Drop a .DNG file from your Leica Q3 Monochrom and get the exact mechanical shutter actuation count in seconds — processed entirely in your browser, never uploaded anywhere. The Q3 Monochrom stores its counter in Leica’s MakerNote inside the DNG.
Check Shutter Count →The Leica Q3 Monochrom is the monochrome-only variant of the 2023 Leica Q3, extending Leica’s long-running Monochrom line (M9 Monochrom, M-Monochrom Typ 246, M10 Monochrom, M11 Monochrom, Q2 Monochrom) into the Q-series. It pairs a 60 MP full-frame BSI CMOS sensor with NO Bayer colour filter array with the same fixed Leica Summilux 28mm f/1.7 ASPH lens that defines the Q3, driven by the Maestro IV image processor. Hybrid phase-detect + contrast-detect autofocus, 4K/60p and 8K/30p video, and the same tilt-touchscreen ergonomics as the colour Q3.
Leica does not publish an official shutter rating for the Q3 or Q3 Monochrom. Based on the Q2 Monochrom reference and Leica’s leaf-shutter design, the working estimate is approximately 200,000 mechanical actuations.

Every Leica Monochrom uses a sensor with the Bayer colour filter array physically removed. Instead of each pixel capturing red, green, or blue, every pixel captures full-spectrum luminance. That has three practical effects:
The trade-off: you cannot shoot colour. Every image comes out grayscale. The camera includes yellow/orange/red/green filter emulations for tonal contrast adjustment (mimicking traditional black-and-white film filters), but the sensor itself has no colour information to recover.
| Aspect | Q3 Monochrom | Q3 (colour) |
|---|---|---|
| Output | Black-and-white only | Colour + B&W conversion |
| Effective ISO | ~1 stop higher | Baseline |
| Sharpness | Per-pixel luminance (no demosaic) | Bayer demosaiced |
| Body / lens | Identical to Q3 | Identical to Q3 Monochrom |
| Video | 4K/8K monochrome only | 4K/8K colour |
| Shutter mechanism | Same leaf shutter | Same leaf shutter |
| Price | Premium over Q3 | Baseline |
Pick the Q3 Monochrom if you are a committed B&W photographer — the image-quality advantages are real and repeatable. Pick the Q3 if you shoot mixed colour/monochrome or want the flexibility of colour data in RAW even when you convert to B&W later. There is no reversible “colour mode” on the Monochrom.
Yes — a leaf shutter integrated into the fixed 28mm f/1.7 Summilux lens, identical to the Q3’s. Every mechanical shutter release increments the counter in the Leica MakerNote. Silent electronic shutter mode (up to 1/40,000 s) does not.
No. The sensor has no Bayer CFA — there is no colour information to recover. Every capture is grayscale, DNG and JPEG alike. The camera offers built-in colour-filter emulations (yellow, orange, red, green) that adjust tonal contrast the way traditional B&W film filters do, but the output remains monochrome.
Yes. The body dimensions, lens, hotshoe, USB-C port, and battery are identical to the Q3. Grips, half-cases, thumb rests, and lens hoods for the Q3 all fit the Q3 Monochrom.
The Leica MakerNote is generally preserved in JPEGs written directly by the Q3 Monochrom, but third-party edits usually strip it. Use the original DNG for reliability.
Only Leica Customer Care can reset the hardware counter, typically after a shutter replacement. Always verify the count from an original DNG file rather than screenshots from the seller.
