When I'm using my old lenses that do not have an "A" setting, like
my SMC
200mm F4, on my *ist-DS, I gather that the "crippled mount" only

to shoot with the lens wide open.
Is it true that I can't use this lens in my *ist-DS at F22, because
the lens
doesn't close down during the exposure? I've been trying to figure
out how
to do this, but haven't been successful.
You can use any M/K-bayonet lens easily.
First go to the Custom settings Menu. Set "Using Aperture Ring" set
to Permitted. Leave that set all the time as it doesn't affect
anything else.
Lenses without an A mode are normally used in Manual exposure mode;
the DS implements a semi-automatic, aperture priority metering
operation:
- set exposure selector to Manual
- set desired aperture with the lens' ring.
- press AE-Lock button
The lens will stop down for a moment and the camera will take a
reading and set the shutter speed. All adjustments beyond that are
manual using the aperture ring and the thumbwheel for shutter speed.
If you hold the DoF preview lever, the display on the lower right of
the viewfinder will show you the deviation in EV from your metered
reading to the present scene and setting in the +/- 3.0EV range.
Other notes:
- These lenses will also work in Av mode, but only wide-open. All
other exposure modes default to Av mode.
- Metering patterns are limited to CW Averaging and Spot. If you're
set to Matrix metering pattern, the camera will automatically default
to CW Averaging.
- Aperture values will not be displayed on the LCD or viewfinder, and
will not be in the EXIF information.
- Only the center focusing sensor will be enabled for focus
confirmation.
