Hello,


I can't decide between the Zeiss Planar T* 1.4/50 and the T* 1.7/50 for my
new Contax Aria.

In Photodo (www.photodo.com/nav/prodindex.html) 50/1.7 (4.6/5) has superior
MTF score than 50/1.4 (4.5/5) but in Photozone (www.photozone.de), 50/1.4 is
better than 50/1.7 (4.44/5 for the 1.4 and 4.04/5 for the 1.7).


The 50/1.7 is cheaper and lighter but which of both has the better optical
performance?


Thanks,

Pierre.
