My M5s need red dots!
Actually, taipei, yes, the TTL in the M6TTL means that the body camera has the circuitry to read flash intensity through the lens. See, most flashes of the traditional kind (say, Vivitar 283) are "automatic" flashes. This means the flash itself measures and controls the light output through a sensor on its body. When a camera has TTL flash sensors, it makes life easier as the camera, not the flash, regulates the output measured through the lens... exactly the same way the Nikon N55-N80 do.
The miracle here is that Leicas simply didn't have the circuitry before.
