Physical Dimensions and Ergonomics: Handling Experience Matters

Camera controls and handling ergonomics often shape the shooting experience as much as sensor quality or autofocus sophistication. The Fujifilm X100, announced in 2011, is a hallmark of compact DSLR-esque ergonomics, whereas the Sony RX1R II launched four years later with refinements targeting supreme image quality in a minimalist form.

Measured at 126x75x54 mm and weighing 445 g, the Fujifilm X100 strikes a balance between portability and providing substantial grip real estate for larger hands. Its magnesium alloy body feels robust, and the tactile dials for shutter speed, exposure compensation, and aperture ring on the lens encourage rapid manual adjustments. The fixed 35mm f/2 lens integrates seamlessly without protruding excessively.

By comparison, the RX1R II is more compact at 113x65x72 mm with a heftier 507 g mass primarily due to its full-frame sensor and superior optics. Although the camera body is smaller footprint-wise, the deeper thickness and weight distribution require acclimatization. Sony’s design language leans toward reducing extraneous controls, favoring a cleaner top deck which some shooters might find less immediately accessible for manual tweaks.

Both cameras abandon the multi-button approach in favor of minimalism, but the X100’s dedicated mechanical dials are preferred for direct exposure control. The RX1R II relies on customizable buttons and menus, demanding familiarity to fully exploit. Neither camera incorporates illuminated buttons, which is a limitation during low-light handheld operation.

Ergonomics verdict: Fujifilm X100 provides a more intuitive and comfortable grip with faster manual control access. Sony RX1R II is more pocketable yet requires more time to master its streamlined interface.

Sensor Technology and Image Quality: The Core Differentiator

At the heart of any imaging device resides the sensor, and here the two cameras diverge significantly.

The Fujifilm X100 features a 12.3-megapixel APS-C CMOS sensor sized at 23.6x15.8 mm (approx. 373 mm²). Its EXR processor supports efficient image rendering but is limited by the sensor’s inherently smaller pixel pitch and resolution, designed primarily for optimal JPEG processing and balanced performance rather than outright resolution dominance.

In contrast, the Sony RX1R II boasts a 42.4-megapixel full-frame BSI-CMOS sensor (35.9x24 mm, approx. 862 mm²) - over twice the surface area and an enormous resolution increase. This sensor pushes the boundaries of large sensor compact cameras and integrates the renowned BIONZ X image processor capable of extracting exceptional image details with impressive dynamic range.

Measured sensor metrics corroborate this advantage:

Both cameras omit an optical low-pass filter to enhance resolution but at the cost of increased moiré risk, a trade-off managed by each manufacturer’s image processing.

The RX1R II achieves superior color depth and dynamic range, especially visible in raw files, allowing for greater flexibility in post-processing highlights and shadow recovery. Its back-side illuminated (BSI) sensor design confers excellent low-light sensitivity, reflected in the much higher low-light ISO score endorsing cleaner images at higher ISOs.

For many users, the X100’s 12 MP might feel limited for large print or extensive cropping, whereas the RX1R II delivers studio-grade detail that challenges many DSLRs.

Autofocus System: Precision versus Coverage

Autofocus (AF) performance is critical across photographic genres, particularly for moving subjects.

The Fujifilm X100 carries a contrast-detection AF system with 49 selectable points. Contrast detection remains precise but slower and more prone to hunt in low-contrast or low-light situations, which affects responsiveness for moving subjects and in video modes. It supports single and continuous AF modes but does not offer predictive tracking or face/eye detection autofocus, limiting its utility in portrait work or sports.

On the other hand, the Sony RX1R II integrates a hybrid AF system combining phase-detection and contrast detection with 25 AF points, enabling faster acquisition and better tracking capability, including predictive AF. Eye-detection autofocus improves portrait results, locking onto human eyes even at wide apertures for sharp focus on critical facial features. However, the number of AF points is relatively sparse compared to modern mirrorless systems, impacting compositional flexibility. Continuous AF is not available, which restricts effectiveness for fast action photography.

Sony’s AF algorithms proved notably more adept during field tests, delivering quicker focus lock and better tracking of moderately paced subjects, particularly in brighter conditions. The X100’s AF occasionally lagged in demanding scenarios.

Display and Viewfinder: Interface and Composition Tools

Image framing and reviewing results hinge on display quality and viewfinder sophistication.

The Fujifilm X100 sports a fixed 2.8-inch TFT LCD screen with 460,000 pixels - a modest resolution by today’s standards but decent brightness and contrast. This screen does not support touch input or tilting, limiting flexible angle shooting and direct menu navigation. Its utility for detailed live view or reviewing shots is therefore constrained.

Conversely, the Sony RX1R II offers a larger 3.0-inch tilting screen with a much higher 1,229,000 dot count, providing excellent detail and usability outdoors. Though it lacks touch capability, the tilt function caters well to low or high angle shooting scenarios.

Both cameras provide electronic viewfinders (EVF), but differ substantially:

• Fujifilm X100 uses a hybrid tunnel-viewfinder combining an optical viewfinder with an electronic overlay at 1,440 pixels resolution and 0.5x magnification, covering approximately 90% of the frame. This unique design gives a rangefinder-style shooting experience, favored by street and reportage photographers who prefer optical clarity with overlayed focus or exposure data.

• Sony RX1R II features a purely electronic OLED viewfinder with 2,359,000 pixels and 0.74x magnification, covering 100% of the frame. This EVF offers a crisply detailed, parallax-free framing experience enabling precise composition and focus confirmation, especially valuable given the high-resolution sensor.

While Fuji’s hybrid finder is charming and distinct, it is somewhat limited by its coverage and magnification compared to Sony’s EVF, which is markedly more immersive and versatile, especially critical at high resolution.
