Rare Lens
人肉接環試鏡片
An unnamed manufacturer, although the barrel bears the inscription 'B.A.F. L.F.D. 50' and with the s/n: 200027. Also included is '50', which I assume is a reference to the focal length of 50mm. Assuming that this is correct, then the lens has only one speed, namely wide open, at f2
