LX Issues

So, I got my LX overhauled last year and have barely put 5 rolls through it. The last two rolls (in the past week-and-a-half) -- for a few shots the mirror would hang up and then come down when I took the camera out of the auto mode. This can't be sticky mirror already, can it?

I had the same issue on one of my LX and that was right after it came back from Eric. Then the problem seem to have gone away then it came back.
I would also be curious to know about this in more detail.

Cheers,

Could be a dead battery. I know, that at least some LXes behaved like that (mirror-up and shut down).

I'm guessing it's battery problem too. Change the batteries and see how.

Another problem about LX (and MX) camera is that the batteries run out of juice too fast. Hope yours isn't this case.

Another silly question, but was the lens cap on or were you indoors with the ISO set low and the F-stop small? I've had this happen and it was just the camera attempting a very long exposure with light conditions that would legitimately indicate that kind of exposure.

Nope -- lens cap off, focused on a subject and attempting to shoot in daylight around f1.7-f2.8. Should not have been an issue.

I haven't tried to replace the batteries yet. I didn't have anough time to dig them out over the weekend.

Hey, you, btw.


In case it helps, one thing I find about the climate down here is that it really does seem to exacerbate lube-related problems that one might not notice elsewhere. I'm just starting to get in the habit of checking even long-trusted lenses for snappy irises.

Recently I saw a very desirable Pentax lens at KEH for a bargain price due to a claimed sticky diaphragm.
It would have been a very good buy even including Eric's repair cost, so I went ahead and purchased it.
But when it arrived there was no problem - diaphragm isn't sluggish; it opens and closes in a snappy fashion.

Now New York can't match Georgia temperatures, but our humidity is world class. I'll check it again in July...

Hey you as well -- it has been too long.

I doubt that it would be a heat/lube issue as I was having the issues when it was a good bit cooler and when I was in New York a couple of weeks ago. I'm digging out my batteries tonight!!!

Just to offer up a shred of closure -- I tried some batteries that I had on hand and the camera worked a bit better, but still "stuck" a couple of times (dry-firing), but they were old new batteries if that makes sense. I bought some fresh ones a shot a roll yesterday and had no hang-ups and the speeds sounded good. I think that it was a battery issue. I will be fully convinced when I get back a set of beautifully exposed photos tomorrow.

Cheers,

Adam

Dry firing an LX in auto will lead to all sorts of weird results.
I'm just sayin', so don't be startin' a fight.

Yeah -- I was looking primarily at mirror operation. The speeds in auto seemed off, but I remembered that the LX meters off the film in auto, so I paid attention once film was in the camera & it seemed fine.

No film in an LX poses the problem of a difference between the meter and the actual exposure timing due to metering cell picking up the light off a patterned portion of the shutter. But this only occurs before the mirror flips up out of the way and the shutter opens, then the actual exposure timing is the silicon cell looking at the pressure plate (which is black and doesn't reflect light as well as an actual film emulsion).

However, the problem of the shutter hanging until the shutter dial is moved off "Auto" is common to a dead or cold battery. The cold battery can be resolved with the remote battery cord (a dummy plug with a cord that goes to a battery in your warm pocket).

Ah -- that cord is an interesting solution for cold weather. Not much of a problem here, but a novel idea to me.
