With faster lenses at wide aperture (e.g. f/1.7), the AF indication is
not precise enough to give any good indication for very narrow Depth of
Field. With a careful focusing, I only get to focus where I want about
once every 3 to 5 shots at f/1.7 (perhaps I'm not the most talented guy
at this, though). The focusing screen is not very helpful with wide
apertures neither, at least much less than MF bodies focusing aids
(microprisms, split image telemeter). By the way, some people adapt
those MF focusing screens to the *ist DS/DS2, but this seems to alter
the metering in spot mode in random ways.
With slower lenses (and wider depth of field) it works like a charm,
like everything you mentioned.
Welcome to the list.

I am anticipating purchasing a Pentax Digital DS2 body.
Can I use my manual Pentax lenses I have collected over
the last 35 years on the DS2 body, Some lenses
are A-lenses, some are just SMC non A-lenses.
Can I focus these lens manually and observe through the viewfinder
that the lens is focused but even though I manually focus
still get electronic signal (light or beep ) that the lens is
focused?
Can I use all light metering functions ( matrix, center weighted,
spot )
with the A-lenses and some metering functions with the non A-lenses.
I am a new poster here.
Thanks in advance
