, slow shutter shotl with your 5D. I am curious to know if this Sigma 12-24 lens will be just as proficient with my 5D Mark II. I can not seem to find any meaningful samples with that combination. One might think that the lens should work the same on the 5D mark II as the 5D .... but with Canon, you never know. Michael.
