I missed the first part of this discussion. I have a couple of Sigma's- the EX 50mm f2.8 macro and 14mm f3.5 - and they work fine. No compatibility problems at all. I finally broke down and ordered the Sigma 70 - 200 f.28 as well, but have not recieved it yet.
If anything, I've had more compatibility problems with my Tokinas - the ATX 100-300 f4 zoom is inconsistent on the "A" setting - sometimes loosing the connection at defaulting to fully stopped down. It always failed to connect with my old Pz-70. The aperture display disappears and is replaced by the two dashes "- -" when this happens. And my ATX 400 f5.6 is very finicky with the Mz-S. Sometimes the finder reports really odd f stops (like f99) and sometimes the AF cam doesn't engage. Remounting the lens solves both problems, which are fairly uncommon. I think sometimes it's just the individual lens itself. - MCC At 11:15 PM 11/6/01 -0500, you wrote: >After nearly 10 years of using Sigma lenses I'm actually becoming >disillusioned.
