I know it is a dead horse, but I think it was killed in the wrong way. The mechanical coupler is gone for good, and there's no reason for Pentax to reimplement it.
But a better solution could be achieved with software. I'd like to have, besides the green button behavior in M mode, a similar behavior in P: press the green button to get correct exposure. When the light changes, the camera modifies the shutter speed it had selected. If you move the aperture ring you're on your own. This would be a trivial firmware update, and would add a totally new mode for pre-A lenses. j On 10/8/06, Adam Maas <[EMAIL PROTECTED]> wrote: > William Robb wrote: > > ----- Original Message ----- > > From: "Adam Maas" > > Subject: Re: k10d and manual-aperture lenses? > > > > > >> In practice, the 'Green Button'/AE-lock hack on the DSLR's is simple > >> and > >> easy to use.
