let's say I'm in awe with the

Leica Summilux-M 21mm f/1.4 ASPH, man that is one beautiful lens, I wonder if the nikon's 24mm f1.4 have that kind of rendering.

As I'm thinking of moving up to A7 I'm planning some cheap voitlander glass to go along with Sony.

 

So here are my 2 choices 15mm f4.5 and the other one 40mmf1.4, anyone has any experience with these lenses?
