Originally posted by NaClH2O it's sharp corner to corner and it renders reds better than any other lens I own. It's main disadvantages are: a) it's a brick of a lens weighing in at 615 g; and b) the macro mode is weird, it works best if you fine focus with the zoom ring. But a) all zooms of that era were heavy and b) it's weird but it works.
I agree with that assessment. I love my 35-105, especially for portraits. It's very very very sharp, and I like the bokeh. "Stack of primes" is not much of an exaggeration, IMO.
Not crazy about the macro mode on the 35-105 because sometimes the subject I shoot is exactly at the engage/disengage point of the ring. On these occasions I just get a little closer or back up. Still, a bit of a nuisance. I really don't mind the weight much, though.
There is actually one zoom I own with a real macro mode. The Tamron SP 23A 60-300 gets you 1:1.55x magnification. Pretty darn close. It's quite an excellent lens.
