Rich, I have the 28, 35, 45 and 90. Got the 35 much later since 45 was often too narrow and 28 too wide for me. So I changed lenses a lot and bought a second body to avoid frequent lens changing. Which had the negative effect that now I usualy had different films in them 🙂
When a 35 turned up for a sensible price I got it and I have to say that it's my most used lens now. One reason is the perfect, for me that is, compromise between wide and normal and it is a good performer, much better than what the labs make from my negs and what I can get from my scanner.
It may not be stellar, but it outperforms everything else I have in this field of view, may be with the excpetion of the SLR Distagon 35/2.8.
