I made a few modifications to the lens. First I took off the screw mount by loosening the three screws at the back and reassembled it in a position so that the scales for focus and aperture are in the upright position, when the lens is mounted to the camera. Then I opened the aperture all the way and put a mark on the adapter by scratching off the black color right at the position where the 1.7 number is. When you then turn the aperture ring, you can see to which number the aperture is closed. The third modification is inside the lens, when you set the focus to the nearest position then a silver colored tube is visible on the back which could make inner reflections inside the lens. To minimize this, I painted the tube with black matte color which is used in modelling and available in this tiny containers. The lens has a 35 mm filter thread and I bought also a lens hood for this. The hood has a front thread of 46 mm and on this I screwed a circular polarizing filter. With this modifcations the contrast of the lens is greatly improved by preserving all its character. The best results come out when the lens is stopped down a bit to approx. 4. But this is not a problem at all, because the character of the lens is not archived mainly by depth of field but by the really bad field curvature, which means that even stopped down it is never possible to get sharpness from edge to edge. That makes it a wonderful portrait lens and the bokeh swirls like crazy. When the flaring is too much it also helps to block the incoming light with a hand outside of the frame. Just experiment with it and have fun!

Woah! Your comment is very informative, thanks! I will also do what you have done on this wonderful lens! Btw, where did you buy the 35mm step up ring to attach on its thread? I would like to buy one.

Your criticisms should keep in mind, it's a CCTV lens, not a camera lens! Keep up the good work, interesting improvising.

I have the 25 & 50mm f1.4 version and love these on my M. the 50mm one even covers a full frame sensor, with minimal vignetting. Because of the flange distance and the mirrorbox of my 5D III, it functions as a macro lens. but on apsc mirrorless, it acts perfectly normal. super small, sharp and bright for small money. it's a no brainer
