At first glance, the Nikon Z6 II and Sony RX100 III couldn’t be more different in size and intended handling.

• Nikon Z6 II: A full-frame mirrorless shooter with an SLR-style body weighing 705g, dimensions 134×101×70mm, it feels substantial and built for serious use. The grip provides excellent control for prolonged shooting, and the camera balances well with heavier professional lenses.
• Sony RX100 III: A pocketable large-sensor compact at 290g and compact dimensions of 102×58×41mm, it slips easily into a jacket or pocket. It’s designed for photographers who want quality in a highly portable form.

This size difference affects everything: handling stability, presence when shooting, and portability for travel or street photography.

My testing proved the Z6 II’s robust build excels in long shoots and professional settings, delivering reassurance through its heft and grip. Meanwhile, the RX100 III thrives as a grab-and-go tool where stashed-away convenience beats bulk.

The Nikon Z6 II features a traditional DSLR-esque button and dial layout with a top LCD panel that quickly communicates settings - a boon for pros who adjust exposure parameters on the fly. The touchscreen tilting LCD adds flexibility, especially for video or creative angles.

The RX100 III compensates for its size with a more minimalist control scheme: fewer customizable buttons and no touchscreen, but a well-placed control ring around the lens for quick aperture changes without diving into menus.

If you prize control access and tactile feedback, the Z6 II impresses. The RX100 III leans on simplicity and speed in compact form.

Sensor and Image Quality: Full-frame vs 1-Inch Sensor Dynamics

The heart of any camera is its sensor, and here Nikon and Sony are worlds apart:

• Nikon Z6 II: Full-frame BSI CMOS sensor, 25.3MP resolution delivering 6048×4024 pixel files, sensor area 858.01 mm².
• Sony RX100 III: 1-inch BSI CMOS sensor, 20.1MP effective resolution, 5472×3648 pixel files, sensor size 13.2×8.8mm, sensor area 116.16 mm².

Real-World Impact:
The Z6 II’s significantly larger sensor captures more light, providing superior low-light sensitivity, wider dynamic range, and shallower depth of field control - essential for professional landscape, portrait, and night photography where image quality is paramount.

The RX100 III’s smaller sensor still punches above its weight for a compact. In good light, it produces sharp, pleasing images, but noise becomes evident above ISO 800-1600, and dynamic range compression limits shadow recovery compared to the Z6 II.

I repeatedly found on location that the Z6 II outperformed in shadow details and highlight retention - a critical advantage when capturing challenging lighting or astrophotography scenes.

Viewing Experience: EVFs and LCD Screens Compared

• Nikon Z6 II: 3.2-inch tilting touchscreen LCD with 2.1 million dots and a bright 3.69 million-dot OLED electronic viewfinder with 0.8x magnification and 100% coverage.
• Sony RX100 III: 3-inch tilting LCD with 1.23 million dots, and an electronic viewfinder offering 1440-dot resolution and 0.59x magnification.

The Z6 II’s large, bright EVF is a joy, especially in bright sunlight or fast-action scenarios, where precise focus confirmation is vital. The touchscreen drastically improves usability, letting you tap to select focus or navigate menus swiftly.

The RX100 III’s EVF and LCD, while smaller and of lower resolution, are excellent for a compact - Bright enough and responsive, but you might struggle in intense daylight or with detailed manual focusing.

For critical tasks like portrait sessions requiring eye AF precision or nighttime framing, I lean heavily on the Z6 II’s superior viewfinder.
