First off: I know very little about SLR cameras. I have read through some forum postings already but haven't been able to find answers to my questions. Part of it may be because I don't speak the SLR camera language well


I have recently been given a Pentax P3 camera that my uncle found while he was cleaning out his garage. It came with a Ricoh Rikenon 50mm f/2 lens attached, but nothing else.

I have since downloaded the manual (I love the internet), but it doesn't say which number batteries I need to get it going. Can anyone help me with this?

And am I correct in thinking that this camera has a KA lens mount?



The second half of my questions is about lenses...

About a year ago, another uncle gave my dad two older lenses for his camera. He has a different brand of camera, so I inherited those as well. I have been able to find good info on one lens, but not the other.

The first is a Sears macro 28mm f/2.8-22 lens. I found information that it has a Minolta MD mount. Is this correct?

The second I haven't found any info on. Around the lens it reads "Auto CPC Phase 2 CCT 200mm 1:3.3" and then what I believe is the serial number. I can find other CPC Phase 2 lenses, but I can't seem to find anything with f/3.3.


Will either of these two lenses work on my camera? I have loosely tried fitting them in with no luck. I'm already guessing the macro lens is a no.

The Minolta mount lenses aren't going to work with your P3.

If one lens is a Minolta mount, I would be surprised if the other isn't also. One place to look when trying to identify lens mounts:

And am I correct in thinking that this camera has a KA lens mount?

Yes. You can use just about any K-mount lens with this camera.

Lenses with limitations on the P3: Pentax FA-J series lenses will work in Program mode only, where the camera chooses all the settings. Pentax DA series lenses will also be program mode only, and mostly are not designed to cover the whole film area.

Other K-mount lenses are divided into two categories - lenses with an A position on the aperture ring (A, F, and FA series) and lenses without the A position. The lenses with an A position allow Program mode or manual mode. The camera body can't focus the lens, so even an auto-focus lens will have to be focused manually.
