Camera is good, but the back has certainly seen better days. Everything works fine.
The center autofocus point hunts, but the other 4 autofocus points work fine and can be used to focus quickly with the lens (focus point is maintained after recomposition).
The lens is in like new condition. It is in great mechanical and optical shape.
I would like to get 400 Euros for the lens
The lens can be used on Sony E mount using a fringer adapter or with a daofeng adapter.
If you have a Sony A7 II or newer you could buy the fringer adapter and use this lens on both the N1 and the Sony with autofocus and all other features.
