There is a subtle refinement to the AUTO-ISO operation (from FW2.0) which is also easier to understand. If you set AUTO-ISO with Lens dependent setting of slowest shutter speed, the ISO is increased once the exposure slows to 1/focal length. Previously it was 1/focal length + 1 f stop. If that's too confusing you can just specify a speed instead of lens dependent. All of this requires coded lenses and lens detection selected ON, of course. Seems to work exactly as advertised in my M8.0 (aka Classic!)

Exp. Time In addition to the new firmware, I note that this area 2008-12-01-22:36:54 Steve Barbour: > http://us.leica-camera.com/service/downloads/rangefinder_cameras/m8/in > dex.html also contains downloadable M8.2 instructions, and I finally found a usefully-precise definition of "Lens dependent" for "Max. Exp. Time" in AUTO ISO, for all those of us who've stuffed the 2.0 firmware in an M8.nothing. I quote: If you select Lens dependent, the camera only switches to a higher sensitivity if the shutter speed would fall below the 1/(Focal length) threshold due to poor brightness, e.g. speeds slower than 1/30s for a 28mm lens. That seems close enough to what I'd want to happen that I might well consider using it, now that the behavior's been defined. -Jeff _______________________________________________ Leica Users Group.
