It worked! I have played around with adaptall mounts, but this is my first TX. I figured that I had to push the button and turn, but didn't know where the aperture ring had to be set. I had also seen from your pictures that the ring with the block did not come off with the mount, so I was trying to turn the mount only. There isn't much to get a hold of, so I wasn't sure.

I will disable the Manual switch and find a use for this good looking glass.

Again,
Many thanks.

You are very welcome Jim. That lens if it is as good as mine will be quite sharp...watch for some CA if you shoot into bright light or have light highlights. Other than a little CA it is one of the finest 200mm lens out there in manual focus form.

CA is Chromatic Aberration. PF is Purple Fringing and it is a type of Chromatic Aberration as well. For an explanation go here....

Pentax SMC coatings are very good at controlling most CA but Older lens like the Vivitars are not as good with it. It can be controlled some by how where and when you take the photo.

My laptop crashed last night. I can only get it to run in safe mode.

*my laptop*



So im gonna try a clean and fresh restart. then have to reinstall all my video/audio multi tracking software and plugins then onto CS4 and light room 2.. Then i can get back to work.


Worst of all, i think i lost the novel i was writing, 50,000+ words into it.
