I have both Pentax SuperProgram and Pentax PZ-1 and they are in one word -- fantastic! I have played with them for about few weeks with 2 rolls of film, not yet developed as I want to finish 4 rolls and put them in a CD in film processing.
Pictures of my Pentax SuperProgram and PZ-1:
Mine is silver chrome and black on the bottom. It looks darn good and I get it in marketplace from a great guy who has kept it in pristine condition, great salute to all photographers who keep the gear in pristine condition for others to inherit the Pentax fine jewels. Though the body is all metal and solid, I feel a bit not getting used to the shutter control as I can feel a bit of shaking in full press on the shutter. I am yet to see the outcomes in developed film. But the viewfinder is the BEST that I have used for manual focus, it has a big ViewFinder along with a split focusing screen. I have also purchased a winder to go with the camera. Unfortunately, not pictures yet for the combo. It is a darn cute gadget with 2 Frames+ per second on this film body.
The Pentax pz-1 and the better pz-1p should not be overlooked. Though the plastic body may not appeal to some when comparing to the K10D body, it does have a great impact to my liking when I use it. I have purchased and sold various copy of pz-10, pz-20 and none of them matches up to the pz-1 in terms of functionality, the overall ergonomics and the shutter sound in that old AF body is outstanding. It is an amazing body and its AF speed seems to do a equal, if not better, job than my dSLR with K100D. When I handle the pz-1 body, I immediately think that a lot of the current k10D are based on that AF body.
Thanks,
