Re: istD release with lens M

2003-08-17 Thread T Rittenhouse
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.

 You mean cannot meter at all, or that it meters as if the lens is set
 in full aperture, like in the MZ-50?

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.

 That's what I'm assuming.

Re: istD release with lens M

2003-08-14 Thread Arnold Stark
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.

Arnold

(still asking for stop down metering with all lenses not in A position, as available with fully manual lenses like K500/f4.5 or with M42 lenses)

Hi All,
Anyone hazard a guess as to exactly what the Release with lens M custom
function on the istD will do?
I realise speculation is fairly unusual on the list, but thought someone may
have a go.
Cheers,
Simon
PS - Maybe it sends a signal back to Pentax HQ when it's turned on, and if
enough people activate it they will release a DSLR with K/M compatibility.
