There indeed are pre-Ka K-mount Adaptall 2 lens mounts. In fact, I would say that they are even more common (and certainly cheaper) than the Ka versions of the Adaptall 2 mounts (at least, judging by that final authority known as "eBay" - <g>). In any event, I've got at least a couple of K (pre-Ka) versions (easily recognizable since they lack any electrical contacts on the mount flange), but only one Ka version (with electrical contacts on the flange). > I have just tried my Adaptall-2 mount (which I BTW bought from a fellow > PDML'er Jim Colwell) on one of my two Tamron lenses with the "AE" marking. > It's the Tamron 3.5/70-150mm, which BTW is a nice portrait lens - and the > *ist D. > It seems that matrix metering is supported - the EXIF says "Pattern". > Also, unlike K-lenses, there's info about the aperture used, but not the > focal length. That's encouraging news, Jens. As I said in my last post, I will have to do some experimenting (if I can ever find my Ka version mount, which seems like it's hiding someplace...). I did take a look at my SD 70-150/2.5 Soft lens, and it does indeed have an AE setting on the aperture ring, but I think that my SD 300/5.6 does not. The 70-150/2.8 also makes a nice portrait lens, and with built-in variable soft focusing (from full sharpness to moderate softness) as a nice bonus. Fred
