i used both before, and i personally would recommend the Canon. its cheaper, lighter and has good enough image quality.
Not to say the sigma is a bad lens, but the design is kinda dated and it is a lot bigger/ heaver with slightly faster aperture only. also being older sigmas, there are chances that you will be fighting with back/front focusing and it is super frustrating.
Oh gosh, yes I heard about the AF issues. It's always a hit and miss. ART version Improved this I hear. But that'll blow my budget.
I used the canon 1.8 ii before, and build quality wise, not so nice. At least it focusing speed is real fine.
How about the canon 50mm 1.4?
many says it's old, and really bad build and one fragile piece of
glass.
Or do you have any lens to recommend?
