Having personally tested thousands of cameras over 15 years - from entry-level compacts to pro-grade bodies - I found the EOS M5 and GH5 II a compelling matchup between Canon’s advanced APS-C mirrorless and Panasonic’s pro Micro Four Thirds hybrid. This article draws on detailed lab testing, real-world shooting sessions, and workflow trials to give you an informed, balanced view - helping you pick the right tool for your photographic ambitions.

Let me walk you through key aspects ranging from sensor and autofocus tech to ergonomics, image quality, and usability across genres. I will also include unique insights from my experience capturing portraits in natural light, chasing wildlife, shooting sports, and producing video content.

At First Glance: Compact Sophistication Meets Pro-Grade Bulk

The Canon EOS M5 is a 2016 advanced mirrorless designed for serious enthusiasts migrating from DSLRs or looking for a lightweight alternative. Its APS-C sensor, DIGIC 7 engine, and Canon’s EF-M lens ecosystem provide a solid platform, especially for portraits and street photography.

In contrast, the Panasonic Lumix GH5 II, announced in mid-2021, builds on the revered GH5 legacy, targeting videographers and hybrid shooters needing robust weather-sealed bodies, versatile video specs, and a mature Micro Four Thirds lens ecosystem.

Let’s start by comparing their physical identities.

As you can see, the GH5 II is noticeably larger and heavier (727g vs 427g) with dimensions reflecting more extensive handling and controls. The Canon M5 balances portability with an SLR-style grip but remains very pocketable in most jackets.

This size delta affects not only how the cameras feel in hand but also influences battery size, lens options, and built-in features such as stabilization and flash presence.

Design & Controls: Where Form Meets Function

Checking the control layout and top design offers clues about who these cameras serve best in practice.

The GH5 II has a top LCD status panel missing on the M5, which relies heavily on the rear articulated touchscreen and viewfinder for info. The GH5 II's dual command dials, customizable buttons, and dedicated video-friendly controls make it a powerhouse for users who demand quick adjustments on the fly.

The M5’s more minimalist arrangement suits photographers who prioritize mobility and simplified operation while still offering sufficient customization.

The refined EVF resolution on the GH5 II (3680 dots) vs the M5’s 2360 dots also matters in critical focus situations, making framing and manual focusing easier during demanding shoots.

Sensor & Image Quality: Being a Size Matters Debate

When discussing image quality, sensor size and technology start the conversation. Both cameras use CMOS sensors but differ in format and resolution:

• Canon EOS M5: 24MP APS-C sensor (22.3 x 14.9mm), standard Bayer filter with anti-aliasing, DIGIC 7 processor
• Panasonic GH5 II: 20MP Four Thirds sensor (17.3 x 13mm), no anti-aliasing filter, advanced Venus Engine processing

At first glance, the M5’s APS-C sensor captures more detail at higher resolution (6000 x 4000 px), yielding slightly improved dynamic range (approx 12.4 EV) and superior low-light ISO performance (ISO 1262 per DxOMark) compared to the GH5 II’s 13.1 EV dynamic range and slightly lower high-ISO capability (ISO 1136).

However, the GH5 II benefits from the absence of an AA filter, which can provide crisper images in good light. In my landscape shoots, I observed the GH5 II delivering sharpness and color fidelity surprisingly close to the M5 when paired with high-quality glass. The compressed dynamic range is less of an obstacle when shooting RAW and leveraging excellent bracketing and post-processing workflows.

For portraits, the M5’s sensor produces more natural skin tones and better highlight roll-off, critical when rendering subtle complexion detail under natural window light.

Interface & Display: Touchscreens and Viewfinders in Action

Both cameras feature electronic viewfinders (EVFs) and rear LCDs but with different form factors:

The GH5 II’s 3-inch fully articulated touchscreen with 1840k dots rivals or surpasses many pro cameras, offering vivid preview and touch autofocus with a flip-out style perfect for vloggers or shooting at odd angles.

The M5 sports a slightly larger 3.2-inch tilting touchscreen with 1620k dots, bright and responsive, sufficient for standard shooting postures. It also leans into its selfie-friendly design, a plus for casual portraiture and street shooters.

In practice, I appreciate the GH5 II’s fully articulated screen for macro angles or video work, while the M5’s tilting display excels in portability without adding bulk.

Autofocus and Focusing Performance: Speed Meets Intelligence

Autofocus performance is crucial across almost all types of photography, especially wildlife and sports where speed and accuracy make the difference between a keeper and a missed shot.

The Canon M5 combines hybrid AF with 49 focus points that include phase and contrast detection, face detection, and eye autofocus - solid for its class but showing limitations with fast, erratically moving subjects. I found its eye detection AI effective with human faces but lacking animal eye detection, which shows when photographing pets or wildlife.

The Panasonic GH5 II steps up with 225 focus points and advanced contrast-detection AF (no phase detection sensor). Despite lacking phase detection, Panasonic’s Depth From Defocus technology combined with AI-based subject tracking, including animal and eye detect AF, performs impressively. The GH5 II’s AF feels quicker and more reliable for fast-moving wildlife and sports scenarios in my testing.

Continuous autofocus tracking at 12fps burst further favors the GH5 II over the M5’s 9fps, making Panasonic a better companion for action shooters.

Build Quality & Weather Sealing: Durability for the Field

Physical robustness becomes non-negotiable for professional and travel photographers who shoot outdoors:

• The GH5 II boasts weather sealing against dust and moisture, a magnesium alloy frame, and a design meant for challenging environments.
• The EOS M5, while well-built and fit for everyday use, lacks environmental sealing, so caution is advised in adverse weather.

The extra weight and bulk of the GH5 II correspond to this ruggedness - a worthwhile tradeoff if you frequently shoot in rain or dusty locales.

Lenses & System Compatibility: The Heart of Flexibility

A system’s lens ecosystem profoundly influences its longevity and versatility:

• The Canon M5 uses the EF-M mount with 23 native lenses available. While Canon’s EF and EF-S canon DSLR lenses can be used with an adapter, it adds size and weight.
• The Panasonic GH5 II accompanies the massive Micro Four Thirds lineup of over 108 lenses from Panasonic, Olympus, and third parties. This system includes excellent primes, zooms, macros, and specialized optics, particularly strong for video-centric lenses as well.

If your photography crosses multiple genres - from macro to wildlife to portrait - the GH5 II’s lens selection offers greater versatility and competitive pricing.

Battery Life & Storage: Longevity on the Go

Battery endurance matters on extended trips or events:

• Canon M5 delivers approximately 295 shots per charge. This is adequate for short outings but requires carrying spare batteries for longer sessions.
• Panasonic GH5 II pushes about 400 shots, benefiting from a larger battery and energy-efficient electronics.

The GH5 II also features dual SD card slots supporting UHS-II standards, crucial for buffer clearing during high burst rates or redundant backups - the M5 offers a single SD card slot with slower USB 2.0 transfer speeds.

Connectivity & Extras: Staying Connected and Ready

Both cameras provide wireless connectivity:

• The M5 supports built-in Wi-Fi, Bluetooth, and NFC for quick pairing and image sharing.
• The GH5 II offers Wi-Fi and Bluetooth but lacks NFC. It also includes USB 3.2 Gen 1 ports for faster tethering and transfers, a mic and headphone jack for serious audio monitoring, plus advanced video features supporting H.265 codec, 10-bit internal recording, and 4K at 60p.

The GH5 II’s pro video features clearly cater toward hybrid shooters and videographers, while the M5 concentrates on stills users with occasional video.
