RRS Base Plate issue with M10 Monochrom


Recommended Posts

Advertisement (gone after registration)

Anybody else running into issues using the Really Right Stuff Base plate ( BM10 B ) specifically on the M10 Monochrom?

I'm attaching a photo (left: factory fit) showing the issue (only occurring on the side with the circular tab/retainer) where the base plate is pushing on the leatherette to the point where it's bubbling the material. I could certainly file the base plate down, but that's not ideal. According to RRS, they've heard vague rumors of concerns with the M10M. Also, I'm seeing that the rubber pad on the opposite side of the "problem spot" is slightly misaligned.

Exchanging is complicated by the fact that the item appears to be on backorder and RRS indicated they are not going to do another production run (i.e. it's a discontinued item). I may consider a universal L-bracket, but these base plates are pretty sweet. Incidentally, the L-bracket and grip from my M240 RRS variant appear to line up perfectly with the M10 model.

I've had great luck with RRS products in the past, but maybe I got a lemon. I imagine the tolerances are likely an issue on the Leica cutting/placement of the leatherette side of things, but that's going to get tricky to sort out.

Thanks for your feedback!

I emailed RRS specifically to ask which L bracket to use for the M10M.  Of course this is not the base plate issue you referenced but still similar in the general topic.  They said, due to demand, they don’t have a dedicated L Bracket for the M10M. I totally understand that limited demand doesn’t make sense for production costs.  However, they suggested using the more generic MC-L-multi camera L bracket.  I haven’t tried it yet due to the fit issues you are experiencing, albeit a different accessory.  Wondering if I can tag along on this thread to inquire as to anyone who has used this L Bracket on the M10M, and your thoughts to effectiveness

For what it's worth I have the same RRS plate, an M10 and M10M.  They both fit fine, no impact to the leatherette.  Might a slim o-ring or thin adder to the cushion pad adjust the tolerance just enough while preserving stability? 

I was hoping that adding an o-ring to the screw would work, but it did not improve the fit...moving the o-ring to the other side does indeed make the fit better. I may try to find some rubber or pad-material and epoxy it to that side.

See if the rubber pad can be pried up and centralised, it looks like the body wouldn't sit squarely but that's the other end to where your concern is. As John says above add a shim inside the baseplate or you could file the lip down.

I've hesitated to modify the plate (since I can still return/exchange it)...I'm going to wait a week or so to see if the product is indeed discontinued before I go down any permanent modification. I may try to exacto/cut the overhang before trying to recenter the pad.

      Many of us have already noticed it, but shooting @ iso 25000 is now a non-issue 😊

      I obtained a customer-release—not pre-release/beta—M10-R and compared it side-by-side with the M10 Monochrom (hereafter referred to as the M10-M) on a test scene at high ISO values.  The firmware version for both was the latest firmware currently available to the public: 10.20.27.20 for the M10-R (upgraded from the initial released 10.20.23.49 firmware that was pre-installed in the new camera), and 2.12.8.0 for the M10-M. 
      Methodology: all shots were taken on a tripod with a 2-second delay to minimize vibration.  The same Leica 50 APO lens was used for all tests.  The aperture was set to f/5.6 for all tests, at which the resolving power of the 50 APO is about as high as possible among commercially available 35-mm format lenses.  The ISO value and shutter speeds were as follows:
      ISO 6400, 1/60 s
      ISO 12500, 1/125 s
      ISO 25000, 1/250 s
      ISO 50000, 1/500 s
      ISO 100000 (M10-M only), 1/1000 s
      To the best of my ability, the M10-R and the M10-M were treated equally.  The test shots were taken in one sitting, with the same tripod position 2.2 m from the target, and under the same lighting.  The images were focused by rangefinder and confirmed by live view for each camera.  The subject distance (2.2 m) was farther from the test scene than my earlier M10-R tests (1.3 m) because I anticipated that the M10-M might have no trouble resolving all the details of the scene from 1.3 m, even at absurdly high ISOs.
      To keep the test as pure as possible, all the test shots were taken as DNG files, then transferred and opened in Adobe Photoshop 2020 with Camera Raw 12.3 (which has native M10-R support) with no corrections or adjustments to the default image settings, other than clicking “B&W” to convert the M10-R images to monochrome.  Therefore, this test does not really answer the question of how the performance between the cameras compares if one were to bring the full power of modern post-processing, noise removal, AI-driven scaling and sharpening, etc. to bear on the images.  It also does not exploit the important ability of adjusting the levels of different colors when converting color files to monochrome files—arguably the largest advantage of using the M10-R to generate monochrome photos instead of the M10-M.  Instead, the purpose of this test is to compare the acuity and noise level of the two cameras at ISO 6400 to ISO 50000.
      Overall, both cameras take remarkably good monochrome photos, even at ISO levels such as 12500 that would previously be considered out-of-reach.  Here are 100% crops from a small portion of the center region of both cameras (M10-R on the left, M10-M on the right).  Click on the image below to view it at 100% to avoid scaling artifacts.  I would have no hesitation using ISO 12500 monochrome images from either camera for virtually any application.  But of course there are substantial performance differences.

