200f2 - The BEST beauty lens

I do have a 50f1 (and a 50f1,2 and a 50f0.95 for Canon rangefinder cameras). This lens, although super fast, is not very sharp until you hit f2.0-f2.8. The softness is very interesting though as it is super sharp in the center but sharpness falls off as you move off center. Not bad as a portrait lens but way too short in focal length.

I love the 135 soft focus for portraits. It has a ring that allows you to dial in the softness from totally sharp to quite soft in three increments. It produces softness by inducing spherical abberation. The result is a sharp image with a soft image on top of it. It is unique effect most similar to using Zeiss Softar filters. Very different form diffusion filters.
