So with the switch back to the Canon system I’m torn since I do not own any Sigma Art glass although it’s always been on the wish list, especially with the 85 Art coming out next month. I generally don’t use primes although I own the 50 1.2 and 85 1.8 for Canon (barely used). I wasn’t aware of all the non-sharp, rejected shots from the Sigma lenses and how it affected workflow. I already have my own problems with focus in low light and reject many photos as it is with Canon. What would be the deciding factors in purchasing new lenses to complete “the kit” (not now, not in budget) – pricing, image quality, software/hardware compatibility (i.e. Sigma and 5DM4 or Mac OS Sierra), workflow lengthening? Is there a major difference in number of shots taken with the equivalent prime focal lengths from Canon and Sigma Arts during an average wedding? Thanks for any opinions!
