Infographic: The Difference Between CMOS and CCD Sensors

Recommended Posts

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:



I found it to be quite informative; I hope others will, too.

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.

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 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.

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.

Here at 3200 iso. Still far from the A7s but the M9 is one generation behind.

Now at 6400 iso. Bit of banding perhaps but nothing disturbing really. Seems like you've based your opinion upon a lemon my friend.

      Now that Leica has acquired Sinar, it might help many of us to have a forum on the Sinar Digital camera/LF digital backs/& lenses.
      I am specifically trying to gather ideas and tips of how to use my old Sinar f and go digital with it.
      Anyone with such interests, information and experience here? Would be happy to learn whatever I can on this. Thank you.

      ich selber habe die Kamera erst vor ca. 1 Monat beim Fachhändler erworben.
      Ich konnte einfach nicht wiederstehen und wollte meine Schwarze gegen eine in Silber tauschen. Nun muss ich eingestehen die Schwarze hat auch was.
      Da ich mich irgendwie nicht zwischen den beiden entscheiden kann, biete ich hier beide an. Eine werde ich aber natürlich behalten, je nach dem.
      Die Kamera befindet sich meiner Meinung nach in einem sehr gutem Zustand. Es gibt ganz vereinzelnde Flecken in der Verchromung, welche aber nur bei bestimmtem Lichteinfall zu sehen sind. Viele würden sagen wie neu.
      Auslösungen: 2852 (Bild 9, es können aber noch welche dazu kommen).

      Die Kamera hat 2019 den neuen Sensor ohne Korrosion bekommen (Bild 8).

      Funktion natürlich einwandfrei, Nichtraucherhaushalt. Lieferumfang müsste komplett sein, bis auf den Schwarz-Weiss Ausdruck.
      Kaufbelege, den Beleg vom Sensor tausch und OVP natürlich dabei.
      Versand inklusive oder Abholung in 74523 Schwäbisch Hall.

      Gruss Michael

      P.S. Da von privat weder Rückgabe noch Garantie meinerseits.

      Some years of happy using first version Monochrom had lead me to try out the M246.
      Hesitation for long because in my view, I didn't want to replace my MM1 with the later Monochrom.
      So opportunity came with a "nice like new M246" presented itself, some weeks ago.
      Over time some reasons like CCD/CMOS debats delayed untill I've found myself that the CCD/CMOS war was not a problem for me,
      in my practices and final results in pictures.
      With once replaced CCD sensor on my MM1 (no charge), I always fear another need to "replace again" this time with expensive notes.
      Have read that sometimes, three or four replacements of same MM1 said sensor.
      The good news is, the output of M246 is equal to (if not better than ! ) MM1 one's 😊.
      In use this M246 is much responsive and I appreciate more modern features.
      At first , I thought that the LED illuminated frame lines would bother me, but in use it's a very nice improvement.
      The frames lines show up within 1 second when switch "ON", so nothing to complain.
      No "flare" when used in contre-jour situation, as sometimes happen with MM1 (very rare but there as other film M even MP ).
      In very dim scenes, this is a must, and I can use also LCD/EVF if need be = incredible this enhanced light features (a bit flickering, I admit but usable).
      When I want to use some colored filters,  preview of filter rendering with rear LCD or EVF is something I've never think of.
      I'll give myself more time to "compare" them more than a couple of weeks.
      Please feel free to give your opinions on the outputs of Monochrom CCD/CMOS if you had used (or use now) the two nice Monochroms from Leica.
