M6 and M6TTL
Is there a difference and if so what is it? I'm at work and this kind of came up.
Thanks,
Thomas

The TTL version has TTL flash capability with Leica SF20/24 and certain SCA-adapters. It is also 2mm higher due to more electronics. All other specs are the same except for the shutter speed selector that goes the "wrong way" according to many (in the direction of the light meter arrows in the finder).

All that EmilGil said plus the shutter dial is bigger than on the M6 classic. Someone says that it's easier to change speeds on the TTL, because it protrudes a bit over the front of the camera and you can turn it without moving your right hand away from the grip.

The M6 has a shutter speed dial rotation that is the same as all preceding M bodies. The M6TTL reversed that direction as have the M7 and M8. Many experienced Leica hands prefer the "old" way. The change was done for ergonomic reasons.

Other differences:
The light meter display of the TTL has 3 leds - 2 arrows with a dot in the center (like this... > * < ) The dot alone indicates a correct exposure, while a display showing the dot and one arrow indicates a 1/2 stop under or over exposure depending on which arrow lights up. The M6 just has the arrows, when both light up, exposure is deemed to be correct.
Also, the TTL's light meter is one stop more sensitive.

One more thing -- he M6TTL meter has 1EV more sensitivity than the M6, as I recall (I don't have the reference book with me right at the moment).

My M5s need red dots!
All of the above applies and it's true. Long live the M6TTL!

...and the battery life on the TTL is around 40% less than on the classic, due to the extra LED and the increased complexity of the electronics. Not a biggie, but worth mentioning
