Since the Leica M (Typ 240) was introduced, there's been an ongoing debate regarding the merits of CCD vs. CMOS sensors. From a technological and marketing viewpoint, Leica needed to make the move from CCD to CMOS in order to offer live view and better low light performance. Live view has facilitated the easier use of ultra wide-angle lenses and opened up the possibility of using alternative glass like the wonderful Leica R lenses on an M body. And while no one can argue the additional functionality and superior high ISO capability afforded by CMOS on the M 240, there's been a steady and growing opinion that the color and tonality from the M9, which uses a CCD sensor, is more pleasing. I can appreciate that the resulting images from the two cameras do indeed look different, and everyone has personal tastes. I've shot thousands and thousands of images with the M9, as I have with the M 240 since then. Personally, I find both results appealing to my eye and never really made a direct comparison as they are different tools that I used at subsequent times through my photographic endeavors.

Recently, I read some comments online that I found somewhat puzzling. Statements were made to the effect that it was impossible to achieve the same color and tonality with the M 240, regardless of post processing. While I didn't know whether this was true or not, I've worked in digital imaging for 25 years and know that almost anything is possible in post. So, I decided to challenge myself and test the theory. I was heading out West for a family ski trip during my daughter's Winter break and would be spending a couple of days in San Francisco before flying back home to Miami. This would be a perfect opportunity to take the first step, so I packed up my M 240 and an M9, along with some of my favorite lenses: 24mm f/3.8 Elmar-M ASPH, 35mm f/1.4 Summilux-M ASPH FLE, 50mm f/2 APO-Summicron-M and 90mm f/2.8 Elmarit-M, then started thinking about how to go about testing. The goal would be to shoot roughly the same picture with each camera, using the same lens. So, if I took a shot with one camera with the 24mm mounted, I'd swap lenses and shoot the same lens with the same settings on the other camera. Truth be told, this was not the most fun way to shoot, but I was on a mission to get as many comparisons under various conditions as I could and stuck with the program.

When I returned home last week, I set about first just looking at the differences between the files once my import presets for each camera were applied. Then started the process of matching the files. I only used the global tools in Lightroom. No Photoshop. No adjustment brushes. Just slider adjustments. This proved to be most enlightening; I was able to pinpoint the changes necessary to achieve very similar results from the M 240 relatively quickly. To be clear, I didn't necessarily work the M 240 files to make them look the absolute best they could be. Rather, I took the challenge to match them to the finished M9 images to see if there was a definitive “CCD Look” that could or could not be replicated using a CMOS based camera. I also selected shooting scenarios that favored the M9, namely good directional, natural light, at lower ISO settings. This wasn't intended to be a competition between cameras, per se, but instead one to test the theory of inherent sensor color.

The next step is to now open this comparison up to the world at large and see if, despite my Lightroom processing, the “CCD Look” is still clearly identifiable when looking at these sets of images. So, I'm asking you, my intrepid readers, to take the challenge and see if you can correctly identify which images are from the M9. Don't vote for the one you think looks the best, just the one that you think is from the CCD sensor. Take a close look at each set of images. Click on them to enlarge (but do be aware that if you roll your mouse cursor over the images, we have a darkening rollover effect on our website – make sure your mouse is not over either image when viewing for comparison). Open two windows side-by-side. Do whatever you need to do. I've stripped away the metadata and changed the file names to protect the innocent, so no peeking. Once you vote on each set of images, you'll be able to see how others voted, but not image data. For that, I will publish a follow-up once we collect a statistically significant amount of votes, revealing the camera data and presenting my analysis. I know that there is a fairly large number of images (19 comparisons). Please do your best to select the M9 image from all the sets as this will help give us more accurate results.

Also, be sure to check out Part 2 of this article where I challenge you to select which camera took which image, without a direct comparison.

Now, let the voting begin!

    Will be interesting to see the results. I must say that some of the images that showed sensor spots were dead give a ways as from the M9?? I was never able to avoid this with my M9, have not had much of an issue with the M240.

    Excellent David
    What a great idea.
    What would be interesting in your analysis is to see whether anyone got them all right? Personally I found a criteria for guessing, which I’ve managed to apply consistently to all the images, the only guess I made is which was the M9 and which the M240!
    All the best

      Hi David, Great idea, great exercise!
      The image that formed in my mind was that “A” had slightly but consistently better performance in the shadows, and “B” in the liveliness of the colors. If that is correct I will have either very high or very low score. I assumed that “A” is the CMOS and “B” the CCD. I did only Part 1 so far. Can’t wait for the
      the results!!!!

      Either way, it was a treat to see your photos. Onto Part 2!

    Hey David,

    I did the voting I’m curious to the outcome, I did seem to vote against all others, every time I voted I was in the minority group. To me it never really mattered when I made the step from M9-P to M240, I think they are both nice but I like the M240 better just because the files are more flexible.

    David: loved the pictures. I am living in SC now but for ten years I lived in the Bay area, several years in Fontana West building, close to the places you photographed, and the pictures brought back happy memories. I left to go to Mexico in 1988, before digital was affordable, so I only have Ektachromes to remember the place, but they are still good after all these years. I now shoot my M6 Leitz glass on NEX-5/R, so can’t contribute to the poll, but I definitely see a difference between the pictures. One just grabs me while the other is a bit flat. I have shot thousands of pictures with Leitz/Leica glass and there is definitely a color difference between my lenses, and I wonder if the M9 users are using older glass than the 240 users, and could this be a reason for what they are seeing?

    Glad you took the time to take the pictures. Nice job all around.

    Is there anyone that can miss the original (corroded) Leica M9 IR glass? I would like to do some experiments with it. Thanks.
