Canon EOS R5 vs Leica SL2: The In-Depth Battle of Pro Mirrorless Titans

Choosing between two top-tier full-frame mirrorless cameras can feel like navigating a maze. The Canon EOS R5 and the Leica SL2 are both stellar, professional-grade tools, each with their devoted fanbase - and for good reason. Having spent years testing cameras across every genre of photography, I’m here to cut through the specs and marketing noise. Let’s unpack what these beasts really offer on the field, in the studio, and during those midnight shoots.

Whether you’re a portrait specialist, a landscape enthusiast, a wildlife chaser, or a video creator, understanding the meaningful distinctions will ensure you spend your hard-earned dollars wisely. Grab a coffee, and let’s get into the details.

Getting a Feel: Size, Handling, and Ergonomics

Let’s kick off by talking about something often overlooked in spec sheets: the way a camera feels in your hands after a full day of shooting. Ergonomics can make or break your experience.

The Canon R5 weighs in at a reasonable 738g and measures 138x98x88mm, sporting a classic SLR-style mirrorless body shape. It strikes a well-balanced middle ground - comfortable for handheld shooting, yet not so hefty it tires your wrist. Its grip is deep enough to accommodate larger hands without needing those aftermarket thumb clubs.

On the other hand, the Leica SL2 tips the scales at 835g, slightly heavier and with more substantial dimensions: 146x107x83mm. That heft translates to a robust, rock-solid feel that conveys durability - exactly what Leica aims for in their pro-market segment. However, it’s certainly chunkier in your hand, potentially less ideal for long street shoots or travel where size and weight matter.

Control-wise, the R5 embraces intuitive Canon ergonomics which many photographers have come to love - customizable wheels and dials, easy thumb access, and a touchscreen that’s both responsive and well-placed. The Leica SL2 assumes you understand manual controls and offers a slightly sparser but very solid interface with large, crisp buttons. It foregoes illuminated buttons, which some might find limiting under low light.

My Take

If you prize comfort over extended sessions, the Canon R5’s size and grip will likely suit you better. For those who want a no-nonsense, pro-grade tool that feels like a precision instrument, the SL2’s build quality shines, but it’s a bit of a handful for casual or travel photography.

Peering Into the Sensor: Resolution, Technology, and Image Quality

Now for the heart of any camera - the sensor. Both are sturdy 36x24mm full-frame CMOS sensors, but their architecture and resolution set them apart.

• Canon EOS R5: 45 megapixels, includes an anti-aliasing filter, native ISO up to 51,200 (expandable to 102,400)
• Leica SL2: 47 megapixels, no anti-aliasing filter (for crisper detail), native ISO up to 50,000

Sensor Insights

The slight edge in resolution belongs to the Leica SL2, but in practical terms, that 2-megapixel difference won’t be a game-changer for most. The Leica’s lack of an anti-aliasing filter means images capture razor-sharp detail, especially beneficial for landscape and studio work requiring ultimate resolution.

The Canon R5’s sensor is modern and boasts an excellent dynamic range. Canon’s inclusion of a sensor-integrated 5-axis image stabilization system (IBIS) is a huge bonus for both stills and video, significantly reducing shake, especially in macro or low-light scenarios. The Leica SL2 also offers sensor-based stabilization, though its system performs differently owing to its sensor design and processing pipeline.

Real-World Image Quality

In testing, both cameras produce pleasing color tones and excellent detail. The R5 tends to generate slightly warmer images with skin tones that feel more pleasing straight out of camera, useful for portraiture. Leica’s images have more clinical precision, favoring those who love to tweak raw files or want ultra-fine detail for large prints.

You won’t find a significant difference in low-light performance here, though Canon’s broader boosted ISO range offers more headroom in extreme darkness.

The Autofocus Face-Off: Speed, Accuracy, and Tracking

Arguably the most critical feature for professionals is autofocus (AF). Whether chasing wildlife, sports, or candids, the camera must nail focus consistently.

Canon’s Dual Pixel CMOS AF II system is a beast, proven across Canon’s lineup with blazing speed and near-perfect accuracy. It includes eye and animal eye detection, crucial for portrait photographers and wildlife shooters alike. This makes the R5 a winner for fast-moving subjects and situations where precision counts.

Leica’s AF, relying mainly on contrast detection, while precise in controlled settings, lags behind with dynamic scenes. Although it offers face detection, it does not extend to animal eyes, a setback for wildlife professionals.

From my hands-on testing, the R5’s AF is much less prone to hunting and lock loses in tricky light and complex backgrounds.

