Inside the Machine: Sensor Tech and Image Quality

Sensor architecture defines a camera’s potential image quality. The Leica M9 houses an 18 MP full-frame CCD sensor measuring 36x24 mm (864 mm² sensor area). In contrast, the GH5 II features a 20 MP Micro Four Thirds CMOS sensor at 17.3x13 mm (225 mm² sensor area).

This size difference of nearly fourfold dramatically influences both light gathering and noise behavior.

Resolution and Detail

In raw resolution numbers, the GH5 II slightly edges out the M9 with 5184x3888 pixels vs. 5212x3472 pixels, but pixel density is much higher on the smaller sensor.

Practically, the Leica’s larger pixels yield higher dynamic range and superior tonal gradation, particularly notable in landscape and portrait captures where preserving highlight and shadow details is critical. The CCD sensor, while older technology, produces a distinct color ethos - often called “film-like” - with smooth tonality, pleasing skin tones, and minimal digital harshness.

Conversely, the GH5 II’s CMOS sensor excels in flexibility, faster readout speeds (important for video and burst shooting), and higher native ISO capability (200-25600 vs Leica’s 80-2500). Noise suppression algorithms on the GH5 II also deliver cleaner images in dim conditions, albeit with a slight tradeoff in pure color depth compared to the M9.

Dynamic Range and Color Depth

DxOMark benchmarking gives the Leica M9 a color depth of 22.5 bits and dynamic range of 11.7 EV stops. The GH5 II scores better with 23.7 bits in color depth and 13.1 EV dynamic range, highlighting its ability to handle both vibrant and shadow details with greater latitude.

For photographers who push files in post-processing or capture HDR landscapes, the GH5 II’s sensor offers more flexibility. However, diehard Leica enthusiasts may prefer the M9’s unique CCD signature and deliberate workflow that often requires less “fixing” and more intent during capture.

Autofocus and Speed: Manual Legacy Meets Modern Tracking

The Leica M9 is strictly manual focus, featuring no autofocus assistance whatsoever. This requires a sharp eye and practiced hand, often resorting to zone focusing or slow, attentive adjusting on the rangefinder patch.

While this may seem archaic in today’s fast-paced world, many photographers cherish the M9’s emphasis on slow craft and intentional image creation. It is a camera for the patient, the artist, and the purist.

The Panasonic GH5 II brings a comprehensive autofocus system to the table:

• 225 focus points with contrast-detection autofocus.
• Face, eye, and animal eye detection.
• Continuous autofocus modes.
• Tracking algorithms for challenging subjects.
• Post-focus and focus stacking capabilities.

This advanced AF system transforms shooting experiences in genres like wildlife, sports, and macro photography, where capturing fleeting moments quickly and accurately is paramount.

Regarding burst shooting speeds, the Leica M9 presses out 2 frames per second (fps) at best, suitable for portraits or still life but limiting for action. The GH5 II ramps this up to a speedy 12 fps, making it well-suited to capture fast sports, wildlife action, and unpredictable street moments.
