This one's tougher, but, considering the wide range of lighting situations in which it's happened, I shouldn't think it's the same shutter speed. Harder to know that about the aperture but again I suspect NOT, for the same reason. > How old is the camera? Have you checked/replaced batteries > recently? Purchased used about four-and-a-half years ago (so I don't know its real age); and No. I'll get some new batteries today. ERN

It _could_ be the ISO resistor. m Shel Belinkoff wrote: > > Hi Peter ... > > How might film speed affect the problem? > > "Peter J.

Re: Intermittent LX metering error
Hi, this was one of the symptoms of sticky mirror that I experienced before the syndrome became really severe. -- Cheers, Bob Thursday, February 26, 2004, 2:31:37 PM, ernreed2 wrote: > Anybody have an idea as to why my LX should produce the occasional, severely > underexposed frame (like no more than once per roll of film)?

They are rather prone to corrossion. A temporary fix can be had by turning the ISO dial from lock to lock a couple of dozen times. Were I you, I would get the thing in for service while Pentax is still servicing it. According to Pål Jensen, the new resistors are made of gold wire rather than copper wire, and are less prone to this problem. I had all three of my LX's done a couple of years ago. I am pretty sure that one of them displayed the problem after the fix, so i'm not sure if it is really a permanently repairable problem or not. It will show up on automatic most obviously, since the exposure goes all wonky, but I have noticed what I think is a symtom when shooting metered manual, with the occasisonal exposure reading that just doesn't make any sense.

As Bob W sez, it may also be early sticky mirror. William Robb

Thanks, all. I guess I'll be looking into repair possibilities. ERN

I have noticed this on my LX, but in my case the problem is quite mild. It only happens occasionally, and I can "fix" it by just wiggling the ISO dial a little. It is pretty obvious when it occurs: the meter indicates 1/2000 when I know intuitively that it should be something more like 1/125 or 1/250. Cheers, - Dave http://www.digistar.com/~dmann/
Re: Intermittent LX metering error
William Robb noticed a while ago that when using faster film, say 3200 or 800 with 2 stops of over exposure the meter automatic metering system in the LX will sometimes give extreme underexposure. I did a bit of experimenting and noticed the same behavior. When you would expect a seconds long exposure sometimes it will be much shorter. Shel Belinkoff wrote: Hi Peter ...

Re: Intermittent LX metering error
It's probably not the problem I suspected. My LX's will occasionally under expose on long exposures with 1600 and 3200 speed film. We had this discussion a few months ago. [EMAIL PROTECTED] wrote: Peter asked: What speed film are you using? Seen it happen with both 400 and 800.
