Very nice condition, all the accessories that would have been with it when new.
This is the full frame 1.7x teleconverter/AF adapter that provides autofocus capability with manual focus lenses. When used with autofocus lenses, the adapter performs the focusing rather than the lens. The Autofocus is screw drive, and it supports Tv or P exposure mode (in addition to M and Av), if the camera allows, but the converter does not transmit focal length and MTF information from lens to camera.
It supports A, K and M-series lenses with a maximum aperture of F2.8 or faster (there are some exclusions - so check the lens info before using). It performs better with fast apertures as the converter reduces available light by 1.5 stops. The converter has a limited adjustment range, so with some lenses you may need to manually turn the focusing ring on the lens closer to the desired focus point for the converter to be able to focus within that range. This generally applies to lenses with a long focus throw.

SMC Pentax-F 50mm f1.7
Fast, Compact, Autofocus, Full Frame, Excellent IQ - this one is in fairly good condition, cosmetically it has a few minor scuffs and marks, optically the coatings are good and the AF mechanism and aperture both positive and fast.
Price: £89 plus P&P

SMC Pentax-F 100mm F2.8 Macro
The first AF 100mm macro introduced by Pentax, no hood is neccessary due to the deeply recessed front element. The optical formula is so good that it was carried forward into the FA and DFA versions (not sure about the DFA-WR).
This version has the Focus Limiter (missing from most Pentax macro lenses produced later) which some fid particularly useful.
IQ is superb, build is excellent, it's a little weighty and bulky compared to the current version but it's nicely balanced in use, it's probably the rarest of the AF 100's!
Averything is working as it should be, minimal dust, positive aperture, great results. Cosmetic condition is pretty good, as are the optics and coatings.
