Leica M5 - power management

[Hassasin]

Going more at it before I loose steam. After two Barracks, a collection I will likely pursue just because I appreciate what it's done to photography and was hooked on looks/mechanics the moment I put my hands on first one, I now have an M5 coming.

Aside from looks, form factor, and some "dislikes" one can read about (I don't agree with most of them anyways), one thing I wonder about is battery life, given how meter is on when film is advanced until shutter is released. No idea how long a single battery lasts, surely affected by actual use. I'll be using MR9 voltage regulated adapter with an SR43 battery.

Aside from removing the battery when camera is put aside for a longer while, how do you manage or do you at all? Normally when shooting 35mm I'm used to advancing to next frame right afer a shot, most of the "greatest 35mm cameras" I have pose no issue with battery drain as they do have an off switch.

With M5 it seems a better way would be to advance film just before a shot is actually coming.

Or is battery draw rather insignificant/nil with lens cap on (and remove before a shot )?

I don’t have my camera in front of me but I believe that folding back the advance lever turns the meter off. My wife bought one of the first M5 cameras available and never had a problem with battery drain. However, since replacements of the battery compartment are no longer available, I remove battery before storing. I also use MR adapters.

All I see in manual is "measurement can only be made after shutter is tensioned, it is switched off after each exposure"

In my experience with the M5, battery draw is absolutely insignificant if you have the lens cap on or the camera is in a bag or something.

Don’t advance the film after an exposure. Plus, I don’t like the idea of the meter cell being exposed when changing lenses if you do advance after each exposure. It’s a matter of adapting to the camera. An excellent camera, too.

I have been using a M5 for 3 years without a battery replacement. I try to remember not to advance the last frame exposed and store the camera in a bag with or without a lens cap. I think I have a Silver Oxide bat.

Great camera to take photos with. The shutter speed and viewfinder my favorite attributes.

Hassasin is correct. I arrived at home and looked at my M5. Meter will be on as long as camera is cocked. Two days ago I put battery in my M5. Talk about a short term memory.

The resistance of the CdS cell is high when it is not exposed to light. With a tight lenscap on, there is very low current flow if any. Or don't advance the film until ready for the next exposure. I use lenscaps and my M5 batteries last a long time. (silver S76 cells, body modified to them).

On the M5, the cell retracts when the lens is removed. On the CL, the cell stays out with no lens.
