Herr Barnack Posted May 11, 2016 Share #1 Posted May 11, 2016 Advertisement (gone after registration) Most forum members are probably up to speed on CCD vs. CMOS sensors already. For those who may still have unanswered questions, here's an interesting and in depth comparison of CCD and CMOS sensors: http://petapixel.com/2016/05/10/infographic-difference-cmos-ccd-sensors/ I found it to be quite informative; I hope others will, too. 3 Quote Link to post Share on other sites More sharing options...

adan Posted May 21, 2016 Share #2 Posted May 21, 2016 A bit of corporate propaganda in some ways (note original source of the graphic). Carefully chooses characteristics that favor CMOS, while ignoring or downplaying those that still favor CCD. "Everyone is switching to CMOS" is the same as saying "vote for the candidate who is ahead in the polls." A self-fulfilling prophecy, that doesn't actually prove who's the better candidate. (NO real-world political reference intended). Power consumption difference may exist - but my CMOS Canon 5D/6Ds run through batteries at about the same rate as my CCD M9s. I carry backups for both. I have not noticed my CCD cameras running hotter than my CMOS cameras (my CMOS cameras definitely run hot shooting video). "Smear"? I haven't seen a still-camera CCD smear since the first PanaLeicas a dozen years ago (early M8 design problems excepted). Antiquated reference. I worked in a camera store until last fall, so I got to try them all. I have yet to see a CMOS that equals the color reproduction of my M9 CCDs - including the M240. However, some are getting closer (Sony Alpha 7's, Fuji X series). Their move to Backlit CMOS design seems to cut down on the excessive CMOS red cast and other CMOS issues (row and column noise, pattern noise, banding). It is certainly true that CMOS, for reasons having nothing to do with absolute quality (like cost, and video capability), will eventually win out. My hope is that by the time CCDs do disappear (as in, I can't buy even a used M9 ), CMOS will be as good as the M9 CCD for color and per-pixel resolution. 3 Quote Link to post Share on other sites More sharing options...
lct Posted May 21, 2016 Share #3 Posted May 21, 2016 Problem with CCD is noise and banding is far worst out of the M9 than M240 at high isos. I agree that the color rendition of my Sony A7s mod is more accurate than my M240's but not my Fuji X-E2's and the red cast of the M240 is hardly visible with Capture one since 2.0.0.11 firmware update in October 2013. Just an urban myth if you ask me but i agree that clipping reds are too easy to get with the M240. Would be my only serious gripe in all honesty but i'm not a pro photographer.

adan Posted May 21, 2016 Share #4 Posted May 21, 2016 Actually my experience was exactly the opposite. My M9 does not band at any ISO (very noisy, yes - but always a random pattern of speckles, no lines). It did get a case of jesus-lines a few years back, but that was a firmware-and-aging-batteries issue, not the CCD. Whereas when I tried 2-3 M240s, they all began showing faint bands at as low as ISO 1600, and always by ISO 2500. Attached is sample at M240 @ ISO 2500. Yellow room lighting, white-balanced manually. Random speckles, like film grain, are acceptable - I can live with "looks like Delta 3200" @ 3200. Clear patterns or streaks of digital origin are not, for me. Any more than I'd accept streaky lab processing of film, or streaks from a dirty film-M shutter curtain. So I can use the M9 CCD (unwillingly, sometimes) at ISO 2500, but can't trust the Leica CMOS, as currently implemented, above ISO 1600. Net loss of low-light capability. My mind will always be open to try upgrades, however. 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!

lct Posted May 21, 2016 Share #5 Posted May 21, 2016 Are you sure it's not an M9 image? Never got this at 2500 iso so far. Welcome, dear visitor!

lct Posted May 21, 2016 Share #6 Posted May 21, 2016 Here at 3200 iso. Still far from the A7s but the M9 is one generation behind. Welcome, dear visitor!

lct Posted May 21, 2016 Share #7 Posted May 21, 2016 (edited) Advertisement (gone after registration) Now at 6400 iso. Bit of banding perhaps but nothing disturbing really. Seems like you've based your opinion upon a lemon my friend. Welcome, dear visitor!
