You guys also need to consider ergonomics and build quality. I loved the size of my Canon 35, but it broke during a trip to Spain. The aperture blades fell out of place, never to return, and they were loose in the lens. No one could repair it.
I am quite sure this lens was produced for a long time (into the 1970's?), but it may be of lower build-quality than the VC, which would be brand-new.
