Despite my earlier dogmatic statement about K and Ka compatibility with the Adaptall 2 mounts, I'm going to have to look at it again. The only Tamron lens I've used with my fairly new DS is the 500/8 SD mirror, and I was using just a K-mount version of the Adaptall 2 mount with it (at f/8, of course). I am going to have to dig out a Ka version Adaptall 2 mount (I've got one sitting around here someplace) and try it with my other Adaptall lenses - an SD 300/5.6 lens and an SD CF 70-150/2.8 Variable Soft lens - both of which are from the pre-Ka era, I do believe (although I'm not so sure about the 70-150/2.8). [Since I have only recently entered the world of "modern af bodies" (the DS), and since I have never really used any "program" modes on my LX's (of course - <g>) or on my Super A's (I've used manual and aperture-priority modes all the time), I never had a need to use the Adaptall 2 Ka version - the K version was all I ever used.] In the meantime, I apologize if my recent perhaps overly dogmatic statement might have been stated prematurely (in that I probably should have verified it first before posting it). [By the way, if anyone wants a Nikon Adaptall 2 mount for free - just pay the shipping - I've got one - it came with one lens or another, and it's just sitting on the 70-150/2.8, and, being a Nikon mount, it's kinda weird - you have to screw the Adaptall mount onto the lens clockwise, being careful to not at the same time un-screw the lens cap counterclockwise - <g>.] Fred
