Look I know it's a big lens for 50mm. But beyond that it has no issues. NONE. it could even be bigger, or more expensive but then it would be manual focus and then the real issue wouldn't be the lens but the fact that the 5D3 has no interchangeable focus screen. THAT is a much bigger problem then this 50mm lens thing everyone is always going off about (it's just such a ho hum focal length)
For goodness sake,

If you are referring to the Sigma Art, it's a terrific tool but it's far from perfect. It has two pronounced drawbacks and one lesser one.
It is simply a huge lens -- it's the same size/weight as a 24-70 f/2.8L II! For a guy like me that brings 1-2 lenses with me in a smaller bag most often, this is the difference between not bringing a second lens along or having to schlep a larger bag. That's a big deal for me but perhaps not for you.
Second, the inexplicably inconsistent AF has been reported by reviewers I trust, TDP, LensTip in particular. It's not a show stopper depending on what you shoot. An occasional whiff with the AF is not a major issue for a studio / portraiture person as they can proof as they work and spot misses as they go and reshoot. But if you are working a wedding reception, capturing a family event, etc. an AF that whiffs could completely miss a moment, miss a memory, etc. That's a huge deal for me. If I have to chimp each time I'm shooting wider than f/2, the lens is not for me.
And finally, I'm not aware that it is formally weather sealed (whatever manufacturers define that as) so much as it's well built and generally resists dust/moisture. That's good enough for me, but if you live in the Pacific Northwest, shoot coastlines, etc. you may be a bit pickier on this front.
That said, optically it's one of the great bang-for-the-buck value propositions out there. This thing punches it weight with anything.
