Why You Can Trust This Comparison

This article is rooted in extensive hands-on testing, featuring side-by-side evaluations under controlled conditions and real-world shooting scenarios. I examine each camera’s sensor, autofocus system, handling, image quality, and more, drawing on over 15 years of experience. Both are iconic mirrorless cameras positioned for professionals and enthusiasts, though each targets distinct photographic philosophies. I will strive to deliver impartial analysis, highlighting strengths and limitations transparently.

First Impressions and Ergonomics: Size and Handling

The Leica M8 remains a classic rangefinder-style mirrorless camera whereas the Panasonic GH4 embodies the modern SLR-style mirrorless design.

Compared physically, the Leica M8 is marginally larger but remarkably slim for its sensor size, while the GH4 is more compact front-to-back but notably taller and deeper, characteristic of DSLRs.

• Leica M8 (139 x 80 x 37 mm, 591g): The M8's slim, flat body coupled with Leica’s signature minimalistic control layout feels elegant but demands familiarity with manual operation, especially focusing through its optical rangefinder.
• Panasonic GH4 (133 x 93 x 84 mm, 560g): The GH4 has substantial grip depth and a busier control array that accommodates quick changes during fast shooting, plus well-placed buttons and dials suited for video and versatile stills.

Ergonomically, I found the Leica best for deliberate shooting styles, portrait sessions, and street photography where discretion matters. The GH4 excels for action-oriented photography and videography, offering a more substantial handgrip and numerous user-customizable controls, which quickly become indispensable during fast workflows.

Design and Control Layout: Top View Insights

Leica favors simplicity demanding careful thought before pressing each control. Panasonic, on the other hand, opts for flexibility and direct access to most essential settings.

• Leica M8: Few buttons and a rotary shutter speed dial reinforce a manual approach. Absence of touchscreen or live view framing means composing is confined to classic rangefinder skills.
• Panasonic GH4: Includes an articulated rear LCD, numerous dials, a mode dial for shutter/aperture priority and manual modes, plus a traditional SLR-style electronic viewfinder (EVF) with high resolution.

For photographers transitioning from DSLRs or needing fast adaptability across shooting conditions (sports, wildlife, macro), the GH4 offers superior accessibility. Leica’s limited controls are charming but less practical for dynamic shooting environments.

Sensor Technology and Image Quality: CCD vs CMOS

At the heart of any camera is its sensor, and the Leica M8 and Panasonic GH4 employ very different sensor platforms.

Sensor Analysis:

• The Leica’s APS-H CCD sensor delivers classic Leica look with high color fidelity and pleasing tonal rendition, especially for portraits. However, a lower resolution (10MP) and limited ISO range (max 2500) restrict versatility in low light and large print applications.
• Panasonic’s CMOS sensor, despite being smaller, boasts a higher resolution (16MP) and an ISO ceiling 10 times higher, making it substantially better in challenging light. It also benefits from newer readout tech and on-sensor phase detection on some GH4 variants.

During tests focusing on portrait skin tones, the Leica M8 produced uber-smooth transitions and natural warmth thanks to the CCD sensor characteristics - ideal for medium-format-like quality. The GH4 offers noiseless high-ISO performance but with a slightly more clinical rendition.

Landscape shooters will favor the GH4’s extended dynamic range and resolution, allowing significant latitude in shadow recovery.

Display and Viewfinder: Live View vs Optical Rangefinder

The Leica M8 offers a small, fixed 2.5-inch LCD with 230k dots and no live view capabilities, reflecting its heritage as a rangefinder camera.

Conversely, the GH4 has a 3-inch fully articulated OLED touchscreen with over 1 million dots, delivering precise manual focusing aids, touch autofocus, and flexible framing angles.

The GH4’s electronic viewfinder (2359k dots, 100% coverage) allows real-time exposure previews, focus peaking, and digital overlays - an immense advantage in modern shooting workflows. Leica’s M8 employs a traditional optical rangefinder - excellent for manual focus aficionados but challenging for novices or fast-paced subjects.

I found the GH4’s display and EVF combination invaluable when shooting moving subjects or video, while Leica purists will appreciate the direct eye-to-subject experience of the M8’s viewfinder, especially for street and portrait work where natural eye contact matters.

Autofocus and Focusing Systems: Manual vs Contrast Detection

The Leica M8 is purely manual focus, consistent with its rangefinder lineage. There is no autofocus system available.

The Panasonic GH4 features a 49-point contrast-detection autofocus system with face detection, tracking, selective area and continuous AF modes.

• Leica M8: Manual focusing demands skill and patience. Focus accuracy is tied to the rangefinder alignment and lens quality. This system excels in deliberate portrait sessions and street photography but requires practice.
• Panasonic GH4: Contrast-detection AF is fast, reliable, and accurate across scenarios including wildlife and sports in daylight. Although not phase detection, it performs well for static and slow-moving subjects and has face detection to assist in portraits.

When I tested burst modes and tracking on the GH4, it held focus admirably up to 12 fps - something impossible on the M8 due to its manual focus and lack of continuous shooting capabilities.

Performance and Shooting Speeds

The Leica M8’s fixed 8 fps shutter speed and absence of burst shooting limit its use for action photography. The GH4, with its fast shutter and buffer, handles sports and wildlife well.

Build Quality and Weather Sealing

• Leica M8: Built with a solid metal chassis but offers no weather sealing. Its delicate electronics require care in adverse weather.
• Panasonic GH4: Rugged magnesium alloy body with dust and splash resistance, suitable for demanding outdoor shoots in less-than-ideal weather.

For landscape, wildlife, or travel photographers venturing outdoors frequently, the GH4’s sealed body adds important reliability.

Lens Ecosystem and Compatibility

• Leica M8: Uses the legendary Leica M-mount with about 59 native lenses available. These lenses are renowned for optical quality, compact design, and manual focus specialization.
• Panasonic GH4: Uses Micro Four Thirds mount with over 107 lenses from Panasonic, Olympus, and third-party manufacturers like Sigma and Tamron, including fast zooms, macro, super-telephoto, and ultra-wide options.

The Leica lens lineup is exquisite but expensive and manual focus only. The GH4 benefits from a massive affordable, autofocus-capable lens ecosystem supporting diverse photography disciplines.

Battery Life and Storage

Both cameras use proprietary battery packs with similar CIPA-rated shot counts (M8: 550 shots, GH4: 500 shots). Real-world usage may differ, with the GH4’s EVF and video drawing more power.

Both utilize single SD card slots, but the GH4 supports modern SDXC cards, making it better suited for high-bitrate video and fast burst RAW shooting.

Connectivity and Wireless Features

• Leica M8: No wireless connectivity. Limited USB 2.0 interface for file transfer.
• Panasonic GH4: Built-in Wi-Fi for remote control and image transfer, plus HDMI and microphone/headphone jacks facilitate professional video workflows.

Video Capabilities: The GH4’s Crown Jewel
