Of course, John, you are right. Funny, somehow I managed to make myself believe it was working. I even shot some frames around today's pic in my photoblog in this mode: http://photoblog.jbuhler.com/index.php?showimage=179 (istD, K24/3.5) I suppose that they ended up being usable because I was

Juan. When John first got his D, I drove down to take a look at it and brought a couple of K-mount lenses. At that time John was still learning about the camera, and, of course, I knew even less about it. I don't think the green button technique was even known at that time. Anyway, we fiddled

It would only take a simple firmware change to make the camera work this way though... j I suggested that to Pentax in one of my many customer feedback and support inquiries. It could be done in at least two ways: - Allow manual setting of the aperture when in Av. It's the user's

That's pretty much how it happened. The green button technique was not only unknown at the time - it wasn't even available. In fact one of my posts shortly after that outing described what we had discovered, and even described a hypothetical change to the firmware that would make K/M lenses

So I'm curious... I read the Pentax DSLR manuals regarding use of old lenses on the *istD/DS/DL, but they seem kinda vague to me, and not very confidence-inspiring for using old glass on the new bodies. Exactly how are the old lenses used on the DSLRs? --- John Francis [EMAIL PROTECTED] wrote:

It's fairly simple actually, you set the camera to allow shutter release with the lens set to other than A Set the mode to manual, (M). Select the shooting aperture and then either compose and instantly meter the scene by pressing the green button, on a D or the exposure lock on the Ds or DL.
