Thanks Erik. Does the older adapter allow auto focus with Alpha & Minolta AF lenses as well (albeit maybe slower?)
The la-ea1 will only autofocus Alpha mount lenses that have a built in focus motor. Here is the list of Alpha Lenses with SAM or SSM:
Carl Zeiss Distagon T* 24mm f/2 ZA SSM (36 mm - equivalent focal length on the NEX)
CZ Vario-Sonnar® T* 16-35 mm f2.8 Zoom SSM (24 - 52.5 mm)
CZ Vario-Sonnar® T* 24-70 mm f2.8 Zoom SSM (36 - 105 mm)
Sony Alpha 30mm f/2.8 Macro Lens SAM (45mm)
SA 35 mm f/1.8 SAM (52.5 mm)
SA 50 mm f/1.8 SAM (75 mm)
SA 85 mm f/2.8 SAM (127.5 mm)
SA 300 mm f/2.8 G SSM (450 mm)
SA DT 18-55 mm f/3.5-5.6 Zoom Lens SAM (27 - 82.5 mm)
SA 28-75 mm f/2.8 Zoom Lens SAM (42 - 112.5 mm)
SA 55-200 mm f/4-5.6 Zoom Lens SAM (82.5 - 300 mm)
SA 70-200mm f/2.8 G SSM (105 - 300 mm)
SA 70-300 mm f/4-5.6 G Zoom Lens SSM (105 - 450 mm)
SA 70-400 mm f/4-5.6 G Zoom Lens SSM (105 - 600 mm)
Certain Sigma lenses with HSM will also work, but the results have been sporadic. My Sigma 70-200 F/2.8 works on my NEX-5 with the la-ea1.
However, with the peaking feature, MF is so easy, it's almost faster to focus that way than to wait on the slower CD-AF...
