Is the Pentax 50mm an A series? If so, great glass.

The Ricoh 105 should be a very good performer too.

I have no experience with the others, but I would expect that Tokina to be worth every penny. Very highly reguarded lens.

The Rikenons might not be good for your camera (Ricoh K-Mount), I've heard pretty good things about the AT-X 100-300, though I've never used one, the Pentax 50/1.7 is a good optic, the 500/8 could be good, it could also be one best described by the words that cause the vocabulary police to have kittens with my posts. If it's a Tamron, it will be a good lens with strange bokeh, if it's one of the old Vivitar Solid Cats, it is an excellent lens with strange bokeh.
Anything else, all bets are off. Every man and his dog have made 500/8 lenses, mostly poorly.

The above are not to be construed as an endorsement for a particular lens sample, and presumes that the lenses are in good working condition with undamaged, properly aligned optics.

Pentax M 50/1.7 is possibly the sharpest manual 50 Pentax made, especially below f/4. Well worth $50

1 500mm f/8 lens - $50
I bought a Phoenix 500mm f8 new for $100.00, and if it's the same lens then it's really good for the $. But you'll still want something better right away.
The same lens was manufactured under several names, and is really a T-mount.

I'd advise saving the coin for something a little better.

I have no experience with the Rikenon lenses but I've heard good things about them. As far as the 50mm 1.7 goes, I have 3 -M 50mm 1.7 that I use on both of my MXs and my ME. I also have 2 -A 50mm 1.7 with one on my wife's Super Program and one to use on my k100D Super. The -M is an excellent lens both glass/construction and the -A is great glass but poor construction/design. This won't make any difference if you only use it on the A setting as I do.

I'd be interested to hear what people think about Rikenons. I picked up a v. cheap XR Rikenon 28/2.8 the other day, but haven't had a chance to try it out much. I did post a couple photos from it in the DCL club.

I only have experience with Rikenons of the M42 and Richoh Diacord variety.

I think the Diacord lens is slightly better than what's on the Yashica Mat 124G.

My two M42's (135/2.8, 28/2.8) I'd put a step behind most Takumars, they sharpen up as you close the aperture and are very well made lenses. I know the 50's and 55's are very good indeed. I'd place Rikenons - in general, specifics will vary - in with the major better 3rd party makes. (Often they were made by the same OEM) That 105 macro should be a super lens.

With the K mount, the PROGRAM capable Ricoh lenses may pose a problem, but as far as I know the non PROGRAM ones should mount fine.
