Sony LA-EA3 adapter

Sony LA-EA3 adapter (adapts Sony Alpha or Minolta MAXXUM AF SLR lenses to NEX, about $200).My biggest source of support is when you use any of these links, especially this link directly to it at Adorama or directly to it at Amazon, when you get anything, regardless of the country in which you live. It helps me keep adding to this free website when you get yours through those links — but I receive nothing for my efforts if you buy elsewhere. Thanks for your support! Ken.

This adapter lets us mount Sony Alpha or Minolta MAXXUM AF SLR lenses on the compact Sony NEX cameras, especially the full-frame A7.

For autofocus, you really want the more complex LA-EA4 which has a motor to drive all AF lenses. This simpler LA-EA3 has no motor, and merely passes-through the electronic AF connections to allow AF lenses with their own interal AF motors to focus.

THIS LA-EA3 DOES NOT LET MOST LENSES AUTOFOCUS. You'll notice that there is NO AF screw pin coming out of the black hole on the lower right.

Unless you have a lens with a built-in AF motor, there is no motor to turn the screwdriver AF connection of most of these AF lenses.

Look at the mount of your lens. If you see a big slotted screw head spin as you turn the manual focus ring, this adapter won't work; you need the LA-EA4. If you have a newer lens with internal electronic focussing that has no spinning screw head on the mount, this simpler adapter will let your lens autofocus just great.

Even if you have to focus manually, all data and exposure modes work just fine, coupling through this simpler adapter. If you're going to focus manually, this adapter works 100% with all lenses.

See the biggest screw at the bottom?

Minolta 50mm f/1.4

Rear, Minolta 50mm f/1.4.

That big screw on the bottom is the mechanical AF coupler. If your lens has this and it turns as you turn the focus ring, it will not autofocus with this LA-EA3 adapter. You need the LA-EA4 for AF with this lens.
