Originally posted by manufocus I finally got my hands on one of the infamous 500mm mirror lenses and I have to say I'm quite amazed! After all the bad press these lenses received Mine performs very good considering the price point and the difficulties of the Mirror construnction.
I use one of the User presets on my K30 with beefed up contrast and sharpness and more vivid colours. I also ordered two T2-PK adapters for comparison and one of them performed much better than the other one.
Now onto the main topic: I'm considering modifing the adapter to trick the camera into believing it's an a-mount lens to get full frame metering. Any thoughts on this and has someone already tried this?

if you are really into it, you can purchase solder in pins used for surface mount press contact connectors, they are all contained spring contact pins about 1.5-2.0mm long, and you drill and insert it into the mount where the A pin is located.
then you need to polish off the paint / anodizing from the T2 mount to make contact to the camera mount base.
the only risk is the pin is similar in size to the dreaded roicoh pin and it can get caught in the AF drive if you are not careful and keep the release button depressed for both install and remove
