Canon EOS R5 vs Leica M11: An Expert’s Take on Two Pro Mirrorless Titans

Over my 15-plus years of field testing and reviewing professional cameras, I’ve encountered countless models that carve unique niches in the photography world. Today, I’m taking a deep dive into two very different yet equally compelling pro mirrorless cameras: the Canon EOS R5 and the Leica M11.

These cameras embody contrasting philosophies - one, a technologically packed hybrid powerhouse aimed at versatility and speed; the other, a minimalist, rangefinder-style marvel boasting unparalleled image fidelity and craftsmanship. If you’re midway through your research and wondering which might be your perfect fit, I invite you to come along as I unpack their nuances, share real-world insights, and break down how they perform across diverse photography styles.

First Impressions and Ergonomics: Size Matters, But So Does Feel

Right out of the gate, how a camera feels in the hand often shapes long-term shooting joy. Both the R5 and M11 are “professional mirrorless” but echo radically different design legacies.

The Canon R5 is solid and well-balanced with SLR-style ergonomics. Its robust grip and thoughtfully placed buttons give you instant access to critical controls - something I especially appreciate during fast-paced shoots. The R5’s magnesium alloy body is weather-sealed, instilling confidence in challenging outdoor conditions.

In contrast, the Leica M11 embraces a pure rangefinder form factor - noticeably slimmer and lighter. At 640g versus the R5’s 738g and with a footprint of 139x80x39mm against 138x98x88mm, the M11’s sleekness lends itself to discreet, portable shooting. It feels less “camera” and more like a precision instrument, which will appeal strongly to street photographers or those craving stealth.

Where the R5 delivers tactile dials, illuminated buttons, and a configurable interface built for speed and customization, the M11 leans into minimalism. Controls are pared down, reliant on manual focusing and an optical viewfinder (rangefinder coupling only), offering a true analog-meets-digital experience.

Design Philosophy and Layout: Technology Meets Tradition

Studying the top, I experienced firsthand how Canon’s R5 privileges quick adaptability. The dual control dials, dedicated ISO and exposure compensation buttons, top LCD panel, and AF modes are within thumb and finger reach - ideal when capturing moments that demand split-second decisions.

By contrast, the Leica M11’s layout is stripped down, lacking that top status screen and many direct-access buttons, reinforcing its “slow and deliberate” shooting style. It’s built for photographers who want to engage actively with composing, focusing, and exposure without digital distractions.

Sensor Technology and Image Quality: Resolution, Detail, and Dynamic Range

Both cameras boast full-frame sensors sized 36x24mm, but their approaches to sensor design and output are quite distinct.

• Canon R5 features a 45.0MP CMOS sensor with a standard Bayer filter and an antialiasing filter, processed by the powerful Digic X engine. Its 8192x5464 max resolution balances tremendous detail with manageable file sizes. The sensor includes a native ISO range of 100-51200, expandable to 50-102400, facilitating clean images even in tricky lighting.

• The Leica M11 pushes pixel count further to 60MP from its BSI-CMOS sensor (also with antialiasing), maxing out at 9528 x 6328 resolution. Leica’s sensor excels in color depth and dynamic range, thanks to enhanced signal-to-noise ratios and sensor design focused on detail retention.

Across my tests, the Leica’s images are breathtaking under controlled lighting, with nuanced tones and sharp micro-contrast. The M11’s RAW files provide excellent latitude for post-processing, especially for fine art and studio work.

The R5, however, offers greater versatility in sensor performance - particularly at higher ISO - and consistently delivers excellent sharpness with Canon’s superb in-camera noise processing and the plethora of RF lenses at its disposal.

Viewing and Interface: Electronic Versus Optical Experience

The Canon R5 sports a 3.2" fully articulating LCD touchscreen (2100k dots) plus a high-res (5760k dots), 0.76x magnification, 100% coverage electronic viewfinder (EVF). The EVF provides instant exposure previews and overlays (histograms, focus peaking) that I found invaluable when shooting in difficult light or wildlife.

Conversely, the Leica M11 embraces tradition with a rangefinder optical viewfinder, magnification 0.73x, and no electronic overlay. The rear touchscreen (3.0”, 2333k dots) supports live view but lacks touch AF controls - reflective of Leica’s manual-focus ethos.

For portraiture or fast-moving subjects, the R5’s EVF with face and eye detection AF is a clear advantage. The M11 rewards those who relish the tactile, immersive experience of manual focus, focusing screens, and optical framing.

Autofocus and Shooting Speed: Catching the Moment Versus Savoring It

Here is where the cameras' intent truly diverges.

• Canon R5 autofocus system is world-class: 1053 AF points utilizing Dual Pixel CMOS AF II with face and eye detection combined with continuous AF tracking. This hybrid system performs superbly in daylight, low light, or action sequences.

• Burst shooting tops out at 12 fps (mechanical shutter), critical for sports and wildlife photographers capturing decisive moments.

• Leica M11 dispenses with autofocus altogether; it’s a fully manual focus camera. Continuous shooting is a modest 4.5 fps, enough for composed sequences but not rapid-fire action.

If you’re trying to photograph hummingbirds or play-by-play stadium action, the Canon shines. The Leica demands precision, planning, and patience - perfect for introspective street work or deliberate portraiture.

Build Quality and Weather Resistance: Trust in Any Environment

Both cameras feature weather sealing - a must-have in demanding professional environments.

The Canon R5’s body is a rugged magnesium alloy shell with extensive sealing against dust and moisture, designed to hold up under rough use. My outdoor shoots across rain, dust, and cold environments confirmed it’s ready for adventure.

The Leica M11 also offers comprehensive weather sealing, a testament to decades of Leica craftsmanship and resilience. Its rangefinder body is surprisingly robust and capable in moderate conditions, though the user must be mindful of the lenses, which vary widely in build.

Neither camera is shock, crush, or freeze proof, so protective gear remains advised in extreme conditions.

Lens Ecosystem: Canon RF Versus Leica M Lenses - A Tale of Two Systems

Lens choice makes or breaks camera usability. The Canon EOS R5 leverages Canon’s ambitious RF mount, already home to 17 native lenses, with rapid expansions of high-performance primes and zooms.

• RF lenses benefit from cutting-edge optics, rapid autofocus, and fully integrated image stabilization in some models.
• From wide-angle landscapes to ultra-telephoto wildlife lenses, the RF system has tremendous diversity.

The Leica M11 uses the venerable Leica M mount, famous for its optical quality and artisanal prime lenses - 62 options, mostly manual focus.

• Leica M lenses are celebrated for their character and rendering style, prized by portraitists and street photographers.
• However, autofocus and electronic communication are absent, limiting versatility in some demanding genres.

Canon’s RF lineup offers a technical advantage for speed and reach, while Leica’s M lenses reward connoisseurs who favor ultimate image quality and manual artistry.

Battery Life and Storage: Endurance and Convenience

• The Canon R5 uses the LP-E6NH battery, rated for approximately 320 shots per charge (CIPA). While not stellar for a professional camera, I found it adequate with spares and efficient power management. Dual card slots supporting CFexpress and SD (UHS-II) enhance reliability and speed.

• The Leica M11 stands out with an excellent battery life of 700 shots per charge, almost double the R5. The single UHS II SD card slot is straightforward but demands more vigilance with backups.

For extended travel or remote assignments, Leica’s endurance is a strong plus, provided you can carry extra cards.
