Can Pentax DS use manual K-mount lens? Would it have metering
functionality? Thanks.

Thanx. They are compatible lenses, not Pentax. One fit physically but
has no "A" setting. One has "A" setting but doesn't go fit in the camera
mount.


Be very, very careful with some of those "compatible" lenses; make sure
they are really K-mount compatible, not Pentax/Ricoh K/KP mount. If you
mount a KP-mount lens on a Pentax AF body it can get jammed on.


It says P-KA. It works in the K-1000 but not the Ds.

You may find some non-Pentax lenses don't mount on the DS
because the metal tab that guards the aperture actuating
lever is too deep and fouls the body. You can often remove
this (or modify it) and the lens will then work.

I've never heard of any Pentax lens being incompatible for
any reason though.

I did that to one lens, see above.

Yes and yes. Some details he

Thanks for the link. I got the lens without "A" setting work. Push the
AE-L button and the camera sets the shutter speed. No exposure reading
though.


What do you mean by 'exposure reading?' You set the aperture on the
lens, the camera set the shutter speed which is clearly visible in the
finder. To find out what shutter speed to use at a different aperture,
change the aperture and press AE-L.


I think this is how it works. At least it can meter.


Yes, in spot or center-weight mode. It can also tell you when the
subject is in focus.


The exposure metering. It doesn't give you a +/- number to tell you how
far you're off from correct exposure (0) when you put a non "A" lens. It
just sets the shutter speed for you.

Will not tell you that it is off because it meters correctly.

But if you adjust the shutter, it won't tell you how far off you are
anymore. A bit frustrating. I think I admire Canon's ease of use with
the EF lenses. No confusions.

We are talking about fully manual lenses here, all auto apperture lenses
work as they always did.

But we are taking about light metering. I guess you don't get continuous
light metering with manual lens. You do with K-1000. You change the
shutter speed and the needle reflects the changes.

Use the DoF preview lever, that also activates a display in
the viewfinder showing +/-3EV error. Adjust until it reads
zero.

Actually, it *will* show you the +/- over/under-exposure bar,
but only while you activate the DOF preview.

I don't mean to sound condescending, but if you double or halve the
metered shutter speed, you're off by +/- 1 stop.

As someone else pointed out: You can get a +/- EV by previewing DOF.
