Sony A-mount

These lenses will fit on A-mount Cameras like the a99 or a77. To use them on E-mount cameras like the Sony a7 you need either the LA-EA4 adapter or the LA-EA3 adapter. Both adapters come with some limitations. The LA-EA4 offers fast AF with all Sony or Minolta A-mount lenses but the AF sensors are clustered around the center of the image and you loose some light to the adapter. The LA-EA3 will focus only with newer lenses and the focusing experience depends a lot on the exact camera model.
