marcbo Posted September 10, 2013 Share #1 Posted September 10, 2013 Advertisement (gone after registration) I now have the M(240) for 3 months . I tested it out thoroughly. It is a clear improvement on the M9 and will be perfect once the profile will be adjusted in LR. The results at high ISO are simply fantastic. I will not describe all of the improvements on the M9 but they are substantial and worth the investment in the M. What I'm less enthusiastic about is the results at low ISO (200) and high speed (1/2000), which gives vertical vignetting, not just in the corners but over the whole left and right side of the picture. The width of this vignetting strip is about 1/20 of the total width of the picture on the left and on the right. Is this is a case to be taken care of in a profile adjustment, to be solved in a future profile of LR or of the M(240) SW, is this normal or not?

pop Posted September 12, 2013 Share #5 Posted September 12, 2013 Thanks for your reply but I find it impossible to upload a meaningful pivcture, given the restrictions on the site. Are we to believe, then, that the vertical vignetting strip is visible only in the picture at its original full size? Link to post Share on other sites More sharing options...
250swb Posted September 12, 2013 Share #6 Posted September 12, 2013 It would add to the possible answers if you gave a clue to what lens you are using? I'm thinking you are maybe using a wide lens wide open, in which case the natural vignetting of the lens when wide open isn't always compensated for in the coding very well. It can be easily adjusted in post processing however. Steve Link to post Share on other sites More sharing options...

Fgcm Posted September 13, 2013 Share #8 Posted September 13, 2013 Never seen before. I cannot figure out how a vertical shutter could make a vertical vignette. Franco Link to post Share on other sites More sharing options...
thighslapper Posted September 13, 2013 Share #9 Posted September 13, 2013 Nor me. Probably a sensor/electronics issue. I would email Leica with a selection of typical images...... I think you will end up with a new camera..... Link to post Share on other sites More sharing options...
