docterMade it out today to test the newly acquired (used) Noblex 6/150 U. I was using ASA 100 film, rated at EI 50, so put the slow time module on the camera, and also exposed with the Panlux meter, which sets the shutter speed after you manually set (and program in) lens aperture.
Good news is that all of the equipment is working perfectly and I made a number of nice well-exposed negatives, with very even tones and no sign of banding. And using the shift was much easier in real time than I anticipated.
Bad news is that I made a bunch of careless mistakes from lack of familiarity with the equipment which resulted in several poorly exposed negatives. But those mistakes sent me back to the instruction manual(s) and next time out I hope to be better prepared. With the slow time module and exposure meter control this camera is fairly complex, certainly not as easy to use as a point and shoot film camera!
In terms of image quality my impression agrees with the comments made by others, i.e. it makes remarkable negatives with wall-to-wall sharpness and excellent contrast. The lens is a 50mm f/4.5 Docteur Optic.
