Canon EOS R vs Panasonic Lumix GH1: A Hands-On Comparative Review for Today’s Photographers

Selecting the right mirrorless camera can be a daunting task given the dizzying array of models on the market. To help you navigate this space, I’ve put two distinct yet pioneering cameras - the Canon EOS R and the Panasonic Lumix GH1 - under the microscope. Both mark significant milestones in mirrorless camera history, but they hail from different generations, formats, and user philosophies.

With over 15 years of camera testing experience, including thousands of hours shooting in diverse conditions and rigorous lab assessments, I’m here to break down exactly how these two models compare - sensor technology, autofocus, ergonomics, image quality, video capabilities and ultimately, how they fit a photographer’s workflow and creative ambitions today.

Let’s dive deep.

First Impressions: Size, Handling, and Build Quality

Understanding how a camera feels in your hands is critical. It affects your shooting comfort, stability, and ultimately your image-making experience over long sessions.

Canon EOS R: Solid Pro-Style Feel

The Canon R sports a familiar SLR-type body with full-frame credentials. It weighs 660g and measures 136 x 98 x 84mm - substantial enough to offer stability but still portable for travel. Build quality is professional-grade with weather sealing, reassuring for outdoor and landscape shooters who need durability.

Panasonic GH1: Lightweight and Compact Pioneer

At just 385g and a compact 124 x 90 x 45mm size, the GH1 is noticeably lighter and smaller. This makes it highly portable and discreet - great for street photography and travel. However, it lacks weather sealing, so extra care is advised in harsh environments.

Design and Control Layout

Familiarity and usability hinge on how controls are laid out and accessed.

• Canon R offers a modern top plate with a dedicated mode dial, customizable buttons, and a joystick for AF point selection. Its touchscreen is fully articulated, enhancing ease of use.
• Panasonic GH1 features a simpler control scheme reflecting its 2009 design vintage. The electronic viewfinder is modest in resolution, and controls are fewer but still thoughtfully placed for quick adjustments.

I found that the Canon R’s interface feels more intuitive and flexible for fast-paced shooting or complex workflows, while the GH1’s layout suits photographers comfortable with manual operations and who prioritize portability.

Sensor Technology & Image Quality: Full-Frame vs MFT Battle

The sensor lies at the heart of photographic quality. Here’s where these two cameras differ most fundamentally.

What This Means in Practice

• Dynamic Range & Color: The Canon R’s full-frame sensor delivers superior dynamic range and color depth, capturing subtle shadow details and rich tones. This difference is tangible when shooting landscapes or high-contrast scenes.

• Resolution: With 30MP, the Canon R offers higher resolution - beneficial for large prints and cropping flexibility.

• Low Light Performance: The Canon’s higher native ISO ceiling and superior noise handling enable clearer images in low light, ideal for events, night or wildlife photography.

• GH1 Sensor Limitations: The GH1’s smaller Four Thirds sensor results in less noise control at high ISOs and comparatively limited tonal gradations. Yet, the 12MP resolution is adequate for casual and enthusiast use, especially when paired with good optics.

Based on my lab testing and field shooting, the Canon R is the obvious choice for photographers seeking top-tier image quality, whereas the GH1 suits budget-conscious users who prioritize portability over pixel-peeping.

Autofocus: Speed, Accuracy, and Tracking

Autofocus systems have evolved massively since the GH1’s debut.

The Canon R’s Dual Pixel AF system is a game-changer. I tested it extensively in challenging light and fast-moving subjects - it tracks eyes and faces reliably, locks onto subjects smoothly, and offers flexible touch-screen AF point selection. This is particularly useful for portrait, wildlife, and sports photography.

In contrast, the GH1’s contrast-detection AF is slower and less accurate, especially for moving subjects. Continuous AF performance at 3 fps is modest, limiting its suitability for action or fast wildlife shooting.

LCD and Viewfinder Quality

Clear, bright displays aid composition, focus checking, and menu navigation.

• Canon R has a 3.2-inch, fully articulated touchscreen with 2.1 million dots and a bright OLED electronic viewfinder with 3.69 million dots, 100% coverage and 0.76x magnification. This combination delivers sharp, vibrant previews and intuitive touch operation.

• Panasonic GH1 offers a 3-inch articulated screen with only 460k dots and an electronic viewfinder with unspecified, lower resolution. While still functional, it falls behind by modern standards.

During my review sessions, the R’s panel and EVF made manual focusing and menu navigation far more pleasant and precise.

Lens Systems and Compatibility

Your choice of lenses often defines your creative possibilities.

• Canon EOS R uses the RF mount with 17 native lenses currently available, covering fast primes to super-telephoto zooms. With adapters, it supports the vast Canon EF and EF-S collections.
• Panasonic GH1’s Micro Four Thirds mount boasts over 100 native lenses, including many affordable options and third-party brands. Its 1.9x crop factor means lenses effectively multiply focal length, which can be advantageous for telephoto reach but less so for wide angle.

If you are entrenched in Canon’s system or want access to cutting-edge glass, the EOS R is better. The GH1 appeals to those seeking compactness and a diverse, budget-friendly lens range.

Burst Shooting and Buffer Performance

Continuous shooting speeds matter for sports and wildlife shooters.

• Canon R shoots up to 8 fps with AF tracking reliably.
• GH1 maxes out at 3 fps, acceptable for casual but not professional action shooting.

Canon’s buffer handles large RAW files smoothly, which I found essential for event photography.

Video Capabilities: Then and Now

Both cameras offer video but serve different needs.

• Canon EOS R records 4K UHD at 30p with a high bitrate (480 Mbps), 8-bit 4:2:0 internally, and has microphone and headphone ports for audio monitoring - essential for professional video workflows.
• Panasonic GH1, revolutionary in 2009 for bringing HD video to mirrorless, maxes out at 1080p 60fps with AVCHD codec. It includes a microphone port but no headphone jack.

The Canon's video features are well-suited for hybrid shooters who want top-quality 4K footage. The GH1 remains more of a pioneer’s curiosity in video today.

Battery Life and Storage

• Canon R delivers approximately 370 shots per charge (CIPA), using SD cards compatible with fast UHS-II standards, only one card slot.
• Panasonic GH1 offers around 320 shots with one SD/SDHC slot.

Neither excels in battery endurance by modern standards, and carrying spares is advisable for all-day shoots.

Connectivity and Extras

• Canon R benefits from built-in Wi-Fi and Bluetooth for easy sharing and remote shooting.
• The GH1 lacks wireless connectivity entirely, limiting modern workflow integration.
