As far as I know, that's only available with the new SF24. I don't think anybody's got that one yet. Here's what Dpreview says: "The modern metal blade slot shutter in the LEICA M8 enables very short flash synchronisation times down to 1/250 of a second. In addition, the LEICA M8 for the first time uses the new M-TTL flash technology. The special feature of this is that immediately before the actual flash illumination, a calibration pre-flash is fired. The TTL metering detects the light reflected from the surface of the subject, and determines the exact power requirement for the main flash. The smooth addition of the flash lighting power to the ambient light allows flash pictures that have the appearance of being under natural lighting. The "Auto Slow Sync" function permits the use of aperture priority mode in combination with flash technology. This provides a balanced background to the picture, even if the intensity of the continuous lighting changes. To achieve the correct lighting, an appropriately metered brightening flash is used. Depending on the desired effect or experience, varying lengths of lighting time can be set for the aperture priority mode. This can be input manually, or if coded lenses are being used, is can be determined automatically, using the proven rule of thumb "1/focal length = lighting time in seconds". It sounds fine unless you do the kind of photography that I do, where I try to be invisible. Nothing like 2 flashes to say "Hey! Look at the camera!"
