I've got a Takumar (Pentax called all their lenses Takumar when this one was new) 135 mm..f3.5 screw mount...from the mid 70's that I bought new. Always liked it on my Pentax ES 11...wonder how it will do...when I eventually get a digital Pentax SLR ?

How do I adapt a screw mount to a digital SLR like a K10D...do I need some kind of adapter..are they cheap or pricey (adapter) ?

You can probably get an adapter for about 20$

Make sure you get the right model, and a metal one, not plastic.

This is the type you want: it'll function 100% fine with this one, infinity focus and everything.



This is the type you DON'T want: because of the flange thickness you will lose infinity focus.





The way to meter is to put the camera in Av (or M if you want it manual), and just stop down the lens on the aperture ring.

any of the adapters from adorama or B&H are good. runs about $18 delivered.. i have a kalt from B&H that works just fine. i don't need the tool to mount/dismount because my fingernails are like steel..

I would probably need the tool as my finger nails are not that strong.

Doesn't take much to get them off...I've used a coin sometimes and one of my keys at other times if I didn't have a tool handy!

Thanks for the hints, regarding 'alternate' tools.
