All the picture taken from short distance to infinity (not real for the moment) at full width open aperture.

The Back lens has bee removed and just place by hand in front of a M42 Confirm focus adapter 50mm F/1.7. This is light actually entering a little bit on the side of the lens in the back. The lens is not perfectly in line with the camera too (difficult to keep the lens in the good place once you take picture with the camera). Soo ... think that those picture are the worst you can have before to fully modified the lens.


All picture taken with the sony A900, with Aperture Priority mode. PP in lightroom by adding some sharpen, clarity, contrast, ... . After that compressed to 75p jpeg sRGB.
