Supported A-mount Lenses

The SAM and SSM lenses support auto focus when used with the NEX camera and the LA-EA1 Mount Adapter (sold separately).
Note: This feature also requires a firmware update for the NEX camera.

SAM Lenses

  • DT 18-55mm F3.5-5.6 SAM (SAL1855)
  • DT 28-75mm F2.8 SAM (SAL2875)
  • DT 55-200mm F4-5.6 SAM (SAL55200-2)
  • DT 30mm F2.8 Macro SAM (SAL30M28)
  • DT 35mm F1.8 SAM (SAL35F18)
  • DT 50mm F1.8 SAM (SAL50F18)
  • 85mm F2.8 SAM (SAL85F28)

SSM Lenses

  • Vario-Sonnar T* 16-35mm F2.8 ZA SSM (SAL1635Z)
  • Vario-Sonnar T* 24-70mm F2.8 ZA SSM (SAL2470Z)
  • Distagon T* 24mm F2 ZA SSM (SAL24F20G)

  • 300mm F2.8 G (SAL300F28G)
Notes:
  • Auto Focus function doesn't work for continuous AF on movie mode or AF-C on still mode, but it does work for AF-S (single AF by Photo key half push).
  • With an A-mount lens attached, the auto focus speed will be slower than when an E-mount lens is attached. It takes approximately 2 to 7 seconds (based on Sony�s measurement standard) and may vary depending on the subjects or brightness of the shooting environments.
  • To prevent Auto Focus noise being recorded, Sony recommends using a stereo microphone (sold separately) with stereo-mini plug (e.g. ECM-CG50).
