Lens Mounts

Hi everyone,

I'm new to the forum, and also new to the world of Pentax cameras. I bought myself a second hand K-M DSLR, and have been looking online for a macro lens suitable for what I'm told is a KAF2 mount on this body. The only lenses currently available in my price range are all K mounts. I know this might seem a bit of a daft question, but does anybody know if these are compatible, with or without an adaptor? I'm so confused!

Thanks guys

Everything you need to know should be here - it's also a sticky post on this section:

Autofocus is not really important for a macro lens. It seems like a good idea, but at higher magnifications, it has trouble locking on the exact thing you want. If you are thinking about subjects smaller than a US quarter (or maybe a euro) then AF is less important.

Your KAF2 mount will fit any K mount lens without any adapter.

Any K mount should work, just watch for the Ricoh pin on some of the old Ricoh lenses.

Thanks everyone, you've all been a great help. Found an awesome lens on eBay, so I have my fingers crossed that somebody else don't put in a big bid!
