Why do you think, did Sigma for only for a f/1.4 rather than down to the f/1.2 of the Canon L 50mm ?
Because it's going to be 815g with f/1.4
The extra glass for top performance at f/1.2 would have been an overkill. I'm more surprised that Zeiss didn't go for f/1.2 considering they definitely had the budget.
I am hoping that this lens is going to be pretty sweet at f/1.4...and focus fast. I think that the size and the ensuing focusing issues, oh..and cost of an f/1.2 lens...would be offsetting. I don't think f/1.2 is necessary if this lens is what we are hoping that it is. I am just excited that they are making this lens..REALLY excited!!!!! The lens makers have been asleep for decades regarding this FF normal lens situation.
