does not work with CDAF
has an extendable Leica M mount controlled by an internal motor powered by the camera battery which responds to electronic communications with the camera to provide up to 4.5mm z-shift resulting in AF in less than 1 sec and supports both AF-C and AF-S modes (but no AF-C in video mode) and supports Wide, Center, and Flexible spot.
does not support Face Detect AF or Eye EF.
set the focus ring at infinity focus and use the Techart PRO for focusing
for close up shots, you can set the focus ring at closest and use the Techart PRO for focusing where it can act as a 4.5mm extension ring to get even closer than normal
for longer focal length lens, you will need to coarse adjust the focus ring and use Techart PRO for fine focusing
can also further adapt other lens mounts with longer flange distance such as Canon EF/Canon FD/Nikon F/Contax CY/Leica R/Olympus OM/Minolta MD/Pentax PK/etc to the Techart PRO adapter via an additional adapter such as AR-LM, LR-LM, FD-LM, EOS-LM, AI-LM, MD-LM, EXA-LM, OM-LM
weighs 133g, max. supported weight of lens 700g BUT you can use larger lenses if they have a tripod mount and you use it on a tripod, in this case, the AF motor only has to push the camera and adapter and not the lens!
Techart PRO allows you to save 10 sets of lens data, including focal lengths and aperture values, via their complementary mobile app. The camera body will be able to make corresponding adjustments including sensor based IS.
No electronic communication with lens, so NO aperture control and no OIS - user can use the smartphone app to set the lens EXIF info for the camera but currently aperture cannot be set for EXIF so camera displays f/2 only irrespective of lens aperture
the adapter will not fit when using a Sony battery grip on the camera
AF is faster with aperture wide open, thus if shooting at smaller apertures you may need to AF at wide aperture then stop down the aperture
AF is fastest with lenses less than 300g and becomes slower with larger lenses but will AF up to 800g lenses reasonably fast
can turn OFF the adapter by setting camera to MF mode
if becomes unresponsive in AF mode, made need to dismount and re-mount adapter to camera
Bluetooth for firmware upgrades and smartphone app communications
$US379 from website or $AU499 on Ebay
other lens mount to Leica M mount adapters on website for $US70 (more for medium format), but it seems these can only be purchased at same time as the AF adapter although compatible Fotomix adapters are available on Ebay
as the base sits BELOW the base of the camera, you can purchase an L plate for the camera to make it sit level with the camera L plate base
