Hello Pentax 6X7 Friends


I am new to this forum and I am looking for help with a Pentax 6X7 Camera and lens (75mm and 145mm).

I have replaced the battery (6V) Kodak...Battery Check light is "OK". But I can't seem to get the shutter to 'fire".

Any help with this camera would be appreciated.

Hello and welcome to the Pentax Forum.

Unfortunately the 6x7 camera is not designed to fire without film loaded like a 35mm camera.

Here is a copy of the 6x7 manual with instructions on how to do so:

See pages 4 & 5.

Rotate to the "Left" ? -Counter Clock Wise...

Thank you for the 'reply'. When it says to rotate the knob to the 'left" .

Is this Counter Clock Wise ? I tried rotating this knob, but it seems to be spring-loaded and always springs back to "0" (Zero).

I must be doing something wrong.

Thank You for your help.

You need to hold the counter in place at #1 while you close the back again.
Use a work-around if you don't have the shutter cocking key. Open the camera back by sliding the release tab. Manually turn the exposure counter dial counterclockwise until the film counter indicates 1 or a higher frame count in the film advance window. Close the camera back while keeping your finger on the exposure counter dial. Rotate the film winding lever until the shutter is cocked. The camera shutter can now be fired, because you've fooled the safety interlok into thinking that there is film in the camera.

OK, OK, I gave in.

I just ordered a P67 Mirror Lockup model with 75 f4.5 from eBay Japan.

I have had a P645N for a few years, really only using it seriously for the last few months and now I also have a P645D. Even more recently I bought a P67-645 adapter (genuine), 105/2.4 and 55/4...both latest models. I have liked what I've seen with these lenses and of course the relatively low prices one can by them for.

I'm now going to sell my P645N, 45/2.8, 75/2.8 2x converter and probably even the 200/4.
