I've been enjoying my 35 pre-ASPH Summilux quite a bit. I like the cine look that my copy has been yielding, and I'm getting a handle on what it does in various conditions.
This said, I've always enjoyed working with the 28mm prospective. I've got a "whole grip of 28s" (2-crons, an elmarit, and a new version summaron). All lovely lenses and each fills a niche in my work. But none render anything like the 35 P-A!
Is there a 28 that yields that glow? I'm not a snob, so I'd buy any lens that draws in a similar way.
