This is the discontinued SONY α series mount adapter LA-EA2 for A-mount lenses. It comes with a compact and convenient case. It's in very good condition, with only minor scratches on the mount joint. I have confirmed its operation with my A-mount lenses. Please be aware that it may not be compatible with all cameras. * STF lenses are manual focus only, and teleconverters cannot be used. * NEX-5/NEX-3/NEX-C3/NEX-VG10 require a firmware upgrade. This adapter allows you to attach A-mount lenses to E-mount camera bodies, enabling fast and accurate TTL phase-detection AF for both still images and videos! Please note that some lenses are not supported. Thank you for looking.
