Lon, As others have mentioned, there are two A35-70 lens. The constant aperture f4 one is a bigger two touch. The smaller variable aperture is a one touch zoom. I remember barrel distortion on both at the wide end. (not terrible, but you can see it if you have the right subjects) I believe the f4 is a bit better in optical quality, but heavier/bigger.
I think the A35-105/3.5 is a better lens than either 35-70. Optically and mechanically is feels and looks better to me. It's the A zoom I would walk around with. Regards, Bob S.
