I have been borring a friends f1.7 50mm minolta lens for a while but have to give it back so nows the time to get me a good lens

Just wonder what your suggestions might be if 85mm f1.4 better than 50mm?. ive been looking at reviews for the 50mm from sony and 85mm sony CZ T* so far but am still undecided

if someone more knowledgable on lenses can steer me along thatll be cool
