Re: istD release with lens M
As I said in another post, the prototype we handled at GFM* seemed to be changing the speed index over several stops when Mark Roberts tried it with his K15/3.5. I did not notice that with my M50/1.7, but I had it in manual mode when I tried it. Not being an idiot, I did not think to check how it worked if you did something idiotic. In default mode it will not even fire the shutter. I was the one who reset the camera to fire with a non-A lens, but I did not think to try it in automatic with my M lens. In manual there was no exposure confirmation that I could see, and if I set a wrong exposure the result was obviously wrong. Mark will be able to tell you exactly what he did. Also, I do not a CF card, so everyone will have to wait for some of the other list members to get home to see images.

Re: istD release with lens M
I tried my M50/1.7 on the a prototype at GFM. The lens will stop down normally. Normal operation is not to allow the shutter to fire, the custom function over rides that idiot-proof feature. The camera can not meter in that mode because it has no idea what aperture is set on the lens, but everything else works.

Re: istD release with lens M
With the pre-production *ist D it was like this: Release with M lens + Lens not in A Position + Aperture priority mode = Full aperture during exposure, shutter speed selected automatically Release with M lens + Lens not in A Position + Manual mode = No metering but the lens will stop down during exposure.

If it is set to on then the camera will release, when a lens is set to manual aperture (aperture ring not in A mode, which is always the case for M/K lenses) otherwise the camera will not release.
