I've found a usability issue with my monochrom, actually it's the only a minor thing but it really tripped me up and left me with a bunch of overexposed images, so just a warning as some of you may walk the same path.
Setting the scene, previously used the press and hold of the shutter then dial the back to get exposure compensation. I was playing with the new firmware which allegedly fixes the hangs on soft+discrete release, so obviously set to soft and for some reason I set to not use the press hold and turn the rear ring for exposure comp.
So ... I went into the set menu, turned the exposure comp from 1 back to zero (was shooting some backlit subject prior). Basically Set -> Move to exposure comp -> rotate dial to zero. I then pressed the shutter to carry on using the camera, was on aperture priority in bright conditions, did not check my shutter speed. Discovered later when chimping that things looked too bright, sure enough over exposed. You have to press Set again for the setting to hold!!! Gah, lucky the images were nothing special.
Is it really September last year when I got my MM ... I can't believe it! Still the discrete release is not for me anyway, so in a little under a year, I found 1 minor issue with my camera!!! The refinement of Leica is so simple!
