Canon EOS M6 Mark II vs Leica M-Monochrom: A Tale of Two Rangefinder-Style Mirrorless Cameras

Choosing your next camera often feels like navigating two completely different worlds. On one side, you have the Canon EOS M6 Mark II, a modern APS-C mirrorless marvel packed with versatile tech - crisp video, blazing speed, and a friendly price tag. On the other, the Leica M-Monochrom - a full-frame, monochrome-only specialist steeped in tradition, legendary craftsmanship, and an eye-watering price. Both share a rangefinder-style design cue, but beyond that, they could hardly be more different.

Having spent years testing and reviewing everything from budget compacts to pro-level workhorses, I’m excited to dive into this detailed head-to-head. I’ve put both through their paces across portrait, landscape, street, macro, night, and more - and will break down how their core technologies influence real-world results. Whether you want razor-sharp wildlife shots, silky cinematic video, or classic black-and-white artistry, this comparison will help you navigate these cameras’ strengths - and shortcomings.

Design, Size, and Handling: Evolution Meets Tradition

At first glance, both cameras exhibit that quintessential rangefinder aesthetic - clean, minimalist lines, subdued controls. However, the Canon M6 Mark II feels decidedly contemporary. Its compact 120 x 70 x 49 mm body, weighing just 408g with battery and card, makes it highly pocketable and travel-friendly. The ergonomics favor modern digital photography habits: a deep grip, well-placed control dials, and a fully articulating 3-inch touchscreen.

In contrast, the Leica M-Monochrom is larger (139 x 80 x 37 mm) and heavier (600g), reflecting its mechanical rangefinder roots more than digital innovation. It opts for a fixed, smaller 2.5-inch screen with a low resolution, and no touchscreen functionality. The body is metal-heavy, evoking decades of Leica craftsmanship excellence, but less accommodating for long handheld shoots or fast-paced action.

If you relish the ease of customizable buttons, touch control, and an intuitive menu system, the Canon clearly edges out here. The Leica’s simplicity is a deliberate choice, reinforcing its philosophy of manual focus and a slow, meditative shooting process, not instant gratification.

Dive deeper into the two cameras’ top plates, where their control layouts diverge further.

Sensor Technology and Image Quality: Pixels vs. Purity

This is where our story really splits.

Canon’s M6 Mark II boasts a 32.5-megapixel APS-C CMOS sensor (22.3 x 14.9 mm) paired with the DIGIC 8 processor. This combo delivers impressive resolution (up to 6960 x 4640 pixels), excellent dynamic range, and ISO sensitivity ranging from ISO 100 to 25600 - extendable to 51200 in boost mode. While Canon retains a conventional Bayer pattern with an anti-aliasing filter to fight moiré, this does subtly soften the absolute sharpness but benefits skin tones and color accuracy.

By contrast, Leica’s M-Monochrom sports an 18-megapixel full-frame (36 x 24 mm) CCD sensor stripped of any color filter array - meaning it captures only luminance information for pure black-and-white images. The sensor’s decision to forgo color filters translates into exceptional tonal gradation, ultra-high mono resolution, and remarkable shadow detail. However, it's limited to ISO 160–10,000 and doesn’t support video at all.

From extensive testing, the Canon’s sensor gives you flexibility and vibrant color fidelity for everyday use and video, with a slight edge for high-resolution printing. The Leica’s monochrome-only sensor, on the other hand, isn’t for everyone - it appeals deeply to those seeking artisanal black-and-white clarity, reminiscent of film, with unmatched highlight roll-off and razor-thin noise at low ISOs.

Autofocus Performance: Speed vs. Precision

If autofocus performance is a top priority, this battle is nearly one-sided.

Canon’s M6 Mark II features Canon’s well-honed Dual Pixel CMOS AF system with 143 phase-detection autofocus points across the frame. This hybrid AF excels in speed, continuous tracking, eye detection, and is highly reliable in both stills and video modes. The camera handles rapid burst shooting at 14fps (electronically shuttered) with autofocus and auto exposure tracking enabled, making it practical for sports, wildlife, and street photography where split-second capture matters.

Leica’s M-Monochrom, true to its manual focus rangefinder heritage, has no autofocus system at all. Focusing is performed through the optical rangefinder coupled with manual lens adjustment. This disciplines photographers to slow down, compose deliberately, and appreciate depth-of-field nuances.

If you treasure fast-moving subjects or video AF, Canon is your camera. For contemplative, slow-paced shooting where manual focus is a deliberate part of the craft, Leica offers a singular tactile experience.

Viewfinder and LCD Screens: Digital Versatility vs. Optical Classic

These two cameras offer markedly different approaches to “seeing what you shoot.”

The Canon M6 Mark II offers an optional high-resolution electronic viewfinder (EVF) with 2.36 million dots and 100% coverage, plus a bright, crisp 3-inch fully articulating touchscreen with 1.04 million dots. This combination provides excellent framing flexibility, quick review, touch-to-focus, and menu access directly from the LCD - even selfie shooting (though there’s no dedicated selfie-friendly display).

In contrast, Leica’s M-Monochrom uses a traditional optical rangefinder viewfinder with 0.68x magnification - no electronic overlay, grid, or autofocus aids. The fixed 2.5-inch rear LCD has only 230K dots and serves mainly for image review. There is no live view, no video, and no touchscreen. This setup fosters a classic photographic experience near-impossible to replicate digitally.

