Two weeks ago I was out shooting with my R8 and 90mm Summicron AA and 180mm APO Elmarit and in bright light with bothlenses somewhat opened, probably at f/5.6, the R8's viewfinder showed shutter speeds between 1/2000th and 1/4000th of a second. Had I been using my M6 TTL, what would have happened to my exposures if it, too, had discovered such bright light intensity despite its maximum shutter speed of 1/100th of a second? In other words, how far beyond 1/1000th of a second can the M6 TTL discern?

The meter would have indicated over exposure and the camera would have used whatever shutter speed you set it on.

I don't get it.. the knob only goes to 1/1000..

If you want to shoot in the same conditions with your M6 as you did with your R-camera, you'd have to use a ND-filter or load a slower film.
A neutral density-filter reduces the light and is useful if you want to shoot with large apertures.

Thanks, E.M. I forgot to mention that the high shutter speeds I experienced that day were due to my having loaded T-max 400 in my R8, so had I mentioned that my question would have been revised by adding what do I do if I've only got a 400-speed film with me because I forgot to bring, say, 100-speed film with me?

i read the m7 has accurate 1000 sec. exposure, but the manual shutter of the m6, & others
is 700.

i don't shoot rf
TBM, you only choices in that situation would be to:
1) Stop the lens down to a smaller aperture,
2) Load slower film,
3) Mount a ND filter.

or pull the film (underdevelop)

Or shoot a DSLR with fast shutter speeds and full auto exposure.

Thank you. Unless there is a worm hole or the time/space continuum ripped.

What's the true maximum speed? Quite possibly about 1/800 unless the camera has been recently serviced.

But does any of this careful precision actually answer the OP's question? I am dying to find out. Thread of the day indeed.

... 700.
... 1/800 ...
So about half a stop slow, that is, over exposed, when set to 1/1000. Is that then consistent for slower speeds, the effect of which would diminish as the speed goes down, or are they more accurate due to the way the shutter works?

That’s a 50htz telly, shot with a freshly rebuilt m2 shutter in this case, but I imagine the m6 would be the same.
The chap that sees to my cameras says he likes to set them at 1/850 because it’s less stressful, he didn’t say for whom.
I always think of the fastest and slowest speeds on a clockwork camera as being for emergencies only, but then I’m a “good enough” type anyway.

Dear Chris,
About +1/3 to +2/3 is normal with old-fashioned cloth focal-plane shutters at 1/1000 and (if I recall aright) ANSI standards allow for this with a +/- 2/3 tolerance (it's always +, of course) at 1/1000 and above. The standard drops to +/-1/3 at 1/500 and below. Personally I'd expect 1/1000 on an older Leica that's not been serviced to be around 1/800 (+1/3 stop) or at worst 1/650 (+2/3 stop); 1/500 to be at worst about 1/400 (+1/3 stop, though very probably 1/500); and other speeds to be as marked.
One of my old Pentax SVs runs about 1 stop slow down to 1/60 or so, i.e, every speed is half the marked speed, varying from 1/500 (1/1000) to 1/30 (1/60). The only accurate speeds on that camera are 1/15 to 1/4!
Cheers,
R.
