[Leica] I didn't know this...

[Robert Adler]

Just back from Yosemite (hopefully an image or two later...). Went with my
wife (Jane) and her high school friend who now lives in Australia. Her
friend went to Yosemite with her family every summer growing up (she
remembers the real fire falls off Glacier Point from the Glacier Point
Lodge (which burned down in 1969)... So it really wasn't a photo trip, and
the light was awful with the smoke from the Little Yosemite Valley fires
and temperatures during the day of 90deg...

Anyway, to the point. We saw the smoke from the fire in Little Yosemite
Valley and went to Washburn Point so I could take some pictures at sundown
+ to get the glow that appears after the sun goes down.

So my surprise was the 60sec exposure limit with the M. I became completely
baffled when I pumped the ISO up, put the setting on B and the exposure cut
off at less than 60 seconds despite holding down the shutter release on the
cable.

Going back to the room later and reading the manual, I found that the 60
seconds is for base ISO of 200. Pump the ISO to 400, and the time limit for
exposure goes to 30 seconds. Pump it again to 800 and the exposure time
limit drops again to 16 seconds; ISO 1600=8seconds and so forth.

So really it doesn't matter which ISO you use, you will not increase the
actual exposure at all.
Though I understand what's going on, I feel a bit cheated/mislead...

Just an FYI for M users who may not have discovered this.