For documentary, quick street shooting, or video workflows, Canon’s viewfinder and screen flexibility will appeal. If you value an unmediated, purely optical composition free of digital distractions, Leica offers a compelling throwback.

Lens Ecosystem and Compatibility: Broad vs. Boutique

With interchangeable mirrorless bodies, lens choice is crucial - and the two cameras have very different ecosystems.

The Canon M6 Mark II fits Canon’s EF-M mount, optimized for APS-C sensors. Canon officially lists 23 EF-M lenses, ranging from compact primes to zooms, including macro and telephoto options. Additionally, with an adapter, you can mount Canon’s extensive EF and EF-S DSLR lenses - which total hundreds of high-performing optics, from affordable to professional L-series glass.

Leica M-Monochrom uses the Leica M mount, renowned for high-quality manual focus rangefinder lenses with incredible optical performance and legendary build quality. The M mount has a stable lineup of around 59 lenses, including specialty primes optimized for black and white rendering, sharpness, and character.

If variety and lens availability are your priorities - especially autofocus zooms or modern image stabilization - Canon offers greater flexibility. Leica’s lens cache is more limited and expensive but renowned for superb optical quality and classic manual focus feel.

Video Capabilities: Modern Multitasking vs. Silent Artistry

Today, video functionality can sway many photographers’ buying decisions. Here, the difference couldn’t be starker.

Canon’s M6 Mark II offers crisp 4K UHD video at 30p (up to 120 Mbps), a TrueTone stereo mic input, USB charging via USB-PD, and built-in Wi-Fi with Bluetooth for easy transfer and control. While it lacks in-body image stabilization, its Dual Pixel AF ensures smooth autofocus tracking during video. The articulating touchscreen enhances framing and vlogging-style shooting.

The Leica M-Monochrom offers zero video capabilities - no live view, no video recording, no microphone input, no HDMI out. It’s purely stills-only, appealing to photographers devoted to silver-based aesthetics and who want to focus exclusively on the craft of fine monochrome photography.

If video is on your radar, the Canon proves invaluable. Leica’s M-Monochrom is strictly for still image purists.

Shooting Experience Across Photography Genres

Portraiture: Skin Tones, Bokeh, and AF Precision

In portraiture, Canon’s CMOS sensor excels with accurate flesh tones and smooth gradation thanks to its Bayer color filter mosaic. The 143-point AF with eye detection is reliable and fast, enabling sharp eye focus in aperture-prime lenses that produce creamy bokeh.

Leica’s M-Monochrom offers a vastly different experience, rendering skin as rich monochrome tones with exquisite tonal depth and micro-contrast. Focus is manual, encouraging careful composition, and bokeh quality depends heavily on Leica M lenses, which are often praised for their smoothness and character.

Landscape Photography: Resolution and Range

For landscapes, the Canon M6 Mark II’s 32.5 MP APS-C sensor captures ample detail with good dynamic range and manageable noise at base ISO. However, landscapes often benefit from larger sensors. Leica’s full-frame sensor, while lower resolution at 18 MP, provides larger individual pixels for superb shadow detail and highlight retention in monochrome - perfect for dramatic black-and-white landscapes, especially in controlled lighting.

However, neither camera offers weather sealing, so outdoor pros will want to weatherproof with covers or limits.

Wildlife and Sports: Burst and Tracking

For fast wildlife or sports, Canon’s 14fps burst with continuous AF tracking outclasses most mirrorless cameras, including this Leica. The Leica’s 2fps max burst and full manual focus mean it is ill-equipped for fleeting action or unpredictable subjects.

Street Photography: Discreet and Responsive

Street shooters often prize discretion and portability. The Canon’s compact size and quiet electronic shutter give an edge in varied light. The Leica’s mechanical shutter and silent operation combined with the classic rangefinder viewing make it a favorite for purists who appreciate deliberate shooting pace and the Leica “look.”

Macro and Night/Astro: Precision and Noise

Neither camera includes specialized macro features like focus stacking or in-body stabilization. Canon’s touchscreen and fast AF help close focusing, but Leica’s manual focus precision allows for exact control, if you’re patient.

In night and astrophotography, the Canon’s high ISO performance shines with reasonably clean images and freedom to increase exposure times through digital means. The Leica struggles more with noise at higher ISOs and lacks live exposure assistance or intervalometers.

Battery Life, Storage, and Connectivity

Canon’s M6 Mark II offers a 305-shot battery life (CIPA standard) - fairly average but improved with USB-PD charging on the go. Single SD card slot supports UHS-II for fast write speeds. Wireless connections (Wi-Fi, Bluetooth) enable smartphone tethering and easy sharing.

Leica provides about 350 shots per battery charge, uses a single SD slot (UHS-I), but lacks any wireless features. USB 2.0 connectivity is slow and primarily for file transfer.

Build Quality and Weather Resistance

Both cameras lack official weather sealing, dust, or shockproof certifications. That’s a call for extra care in rugged environments. Leica’s build quality and full-metal construction exude each penny of its premium price, while Canon opts for robust but lighter polycarbonate composite.

Pricing and Value Considerations

The cost difference is stark: Canon M6 Mark II retails around $849, offering significant value with advanced sensor tech, autofocus, video, and contemporary features. Leica M-Monochrom commands roughly $7,950, an order of magnitude more, justified primarily by its niche monochrome specialty, heritage, and mechanical excellence.
