200mm SMC M K mount

Vinny0077 · 10-21-2018, 10:07 PM

Hello I bought a used lense for my IST DS the lense is smc 200mm manual focus k mount lens. The lens firs in the mount just fine but when I turn it on it just doesn't seem to work at all I can't take any pictures with it. I am wondering if anyone could tell me if there is an adapter I could use or is the lense just isn't compatible with the body?

You have to follow these steps to meter with it:
How to use/meter Manual & M42 Lenses on all Pentax DSLRs (K-1, K-3, K-5, K-30, etc) - PentaxForums.com

To simplify it a bit, first, enable the custom function that allows use of the aperture ring, and then stop-down meter in M mode to get the correct shutter speed.
