If you want the absolute best image quality the Zeiss Otus, if you want the fastest the Canin 50mm f/1.0 and the Sigma 50mm f/1.4 ART if you want the best autofocus 50mm.
I saw some pictures of that Canon f/1.0 recently. I had never heard of it till then. Wasn't that impressed but couldn't tell if it was the lens or user error.
I want to know what is the best 50mm lens for a Canon full frame. Price is not relevant. Thanks.

Have you not already got the 50mm F1.2 L ? This is a stonger of a lens is it not ?

No I do not have that lens yet. I see a lot of people suggesting the sigma but from what I read it is not even close to as good as the 1.2 Canon. I posted this because I was thinking hard on buying the 1.2 but want to make sure I am not over looking anything else.
I can only assume this is the case. Although you never know what ol ken Rockwell has been saying. I think he was the only person to slate the 35.The new Sigma 50mm f/1.4 ART is better, are you sure you're not looking at the older Sigma 50mm f/1.4 vs the Canon?

No idea what you are reading, but I haven't yet seen a bad report of the new sigma, or many of the old for that matter.
The new sigma is as good, if not better than any 50mm available except for perhaps the very expensive Zeiss one.
It seems you are set on the canon regardless, so you may as well just buy that.

You asked "what is the best 50mm lens for a Canon full frame. Price is not relevant."
but then said
"I have the opportunity to buy the Canon 1.2 for the same price as the Sigma and I can't afford or want a manual focus Zeiss lens"
So perhaps you'd like to be a bit more specific about budget, purpose etc?
sigma art lenses are really good value for money and I think are soon going to be the preferred lens over zeiss

Sigma 1.4A

Looks more like an elastic band.

Even if the Sigma is better - some people will crave the L Canon to the point that they will even buy it knowing it's inferior.
Good to see Sigma giving people a red ring to make them feel better about themselves lol
I don't crave the red ring, I care more about the final results so just get whatever is best bang for buck really, besides, I have enough red rings![]()

Back to the original OP, I had no budget too, well except the Zeiss, I ruled that out because manual focus on this kind of lens is stuck in the 50's, on a wide angle for landscape I understand, for a 50mm and more importantly for what I need it for, AF is critical.
So I ended up with the Sigma and have absolutely no regret, it is built nicer than some of the Canon Ls too.
Which Canon L is it built nicer than?
