M240 focus crashing

[Marct40]

I have had my M240 for a few weeks now, all is good except on occasion the centre rectangle focusing point doesn't have the split screen after turning on and off the camera( I can't focus it). It does always happen and is cured by taking the battery out and plugging it in again. Lens is a new summicron 50

I am not sure what it could be anyone else have this problem?

Make sure the small window in front of the camera (just below the shutter speed dial) is not obscured. Fingers and camera straps have the nasty habit of resting in front of that window.

I suspect that taking the battery out changes the subsequent position of your fingers gripping the camera. Ultimately it is 'finger trouble' and can even happen to experienced Leica users if they have gloves on and accidentally cover the window, although with experience you know what you've done. Try it yourself and you'll see what happens, look through the viewfinder and put a finger over the little window on the front and the focus patch will disappear

Further to the excellent advice on the cause written above, the battery plays no part in the presence of the rangefinder patch, which is a mechanical-optical device and not electronic at all. Here is a picture of how it works. (Look below "Where is my mirror?"). Your finger is inadvertently blocking window B.
