The fact that many people on this forum would also have replied as you have, but less elegantly, really does call into question Lloyd's expertise, whether or not he has a dud sensor - which I'm sure can happen.

They all have vertical-travel blade shutters. I can only remember that the DCS100, based on the Nikon F3HP, had a horizontal travel shutter. Where their others? Just asking out of interest. If Leica had switched to a titanium foil shutter, they might have been able to use horizontal travel- no problem contaminating the sensor. I remember back in M8 days the discussion regarding the change in shutter mechanism. Edited January 7, 2021 by BrianS Link to post Share on other sites More sharing options...
adan Posted January 8, 2021 Share #43 Posted January 8, 2021 I'm sure in the digital M's the primary consideration is the size of the curtain spools. They take up a lot of volume that Leica needs for electronics in the digital bodies. See first image here: https://photo.imx.nl/technique/leica/page103.html The Nikon F3 electronic shutter (and likely the M7 shutter) save a little room by substituting chips and electromagnets for gears and springs. See last image: http://www.mir.com.my/rb/photography/hardwares/classics/nikonf3ver2/htmls/index2.htm But also keep in mind that the DCS100 did not need room for a lot of electronics besides the sensor - because it was permanently tethered to a motor-sized base-mounted processing unit, and an external storage module as big as a Domke bag. https://www.nikonweb.com/dcs100/ Anyone want a digital M 6"/15cm tall? In Fall 1992 the AP held a seminar on the DCS100 for all us local newspapers graphics types in San Juan, PR. They were so proud to tell us we could print up to 8" x 10" (A4) in color; or 11x14 with the monochrome version! (At newsprint resolution) And it would only cost us $25,000 (or we could rent one from the local AP office for special events). 1 Link to post Share on other sites More sharing options...

I waited for the DCS200 to come out. Have the first delivered IR version. It was "only" $12,400 for the body- an extra $4000 over the regular monochrome and color versions. The first Digital Sensor that I used required several flight racks of equipment, that was the early 1980s. Edited January 8, 2021 by BrianS Link to post Share on other sites More sharing options...

A huge boost in the Lightroom Dehaze control. Thank you for nailing this one . You always have to consider the context (what he is photographing ) and the Post Processing . He shoots his tests directly into the sun in extreme contrast situations . (I can t remember having a file I ETTR and then still had to lift the shadows 100% ). I would never intentionally set up a capture for such and extreme DR without using a graduated ND filter . THe 2nd issue is noted above use of post processing software to dramatically change the tone curve (Dehaze) without considering the artifacts . If you are familiar with any of the Topaz AI plug ins ..you know to look for these aberrations and pull back . I don t doubt for a minute that DL can create these issues on demand from his files . But I also know that I would be able to avoid them 100% of the time in my work . 2 1 Link to post Share on other sites More sharing options...
jaapv Posted January 16, 2021 Share #46 Posted January 16, 2021 Actually there is noting new here. Try overdoing the clarity slider on a greyscale image; it will create huge diffuse haloes like incompetent dodging. As I said before, DL is prone to crying wolf without understanding the issue. 1 Link to post Share on other sites More sharing options...

Try overdoing the clarity slider on a greyscale image; it will create huge diffuse haloes like incompetent dodging. As I said before, DL is prone to crying wolf without understanding the issue. DL is saying (via email) that the artifacts are visible before applying adjustments. I've tried applying massive amounts of all the discussed filters on complex, detailed images from the Q2M and cannot get the issue to show up, so the assumption some have made that this issue is a sometimes-unavoidable characteristic associated with monochrome sensors may not be accurate. Of course it could be the Q2 lens design, the extra 7mp, and/or the different design of the Q2 sensor that keeps it from showing up on the Q2M.

UliWer Posted January 30, 2021 Share #48 Posted January 30, 2021 Here is an example of a vertical line in the upper part of the frame's center from the M10 Monochrom: Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members! and enlarged: ISO 160, no filter on the lens (an old 2.8cm Hektor, lens detection disabled). I found the same on two other photos I took of the same scene in slightly different angles at the same time with just a few seconds between them. The RAWs taken by the camera were not altered - especially no dehazing. I checked many other files, but could not find the same vertical line. My theory is that it may occur if there is no structure at all in the upper center (in this case very bright blue sky). With only very slight clouds in the same region I cannot find anything similar even at max. enlargement.

UliWer Posted January 30, 2021 Share #50 Posted January 30, 2021 (edited) Yes, it's off center because I cropped not exactly in the center. My theory that it only occurs when there is no structure in the surroundings seems shattered. I found some other shots taken in April last year which show the same issue where the vertical line is surrounded by structures. Here one example, with an 21mm Super-Angulon, yellow filter, RAW-file unaltered, no dehazing, ISO 160. It is a strong crop from the frame's upper center, the line does not go though the whole frame, just one third: Welcome, dear visitor!

I just went outside to take something uniform in the center of the image. ISO 160 with APO 50mm, no filter. I cannot find any vertical, horizontal or anything else that appear anomalous (besides some sensor dust I need to clean). Link to post Share on other sites More sharing options...
BrianS Posted January 31, 2021 Share #52 Posted January 31, 2021 (edited) The sensor uses multiple A/D circuits to convert the acquired analog signal to digital. I'm thinking the calibration of the a/d circuitry is off somehow. Have you contacted Leica and furnished these sample images? I suspect this is a fix applied via firmware.

UliWer Posted February 21, 2021 Share #54 Posted February 21, 2021 My camera which showed the vertical lines illustratred above in #48 and #50 went to Wetzlar and came back yesterday. The first diagnosis - without having the camera at hand - was that it was a sensor issue. Though it wasn‘t as they changed the board set, not the sensor. I havn‘t had much opportunity to look if it is cured though what I have seen yet looks good. 2 Link to post Share on other sites More sharing options...

jplomley Posted April 24, 2021 Share #56 Posted April 24, 2021 If I use the Auto transform function in LR (or perform manually), I observe a waffle pattern in the shadows that I am certain would show up in prints. Happens on both M10M's (July 2020 and January 2021 dates of manufacture). I've a feeling this is a LR issue. Link to post Share on other sites More sharing options...
