    So, if you could find a real Pentax Spotmatic motor drive (without camera) and a replacement bottom plate for the motor-drive camera, you could probably have the basis to pay a technician to attempt the mod.

    I'm not rememberin' real clear here but as I recollect the motor wasn't separate from th' body in that particular instance. Soooo ifn' my memories are keerect, ya'll may have to pick up a MD body t' get th' motor. Or not, it is my memory after all.

    Pentax Motor Modification

    In 1984 I bought a Konica FT-1. The FT-1 came with a combination split image/microprism focusing aid in its screen. This screen was not useful for macro work or with slower zoom or telephoto lenses. I brought the camera to Professional Camera Repair and asked them to remove the focusing screen and replace it with a Nikon E screen. This was a grid type screen made for the FE.FM series cameras. PCR did not like working on cameras like Konicas. In addition to paying for the screen I had to sign a release stating that if the camera was broken by the surgery, PCR would not be responsible. The work cost more than the camera body itself but was done expertly. I still have this camera and I have enjoyed using it for many years. When the modification was about 20 years old I had the camera completely overhauled by Greg Weber. If I'm lucky I'll get another 20 years if use out of it. At the time I had the modification done I already had many Konica and Konica mount lenses.

    If I had to make the same modification today I might not do it. The other 35mm cameras I have today with interchangeabe screens include two Canon F-1bodies, two Minolta X-700 bodies, A Nikon N2020 and a Mamiya NC1000S. It would be interesting to modify a Spotmatic and maybe have the only such camera but while a motor model is already available it doesn't seem worthwhile.

    NO all the Pentax Spotmatics and the ES models had removable motor drives, and at least from the Spotmatic, each new version had a motor drive model.

    I finally sent off an inquiry to the Pentax specialist, so I will see what he says.

    Bobby, are you sure? I ask because I spent some time in the spring of 1970 deciding which SLR system to buy into and unless my memory has failed badly -- this is possible -- the Spotmatics I handled then had no provision for motor drive and Pentax didn't offer even a power thumb. In fact, I don't think that any line of SLRs offered the simple power thumb you want.

    You should reconsider whether having your right thumb amputated is a good idea. You might need it for other purposes than advancing film. You might even have to use it for that.

    Bobby, I think Dan and John are right. The only motor drive screw mount Pentax's were specials with the drive permanently fixed to the body, definitely not detachable.

    OBVIOSULY-price is not a big part of the equation, but neither is it irrelevant.

    I actually thought about converting a Koni Omega back to have a motor drive (because the back was having advance problems). The circuit would be fairly simple if you are familiar with stepper motor control. The hard part is actually finding a place to cram the electronics, stepper motor and additional batteries into any camera you convert.

    This is as much as I found easily.

    The motor drive versions had the dedicated camera base-plate that said motor drive.
    This was the part that PCR would obtain,or create when they modified a non-drive version.
    When I bought my camera, they said they would have to special order the motor drive version and I was impatient, and very, very ignorant.

    Yes, you're right Bobby, I'd forgotten. These motor drive Pentax's were only available as a complete camera - motor drive & body, you never saw the motor drive body or the motor drive separately.

    Oooh man, wrong again, how will I ever live with myself.
    In my defense, In 30 yrs or better in the photo retail world I've only seen one of the spots with a motor & it was such an awkward beast I didn't bother futzing with it.
