Sony A-Mount to E-Mount Lens Adapter (Black)

Hello, B&H sells two adapters that let you put A mount lenses on E mount camera body. One of them (LE-EA 3) has a motor that will drive autofocus. The Sigma 17-50mm lens is a autofocus lens, so the two paired together will do autofocus. Now if you pair the LE-EA3 with a manual lens, to my knowledge you will not have autofocus. Hope this helps.

Does the focus magnifier also work with third-party lenses like the Tamron SP AF 70-300mm f 4.0-5.6 Di VC USD in A-mount?Thank you so much!

This adapter will allow autofocus for those Sony or Minolta mount lenses which have a built in AF motor.

Yes, the Sony A-Mount to E-Mount Lens Adapter is compatible for use on the Sony Alpha a6000 Mirrorless Digital Camera, and would be compatible for use with both full-frame and APS-C A-mount lenses.

The Sony DT 55-300mm lens is an APS-C format lens and has a smaller image circle than a full frame lens. There is vignetting because of the lens.

I can't remember if Ssm is the autofocus motor or not. if it is it will work fine but it might hunt in lowlight. I use my adapter for my Tamron 150 to 600 and the lens focuses fine in the daytime but I haven't gotten a chance to track birds in flight with it yet. If you really depend on fast, reliable autofocus then I'd go with the e mount 50mm from Zeiss or the cheap Sony 50 if you don't need 1.4

No, there are no adapters that will allow one to mount E lenses on the Sony A mount cameras.

The LA-EA3 is compatible with the NEX-7. This adapter can be used with any E-mount camera regardless of sensor size. It does have an aperture mechanism to support auto exposure, so you can shoot in full manual, aperture priority, shutter priority, and auto. With this adapter, Sony SSM and SAM lenses will retain autofocus for still shots. So, the 55-300mm lens would autofocus with the LA-EA3.
