No idea. I've had two finders. The refconverter A, which has switchable magnifications and shows an image right way around. I purchased it originally for use on a Ricoh XRM, and later used it on a ZX 5n, LX, *ist, PZ-20, K-10, K-20, and now K-5. I also had a Pentax right angle finder for my original Spotmatic. The eyepiece of the early Pentax models was smaller, so this unit could not be used on later Pentaxes. It did not have a higher magnification and the image was reversed left-to-right. Another annoying feature of both these devices: aside from not having some means to lock the focus for your eye, there is no index with tick marks, similar to that on one eyepiece of most binoculars, that would allow quick resetting. You must attempt to focus the lens, then adjust the refconverter if the image isn't quite sharp, then go back to focussing the lens, OR bring up the composing grid first and focus the refconverter on that. I found it very difficult to focus the device on the faint autofocus point indicators. Difficulty with this device is why on several occasion in the "Dear Pentax" discussion (grousing?) I've wished for a tiltable LCD screen, and better still one that could be unplugged then reconnected by a wire. After two hip surgeries, I cannot easily get down for ground level macro work as once I did without thinking it a remarkable ability. ---------- Post added 03-31-12 at 09:09 PM ---------- Second reply. I just went onto EBAY and found a Refconverter A listed for over $500!!!! Also, there were a couple of very early Asahi Pentax right angle finders, earlier than the model I had for my Spotmatic, that DID have binocular style diopter tick marks for setting the focus. Why ever did they drop this useful feature on later models??? Remember, these will not fit any Pentax autofocus SLRs because Pentax widened the eyepiece sometime before they introduced the LX.
