I was considering the Zeiss 50mm 1.4 (canon of course), but then it's more expensive than the canon 1.2L 50mm. But I read that the Zeiss suffers from the same problem as the canon (50 1.2L) with the whole focus shift thing. Then I also read in one of the comments and reviews that it can be "easily" fixed by pressing the DOF button on the camera everytime you take a photo. That, to me, is a bit finicky. Can I just say that I find it a bit weird that a company/store (e.g. B&H) sells the canon 1.4 cheaper than the sigma 1.4. Yet here where I live (at least one store) is selling the sigma 1.4 cheaper than the canon 1.4. What's up with that? I am tempted to get the sigma in that regard and other factors that I've read from reviews than sigma 50mm 1.4 is better than canon 50mm 1.4.
As I've said I'm leaning towards the 50mm 1.4 (price is a big factor) but I don't understand how the filter would attach to the lens as the front bit extends about 1cm? Wouldn't the front part of the lens extending prevent the filter from being attached??
on the canon 50 the filter threads are on the part that extends, I got one of the cheap ebay hoods for it for about 3 bucks or something and a little neoprene bag to keep it in the lens just fits in the bag then i put the hood over the bag and it is barely bigger than the lens alone but very well protected
