The M7 selects the shutter speed and is 99.999999% time correct . > You can take a picture at F1 in basically darkens at 1/1000 of a second > ( 8 > stops) . When in heaven's name would you use 1/15 of a second, an > additional 7 zones ?<<< Now you're really getting techie with this stuff. You're sure you're not explaining a 7 stage de-military zone are you? ;-) > A better question is how do you focus the camera in such dark light?<<< Now you know how good the view finder is on an M, most of them anyway. So all you do is focus on a highlight on the subject. There's always a highlight, actually after yer eyes become accustomed to the dark there's lots of them. Besides we're not talking about pitch black no light midnight in a coal mine. As there's always an essence of light, yep sometimes in a coal mine! ted
