On the other hand, Panasonic’s GH5 II is a control powerhouse, housing numerous customizable buttons, two control dials, and a joystick for swift autofocus point selection. Its menu system, while deep, remains logical after acclimation, complemented by a responsive touchscreen for quick setting adjustments.

If you prioritize quick access to a wide range of settings, especially for video, the GH5 II’s ergonomics edge out the Leica SL, which favors simplicity that some may find less flexible in fast-paced scenarios.

Sensors and Image Quality: The Heart of the Matter

Image quality starts at the sensor. Let’s dissect the sensor technologies and their measurable impact.

Leica SL

• Sensor: 24MP full-frame CMOS (36x24mm) without an anti-aliasing filter.
• Processor: Maestro II.
• ISO Range: 50-50000 (native).
• DXO Mark Scores: Overall 88, Color Depth 25.0 bits, Dynamic Range 13.4 EV, Low-Light ISO 1821.

The SL’s large sensor delivers excellent dynamic range and superb color depth, crucial for studio portraits or landscape work where tonal subtleties matter. The omission of an anti-aliasing filter sharpens detail at the risk of some moiré, but in practice, Leica balances this well with their processing pipeline.

Panasonic GH5 II

• Sensor: 20MP Four Thirds CMOS (17.3x13mm), also no AA filter.
• Processor: Custom-designed (undisclosed).
• ISO Range: 200-25600 native; extended down to 100.
• DXO Mark Scores: Overall 79, Color Depth 23.7 bits, Dynamic Range 13.1 EV, Low-Light ISO 1136.

The GH5 II’s smaller sensor inherently captures less light, impacting noise levels and high-ISO performance. Despite this, its dynamic range is respectable for the size and the sensor is well suited for sharp, detail-rich frames especially in good lighting.

Practical Takeaway: For still photographers focused on image quality - portrait, landscape, or commercial work - the Leica SL’s sensor is a clear winner for richness, tonal nuance, and flexibility in post-processing. The Panasonic GH5 II excels for users prioritizing portability and speed, especially in video, but that comes with some low-light compromises.

Viewing and Composing: Screens and Viewfinders

The ability to frame accurately and review images comfortably can dramatically affect workflow.

The Leica SL sports a fixed 3-inch, 1040k-dot touchscreen and a large, bright 4.4M-dot OLED electronic viewfinder with 0.8x magnification, excellent for detailed composition. While the screen isn’t articulated, the high resolution and tactile interface make reviewing images pleasant.

The GH5 II’s fully articulated 3-inch screen boasts a sharper 1.84M-dot resolution and touch support, invaluable for videographers and street photographers who need flexibility in framing angles. Its EVF, by contrast, offers a still solid 3.68M-dot resolution at 0.76x magnification.

Summary: Leica’s larger, higher-res EVF gives the SL an edge for precise framing in still photography, while the GH5 II’s articulated screen and competent EVF facilitate versatility, especially for multimedia creators.

Autofocus: Speed and Accuracy Across Genres

Autofocus performance defines how well you can capture decisive moments or track fast-moving subjects.

During my wildlife and sports tests, the GH5 II’s 225-point system with DFD technology outpaced the SL in tracking moving subjects and animal eye autofocus. This makes the GH5 II more reliable for action photography and wildlife where fast, continuous autofocus is essential.

The Leica SL autofocus, while reliable, exhibited more hunting in lower light and with erratic subject motion, limiting its suitability for sports or fast wildlife photography. However, for portraiture, it remains accurate and consistent.

Burst Shooting and Buffer Performance

High-speed burst capability is key for sports and wildlife shooters.

• Leica SL: 11 fps continuous shooting.
• Panasonic GH5 II: 12 fps continuous shooting.

Practically speaking, both cameras offer competitive frame rates, but the GH5 II’s larger buffer and faster memory card support (UHS-II in both slots) means you can sustain longer bursts without slowdown - a crucial factor when subjects demand rapid-fire capture.

Weather Sealing and Durability

Both cameras boast environmental sealing to resist dust and moisture but neither is fully waterproof.

The Leica SL’s build is impressively robust with a metal chassis engineered for professional field use. Panasonic follows suit with solid weather sealing, but the GH5 II’s predominantly plastic construction makes it feel less lock-tight.

If you shoot in adverse weather or rugged environments, the Leica SL edges slightly ahead in feel and confidence, though both will manage rain and dust with appropriate care.
