It's basically same as regular vanilla XR 50/2 lens, with motor and foto cell for autofocus and light meter added to drive and run the AF. It will focus automatically on manual bodies with apreture controll. Not really usefull today.

I have one of these but I never thought to use this on my K30 because of the overhanging pentaprism (I think a lot of DSLRs may struggle to fit this - has anyone tried it?)

It might have the infamous ricoh pin on the mount. So I would be careful with that stuff on Pentax dslr's.

I have the manual version and it is a nice older lens. No clue if the AF is any good though. I would just say no and find a manual f/2 Rikenon for 15 AUD and use it with green button metering. Works great for bokeh and portrait style images.

An interesting curiosity, it adds AF to a Pentax K manual focus body.
I had one but never tried it; it was destroyed in the flood from Sandy.
Like the XR Rikenon 50/2 lens image quality should be quite good.

I had one briefly and although image quality is better than SMC-A 50m 2.0 , its still not up to par with a regular Ricoh Rikenon 50mm 2.0 or the "P" 50mm 2.0 version.
Although an interesting lens , unless you shoot film or collect Ricoh's , its probably best to pass this one.

I only used it on Ricoh and Pentax film bodies.
