New [Old?] Pentax Gear

So I got a stack of old Pentax gear from Ebay.

Clicky for higher res

I got a fair amount of stuff with the package:

1. PENTAX ME SUPER WITH SMC PENTAX - M 1:1.7 50MM LENS WITH ORIGINAL CASE AND HANDBOOK
2. TOKINA TELEPHOTO LENS 70-210MM, 1:4-5.6 LENSE NO CASE
3. M - OPTIC LENSE 135 MM LENS, 1:2.8 WITH CASE
4. PROTONAR WIDE ANGLE LENS, 1:2.8 WITH CASE
5. CABLE SHUTTER RELEASE
6. SUNDRY FILTERS AND ADAPTOR RINGS

The items that interested me the most of the lot are the Pentax Opt. 50mm SMC F/1.7, the Protonar 28mm F/2.8 and the Pentax ME Super 35mm SLR.
I've given the 50mm a spin and (at least to me) is much sharper at F/2 than its modern brother the Pentax-FA SMC 50mm F/1.4, I'll post a comparison image later.

I have yet to mess around with the Protonar 28mm but I'll get around to it when I'm running around uni tomorrow, the ME Super needs to be sent off to be serviced and I'll need to stock up on film for it.
