50mm 1.8 ef ii:
Pros:
Autofocus(seems to be pretty fast, can somebody shed some light on whether it's faster than a tamron 17-50(and by how much)
light as hell
New(not really too bothered by this though but at least I'll know for sure the condition is good)
Cons:
weak build quality apparently(although that won't be much of a problem for me)
More expensive than the vintage lenses
50mm 1.4 vintage:
Pros:
f/1.4
solid metal build
cheaper
cons:
no AF
heavy
Also people rave about how sharp the super takumar 50mm 1.4 is even at 1.4, but so does everyone about the 50mm 1.8 ef ii so I was wondering if anyone knew which was better in that respect.
