@akul: right angle of view and light for those buildings, but 28mm is a little makes me "depressed", if 15mm or larger may free something.
@nalahm: nice escaladders pic, for SD indoor shooting is a big task, I never took single one indoor.Btw, you could de-noise by use SPP 5.1.
@ thminhduc: is that the 120mm f/4 on Contax 645? How do you find changing the aperture?
This is it.To make lens from other than original works on camera, we need to fill gaps:
1-mechanical.
2-optical.
3-electronic.
4-digital communicative protocols.
This is more than a complicated work and not many people do that kind of work.As I answered this question many times, Pls refer to my previous posts.
