M7 Metering problems

Just out out interest, my "in-box" M7 batteries
were "unmarked" brand (and good riddance to them).

William,
Unmarked batteries are not necessarily bad. Here in the US there are only 2 or 3 factories that produce batteries but a lot of brands, so buying a generic battery will get you the same product for less money. I could't say if this is the way things are done elsewhere. If your batteries that came with the camera were weak or dead they may have been old.

The dealer took my body back today - 3 sets of batteries since August 1st even with being extra careful - 1 set loaded during the blackout was dead by the next day.
With no ATM's and not enough cash for my whole office I took the M7 and looked for an open camera store - I shot everything I could knowing that if I found one open I was going to offer to use it as collateral for a cash loan for the people walking home from my office who felt that they might be able to get taxi drivers to stop at ridiculous prices. Absent a gold standard it was the first thing I could think of in an emergency.

Let's see how my new M7 is.
Thanks for the advice -

I just had the same experience as in my initial post when at top of the Empire State building yesterday. I had my M7 set to DX for film with ISO of 400.

After about 30 minutes in the cold (temperatures about -10 degrees celsius), my M7 stopped reading 400 ISO when switching back on, and camera registered an of 100 ISO. Even when setting film speed to 400 manually, it still read 100 to my immense frustration as I had to go to manual using my best guess.

Fortunately I had already shot 90% of what I had wanted to. Once camera was at room temperature for about 20 minutes, everything went back to normal.

It seems now with my first experience in Dubrovnik last summer, with temperatures of about 37 degrees celsius and high humidity, that the M7 can not take temperatures below 0 degrees or above 35 degrees celsius. This seems a bit light to me for such a costly camera.

Does this sound "usual" to anyone else shooting in moderately "extreme" conditions or does it come as a surprise?

Mark,

It sounds to me there was a disconnection to the film cannister for some reason, either that or moisture condensation, and the camera's program defaulted to 100 (as in the instruction manual when it cannot see the cannister contacts).

I would have selected manual ISO 400 to see if this rectified the problem. Try this next time.

Cheers, William
 
Thanks William,

I did do that yesterday, setting the film speed dial manually to 400, but when switching the camera on, I still got 100 as a reading.

Mark
 
Mark,

Sorry to hear this, in that case it could be that the selection dial has disconnected at the low temperature, in which case this switch will need to be repaired/replaced.

(My comments are only from my experience in writing embedded programs, not from Leica)

If the program is otherwise running, then the camera program is not accessing the information from the switch.

William
 
Thanks William

I've written to Leica and will see what they say

Camera is still under guarantee but always a hassle to lose a body for a number of weeks let alone having to pay shipping to Solms with insurance which usually runs 50-100 euros.

Whenever I have had to send a camera/lens back under warranty (only Leica or Contax) I have always returned it to the store purchased from and never had to pay shipping back to Contax or Leica.(I would refuse).On one occasion Leica were really slow and loaned me a replacement body.

Hi,

I have metering problem with my M7. I used Fuji Superia 200 color film and set DX auto mode. The camera showed 200 when started up normally. When I used the aperture priority automatic exposure mode (Set to AUTO), the right-hand trianglar LED is always blinking when the shuttle speed exceed 2 seconds.
I read in user manual to show that it only flashes when the shuttle speed falls below the slowest possible speed of 32s. But this LED is always flashes when shuttle speeds exceed 2s. Is it normal or something wrong with the metering devices in my M7. Please advise!