Viewing and Composing Images: Screen and Viewfinder Quality

Both cameras sport sizeable 3.2-inch LCD screens offering 2.1 million dots resolution, but their articulation and usability differ.

• Canon R5: Fully articulating touchscreen, selfie-friendly (a bonus for vloggers)
• Leica SL2: Fixed touchscreen, less flexible

An articulating screen like Canon’s greatly aids videographers, macro shooters, and anyone who shoots off-axis. Leica’s fixed screen, while crystal clear, limits shooting angles and creativity somewhat.

Both have excellent electronic viewfinders (EVFs) with 5.76 million dot resolution offering 100% coverage, so no real loss on the classic eye-level experience. Leica edges slightly with 0.78x magnification versus Canon’s 0.76x, giving a marginally larger viewfinder window.

Burst Rates and Buffer: Action and Sports Shooting

If you shoot sports or wildlife, continuous shooting speed and buffer depth can make or break your shot list.

*Leica’s buffer depth isn’t officially published but tested results show a smaller burst buffer compared to Canon.

The SL2 boasts a blazing 20 FPS mechanical shutter speed, impressive for an all-around mirrorless camera, matching top-tier sports cams. However, Canon’s electronic shutter also delivers approximately 20 FPS with less noise and less wear.

Buffer wise, the R5 excels thanks to dual CFexpress + SD card slots optimizing write speeds, letting you shoot longer bursts without lagging. Leica’s dual SD cards only (no CFexpress) slow down write speeds a bit.

Video Capabilities: What Creators Need to Know

Video shooters will find themselves Calibrated a little differently between these two.

• The Canon R5 supports up to 8K 30p RAW recording internally, 4K at 120 fps, plus HDR PQ profiles and Canon Log for grade-worthy footage. Its built-in 5-axis stabilization combined with compatible lens stabilizers results in smooth handheld video.
• The Leica SL2 maxes at 4K DCI (4096x2160) at 60p with 10-bit 4:2:2 internally; though stellar, it has no 8K option. Its video codec support is mostly H.264 in MOV containers, common but less versatile for pro workflows.

Both have microphone and headphone jacks, HDMI out, and clean output switching, but the Canon edges out with superior video versatility and frame rate options.

For vloggers or hybrid shooters who prioritize video quality, Canon R5 is the obvious winner, but Leica’s video is still strong for cinematic creators not chasing ultra-high resolution.

Durability and Weather Resistance: Ready for the Field?

Both cameras provide comprehensive sealing against dust and moisture.

• Canon R5: Magnesium alloy body with extensive weather sealing rated for professional use.
• Leica SL2: Also magnesium alloy with industrial-grade weather sealing; Leica markets this camera as a rugged beast for challenging conditions.

Neither camera is fully waterproof, shockproof, or crushproof, so you still want to exercise care, but both will survive rain and dust plenty well.

Lens Ecosystem and Compatibility: Investing Beyond the Body

Buying a camera is buying into a whole ecosystem; lenses often dictate your long-term satisfaction.

• Canon R5: Uses the RF mount with 17 native lenses available - from affordable f/2.8 zooms to exotic L-series primes. Canon’s RF glass has quickly expanded with excellent image quality and optical stabilization. Plus, adaptors allow flawless use of Canon EF lenses, opening a gigantic back catalog.
• Leica SL2: Employs Leica’s L mount, shared with Panasonic and Sigma in the L-mount alliance, giving access to over 30 native lenses. While the collection is superb, Leica glass is often very pricey, reflecting the brand’s boutique status.

If budget or lens options concern you, Canon’s RF ecosystem offers more bang for your buck, especially with third-party support set to broaden.

Battery Life and Storage Options

• Canon R5: Rated for ~320 shots per charge using the LP-E6NH battery, with two card slots (CFexpress + SD UHS-II). Dual slots support overflow or backup - useful for pros shooting weddings or events.
• Leica SL2: Slightly longer battery life at ~370 shots, but the battery is built-in, meaning no quick swaps in the field. Dual SD slots (UHS-II on slot 1), but no CFexpress support - still fast but not as future-proof for high bitrate video.

If you’re battery-conscious and shoot long days, the Canon’s removable battery and dual card types give you more flexibility.

Which Camera Excels at Which Photography Genre?

Let's dive into real-world applications, supported by scores that represent field-tested performance.

• Portrait Photography: Canon R5’s eye and animal eye AF + pleasing color tones take the win. Leica’s resolution and sharpness do appeal to high-end portrait and fashion shooters who like post-processing flexibility.
