I am writing to you in regards to digital cameras. My inquiry is about adapting screw mount lenses to Pantex digital camera bodies.
My present camera is a “Pantex Spotmatic II”, screw mount (yes an oldie). My questions are regarding weather on not my lenses would be able to be adapted to a new digital body, I am thinking of a “K110D or K100D” system. The cost is one consideration if it could be done. I would like to get into digital, if it is with my lenses and a new body or just a point and shot.
Inquiry
- Is it possible to adapt screw mount to bayonet mount bodies.
- Would the aperture setting work with the Digital body.
- Would the metering system of the Digital body work with my lenses.
Thank you

jimrodman@sympatico.ca It would be interesting to know what your lenses and picture taking preferences are.
One thing you need to consider going from film to digital is that the pentax DSLRs have a sensor that is smaller than the frame of a 35mm camera.
your film camera has a 36mm wide by 24mm high frame. The DSLR has a frame 24mm wide by 16mm high
therefore your shots will be "cropped" or have a narrower field of view. This will cause you to perhaps purchase one additional lens (i.e. a wider lens than yoou presently own).
You can probably get by with a Kit lens in the 18-55 mm range.
Also note that with your screw mount lenses, the easiest way for you to shoot is in Av mode, and you would focus and compose with the apature wide open, and then manually stop down the lenses for the exposure you want.
Also note, while you hear people on the forum talking about the magical "green button" it only exists on the *istD, K10D and K20D, and is really more practical for K mount lenses not as much for screw mount. Screw mount, as I said work just fine in Av mode, because when you turn the apature ring you stop the lens down. This is because there is no automatic apature functionality on M42 lenses with the K mount adaptor.
