I've got a PZ-10 that I've had from new. Needs a battery, but that's it. I know I can use my old screwmounts on it with my adapter, but anyone ever use a Tamron 17-50 on a film camera? Also wonder about my Sigma 105 macro. I don't expect my 70mm ltd will work without the lens interfering with the 35mm format. What are your thoughts on these newer lenses on an older film camera?

The Tamron 17-50 is not a full-frame lens, so you'll see severe vignetting/dark corners up until you're close to 50mm. You'll also see dark corners with the DA 70.

The sigma 105mm, is a full-frame lens, however, so you'll be able to use it without any problems. All DG lenses should behave the same way.

Thanks for the info Adam. I suspected the DA70 would give me trouble, but I actually thought that the Tamron may have been OK, just because of the size of it. I guess in this case, size doesn't matter.
