Hi Don, it's 3 in the morning and I just finished packing my backpack for christmas (I am leaving the city for a while <g>), so just quickly before I go to sleep... I have had a Sigma from what I believe is similar period - 75-200 2.8-3.5 (manual focus). It wasn't a bad lens, but: 1) flare - in my experience the fast Sigmas from that period (also the 28-70 2.8 first type before the EX types) exhibit lot of flare, both reflections and veiling glare. So look out for that. 2) build quality - my wasn't exactly good :-( The zoom was quite loose, the whole lens wouldn't stay at IMO, Sigmas from that period aren't so good. They are sharp but their other characteristics I didn't like OTOH, the 3.8 might be different in both regards. I never tried that one. If you can live with manual focus, I can well recommend the Tamron SP 70-210 3.5 I had it before getting an 2.8 zoom and it was quite good, both mechanically and optically. Actually, the build of that lens was amazing <g>. Sorry for not providing a good answer :-( Good light! fra
