Does your K1000 light meter do this...?

I'm shooting in a relatively deep-shade place, say a gorge with a stream. I want a long exposure. The meter reads ok at any aperture or speed, down to a speed of 1/2 second. Then if I turn the dial to 1 second, the needle shoots way up to where it would be on "B" -- even if 1 second would have been the right exposure. So I have to go back to 1/2 second, find the right aperture with that, then extrapolate from there. I mean, I don't mind doing that; keeps me thinking about the process which I enjoy, & I often calculate several seconds' exposure at f22 based on what Mr Light Meter told me for, say, 1/2 at 5.6. But let's suppose that 1/2 at 5.6 is an ok exposure. Then 1s at f8 should be ok too. But when I turn the shutter speed dial to 1s, the needle goes all the way to the top. If I ignore the needle & take the shot, it will be ok.

The meter also kind of packs up at twilight. I mean, there should still be enough light to get a reading, but it becomes much less sensitive, or something. I always wind up having to calculate from, say, 1/2 or 1/4 at 3.5. Occasionally then, as the light goes, the 1s reading works without sending the needle to the top. But that's just before it quits entirely.

I've never used another one, so I don't know if this is how the K1000 meter is supposed to act. I'm just used to it. But I've often wondered if this is common or it's just my camera. So finally thought I'd ask.
Anyone?

Mine doesn't do that. What happens in bright light when you go to 1000th? Do the click stops correspond to the markings on the shutter speed dial?

I have an SP1000 which I beleive has the same meter as the K1000, so hopefully my experiences will be relevant.

On the SP the meter acts as you have described, anything 1sec or over causes the needle to rise to the top.
And in darker areas it becomes rather useless. (granted, that's with an F3.5 135mm lens on it)



Basically, it sounds like the meter is acting normally for you. The only strange sounding bit is how on 1sec it will sometimes work.

Perhaps try a new battery? maybe the one in there is getting a little old and not giving an even charge?

According to the K1000 manual, the light meter can read between EV3 - EV18 at ISO 100. You can encounter EV3 at twilight. So exercise caution.

What he said. What's more, the issue of meter sensitivity becomes even more important if you are using stop-down metering with an adapted M42 lens.

And make sure you are using the proper voltage battery. It can get confusing putting batteries in these old cams as some aren't available anymore or they've changed the numbers...

Heh. I don't even know what an "adapted M42 lens" is, so I guess I haven't got one! They are all Pentax SMC-A, -F, or -FA, & one Tokina K mount. The battery is ok.

Everything works, & I have no problems at 1/1000th. (why?)

Those would be threaded lenses that screw-on like the Takumar lenses used on a Spotmatic, for example.

Just wondering whether the shutter speed dial is out of alignment.

If you're still getting good shots, I wouldn't stress about it. I used to do a lot of low-light photography with my K1000 (still got it and it still works), and I also used to play with shutter speed/aperture changes to determine the correct exposure. This was when I was doing my own B&W processing and taking 20-30 minutes to set up a shot. Good fun!
