The lens in original shape |
|
Back part was cut and put in helicoid thinnest adapter |
|
this is fixed distance. the lens was attached directly hand held, no adapter yet.
So to reach farther distance up to infinty, it's rear part must be cut. |
Now the lens is modified, ready to be used in NEX series.
Somehow it has slight fall off on corners, because the back lens is too close to sensor.
As a fast lens f1, it has good sharpness at wide open. It would be difficult to add aperture by the way.
So here it is.
