Performance of Canon demi 17

Transplanted Canon SH 30 mm/f1.7 lens was tested today and took effect as I imagined on SONY Nex 5 APS image sensor. I have no complain it's performance and further session would withdraw more potential than ever circumstance that it was originally fit in "demi EE 17" while silver salt period. Sharpness, resolution and perspective are available even now. Smaller, lighter and handy means that there would be much opportunity to be bring out for every session at all. I have no inferiority complex to use this one among photographers armed with the latest machinery, yes, I will win, over ride on them and defeat them.