      Hello guest! Please register or sign in to view the hidden content. Hallo Gast! Du willst die Bilder sehen? Einfach registrieren oder anmelden! Finding #1: The M10-M captures higher acuity levels than the M10-R across the ISO range tested (6400 to 50000).
      As expected, given the lack of a Bayer color filter array (CFA) and no need to de-mosaic the red-, green-, or blue-filtered pixels, the M10-M offers significantly higher acuity than the M10-R.  To my eye, the advantage persists even if you give the M10-R an advantage of one or two stops: compare the sharpness of the fine features of the scene as captured by the M10-M at ISO 25000 vs. the M10-R at ISO 6400, or the M10-R at ISO 25000 to the M10-M at ISO 100000—a remarkable testament to the M10-M’s ability to capture a scene down to the smallest details, even zooming in to 100%.  Notice also that at the same ISO level, aperture, and shutter speed (chosen by each camera’s auto-shutter speed setting to be the same at all ISO levels!), the M10-M images are only modestly brighter than the M10-R; I was surprised that the Bayer CFA didn’t dim the M10-R images more strongly.  Perhaps the M10-R firmware partially compensates for the loss of light due to the Bayer CFA.
      Finding #2: The M10-M offers about a 1- to 2-stop advantage in high-ISO noise levels over the M10-R.
      Compare the M10-M at ISO 50000 to the M10-R at ISO 12500, or the M10-M at ISO 25000 to the M10-R at ISO 6400. The M10-M continues to blow me away with its high-ISO performance.  Indeed, Bill Claff’s measurements at https://photonstophotos.net/Charts/PDR.htm rank the M10-M’s high ISO performance as fourth among all cameras tested to date, behind the Phase One IQ4, the Phase One IQ3, and the Fuji GFX-100—three current or recent top-of-the-line medium format cameras.
      Overall, Leica has created in the M10-M and the M10-R two current-generation sister cameras with outstanding overall performance.  If acuity or high-ISO performance is more important than color for your particular application, than the M10-M outperforms the M10-R and is among the very best cameras to my knowledge, even joining some medium-format monsters.  And if color is needed, either in the final image or to enable creative conversion to black and white images that allows easy sky darkening, face lightening, etc. during post-processing, the M10-R remains an option worthy of its current flagship status among Leica M cameras.

      With the important caveat that this post is largely speculation, let's anticipate the performance characteristics of the M10-R sensor.
      The Leica S3 sensor is 45x30 mm (1350 sq mm) and the DNG files are 9816 x 6512, for a total pixel count of 63,921,792 pixels, or 47,349 pixels per sq mm
      The Leica M10 Monochrom sensor is 36 x 24 mm (864 sq mm) and the DNG files are 7864 x 5200 = 40,892,800 pixels, or 47,330 pixels per sq mm.
      The pixel density of the two sensors is so similar that I assume the discrepancy comes from non-scaling edge usage factors, and/or small 0.01 mm-scale rounding errors in sensor size.
      So if we assume that the S3 sensor and the M10 Monochrom sensor come from the same process, differing only in size and the presence of the Bayer color filter array in the former, then it's reasonable to assume the M10-R sensor also comes from the same process, and is basically a 36 x 24 mm crop of the S3 sensor (as others have hypothesized in this forum previously).  
      If this reasoning is correct, then you can expect the M10-R sensor to be the same as the M10M sensor, plus a Bayer CFA, and to perform more or less the same as the S3 sensor on a per-square-mm basis.  Therefore, I would expect:
      - DNG files that are 7864 x 5200 = 40,892,800 pixels
      - Dual gain design
      - 4.6 µm pixel pitch
      - Base ISO = 100
      - ISO range = 100-50,000 (basically one stop lower than the 160-100,000 ISO range of the M10 Monochrom, as one might predict from the lack of the Bayer CFA in the M10M)
      - 14 bits per pixel
      Good ISO 12,500 photos and decent ISO 25,000 photos would be terrific, and a significant improvement over the M10/M10-P, as noted here:
