Ergonomically, both adopt an SLR-like form factor with prominently positioned grips and control dials. Users transitioning from DSLRs or mirrorless will feel familiar, though smaller hands may find the Leica’s slightly smaller footprint more manageable.

Control Layout and Top Panel

The V-Lux 4 offers a minimalist yet effective top control layout with quick access dials enabling exposure compensation, shutter speed, and aperture adjustments - beneficial for manual exposure workflows.

Conversely, the HX400V integrates a more segmented control scheme with dedicated buttons for zoom control and video functions, reflecting Sony’s emphasis on hybrid still-video use. While less minimal, it delivers direct tactile control but at the expense of a slightly steeper learning curve.

Sensor Architecture and Image Quality

Image quality remains paramount, anchored by sensor technology, lens optics, and image processing efficacy.

Sensor Specifications

• Leica V-Lux 4: Houses a 1/2.3-inch CMOS sensor measuring 6.08 x 4.56 mm with 12 megapixels resolution (4000 x 3000). This sensor carries an antialiasing filter and native ISO range of 100-3200, expandable up to 6400. Notably, the V-Lux 4 supports RAW capture, facilitating post-processing flexibility.

• Sony HX400V: Equipped with a marginally larger 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm) boasting 20 megapixels resolution (5184 x 3888). It supports ISO 80 to 12800 (no expanded ISO) but lacks RAW support, limiting professional editing latitude.

Image Quality Nuances

Despite its lower megapixel count, the Leica’s sensor benefits from a less aggressive pixel density, improving light gathering efficiency and dynamic range in practice. The CMOS sensor’s construction yields decent color depth and noise performance up to ISO 800; noise becomes more evident beyond ISO 1600. Given the era and sensor size, neither camera’s low-light capacity matches larger-sensor cameras, but the Leica’s ability to output RAW files provides an advantage for noise reduction workflows.

The Sony, while offering higher resolution, struggles more noticeably with noise at elevated ISO speeds due to denser pixels on a small surface area. This reduces image sharpness and dynamic range under challenging lighting. JPEG files produced by its Bionz X processor are well-processed but less malleable compared to the V-Lux 4’s RAW files.

Lens and Zoom Capabilities

Lens design is pivotal in superzoom cameras, determining focal length range, aperture characteristics, and overall image fidelity.

The Leica features a moderate 24x zoom (effectively 25-600mm), with a stellar constant f/2.8 aperture throughout the zoom range. This advantage in lens speed allows markedly better low-light capability and shallower depth of field at telephoto lengths, enhancing bokeh quality and subject separation.

Sony’s HX400V garners an impressive 50x zoom lens (24-1200mm equivalent), doubling the V-Lux’s reach, albeit with a variable maximum aperture that narrows to f/6.3 at long telephoto. This compromises low-light performance and background rendering past mid-zoom lengths.

The wider aperture and shorter telephoto reach of Leica’s lens make it more suitable for portraits, events, and indoor photography where light is limited and bokeh is desired. Sony’s extended focal length better suits distant wildlife or surveillance-style shooting, albeit needing brighter environments.

Autofocus System and Focusing Performance

Focusing speed, accuracy, and tracking capabilities are critical across shooting genres, from wildlife to street photography.

Leica’s autofocus system employs 23 contrast detection points and features face detection and continuous autofocus tracking, allowing smoother subject keeping in motion - particularly useful for dynamic shooting like events and video.

Sony’s system, despite fewer AF points, incorporates selective autofocus area modes and live view autofocus, beneficial for precise composition changes. However, its lack of continuous autofocus during burst or video limits its utility in fast action.

In real-world testing, Leica’s AF locks are quicker and more reliable, especially in low contrast or complex scenes. Sony’s autofocus tends to hunt more frequently under such conditions. For wildlife and sports, Leica’s continuous AF is a decisive advantage.

Display and Electronic Viewfinder

Good composition monitoring tools significantly affect usability.

Both cameras use electronic viewfinders (EVF) with approx. 100% coverage. Leica's EVF offers higher resolution (1312 pixels count) compared to Sony’s unspecified but lower resolution EVF, delivering a more detailed, natural preview.

Rear LCDs measure identically at 3 inches but differ in resolution:

• Leica V-Lux 4: 460k dots, fully articulated Free-Angle TFT LCD, facilitating shooting from unconventional angles including selfies.
• Sony HX400V: Higher resolution 921k dots, but a tilting screen rather than a fully articulated one, restricting extreme-angle flexibility.

While Sony’s screen is sharper, Leica’s articulation is more versatile for macro, overhead, or low-angle compositions.

Continuous Shooting and Burst Rate

Useful for action and wildlife photography, burst speeds determine capture opportunities.

• Leica V-Lux 4: Up to 12 fps continuous shooting.
• Sony HX400V: Up to 10 fps.

Though the difference is slight numerically, Leica’s faster burst coupled with continuous AF can yield more in-focus action sequences, advantageous in sports and wildlife scenarios. Sony’s 10 fps lacks continuous AF, meaning only first frame guaranteed sharpness when tracking subjects in motion.
