This is an old 35 mm format manual focus lens with adapter to SONY E mount NEX series or new Alpha series MILC (mirrorless) body. Not a native SONY autofocus lens.

35 mm film camera lens' film coverage is 36 x 24 mm, so called full frame by digital standard.

E-mount. Not A-mount. For cameras like A7 A6000 NEX-5 etc.

YES it supports full frame on you A7.

I have fully tested this lens to ensure the functionality. The test photo is taken with this lens mounted on SONY NEX-5 digital.

If you use adapted lens on SONY digital for the first time, please do MENU → (Custom Settings) → [Release w/o Lens] → desired setting.

Please confirm you can use this lens.

If you are not sure about anything, please ask me.
