Adaptall 2 mount help please

Can I mount an adaptall 2 lens with M42 mount onto my K-x with its Pentax M42 to K mount adptor fitted? And how would the lens work? The lens is a 28mm 2.5.

Or do I need a PK or PKA adaptor? The PK mount is cheap on ebay, but the PKA seems rare and expensive but will enable more functions ( me a begginer more functions is good ).

Also are there any issues with the cheap ebay mounts as there are with the M42 to k ones?

1) yes, you can mount a M42 Adaptall via the K adapter. The M42 adaptalls however lack an a/m switch so you'll be limited to open aperture only, unless you modify the adaptall to hold the pin in.
2) Either a K or KA adaptall work, the K works like a M lens - manual stop down metering but auto aperture - and the KA works like an A lens - supports the auto exposure modes.

Thanks Nesster, don't think I'll be modifying anything , but at least I know I can put it on my camera for a play to see if I want to spend $ on an adaptor.

What Nesster said...

The cost of an Adaptall-2 M42 + M42/K adapter would be more than just getting the standard Adaptall-2 P/K and would offer no real advantage in terms of usability. According to your profile, you shoot with a K-x. On that camera, your best meter accuracy is in M-mode, so the a K-mount is an advantage over M42.
