changing the aperture

I have a Pentax istD with Promaster 28 to 80 zoom. Although my zoom has adjustable aperturees, if I put it on anything but automatic, the shutter won't release. Is it possible to shoot pictures with this camera other than with the automatic aperture setting?

My boy has an istds but he's sleeping and it's in his room... I assume it's a similar process as on my K-x...
You need to go into the menu and set it up to allow use of aperture ring...

I don't have an istD, but with my other Pentax DSLR I must go to the menu and allow the use of the aperture ring. Check in your menu settings and look for 'allow aperture', or something like that.

Although I don't have the lens, I assume that you can just set the aperture from the camera (in Av or M mode). Am I incorrect in thinking that?

Pentax istD

thanks for the suggestions but so far I haven't figured it out. My menu doesn't seem to have an allow aperture in my menu. I've tried every setting but the shutter just won't release if it's off of automatic

There is an option, but you shouldn't need to use it as long as your lenses do have an automatic position, as the metering won't be right unless you use automatic. You should use automatic position on the lens, and let the camera set the aperture (or you choose it yourself, using the camera).

You have to set the Custom Function to allow shutter release when the aperture is set to something other than A.

In the "custom menu" there is a setting that needs to be turned on "set F other than A"

This is correct, the *istD terminology is not the same as other cameras.
