Everything on imaging in very good, but the only one disadvantage is its weight

The weight was both impressive and at the same time, a little annoying - but there's a lot of glass in this lens, and for a 50mm, it's HUGE.

Better lens overall than pricier CZ.CONS:1) Weight and size.

My only complaint about this lens is the weight.

If weight is a concern, just buy the Canon 50mm f/1.4.Compared with the Canon f/1.2, the Sigma is sharper, no doubt

it was really really sharp as I

(I also think it's way better than Sigma's non-ART 50, which I found worse than Nikon's 1.4G in terms of its low light autofocus ability as well)

I later tried the Nikon 50mm 1.4G and I was not happy with its performance, I then owned the Nikon 1.8G and although better than the 1.4, I never really fell in love with that one

Still works great with PDAF 79 AF points, so I don’t really miss H-AF much at all on this lens.
