A Tale of Two Designs: Ergonomics and Body Characteristics

At first glance, the Ricoh GXR Mount A12 and Sony A390 depart sharply in form factor and design ethos. The GXR’s rangefinder-style mirrorless body boasts compactness and minimalist controls, measuring a modest 120x70x45mm and weighing a light 370g. In contrast, the A390’s DSLR design sprawls at 128x97x86mm with heftier ergonomics, tipping scales at 549g.

Ricoh adopts a fixed lens mount system, limiting flexibility but benefiting from a streamlined build that enhances portability - ideal for street or travel photographers who value discretion and ease of carry. Sony utilizes the Alpha Minolta A-mount lens ecosystem (with an impressive 143 lenses available during the A390’s release), offering vastly more creative versatility for focal range and lens functionality.

The GXR’s fixed 3-inch fixed LCD panel, without touchscreen or articulating capabilities, contrasts with Sony’s smaller but tilting 2.7-inch screen. While the GXR opts for a sleek, uncluttered rear layout conducive to swift manual control, the A390 provides a more traditional DSLR button-dense interface with a prominent pentamirror optical viewfinder covering 95% of the frame and magnification of 0.49x. This gives a tangible advantage to the Sony in bright-light framing and classic photographer engagement.

Both cameras maintain manual focusing options, but the GXR’s lack of autofocus points arrangement and the Sony’s modest nine-point phase-detection AF system reflect their entry-level status, albeit approaching AF from different technical foundations.

Imaging Foundations: Sensor Technology, Resolution, and Image Quality

Sensor Type and Size

The Ricoh GXR Mount A12 features a 12MP APS-C size CMOS sensor measuring 23.6 x 15.7 mm, an ample sensor area of roughly 370.52 mm² enabling good light gathering. The Sony Alpha A390 employs a similar APS-C-sized CCD sensor (23.5 x 15.7 mm, 368.95 mm²) but with a slightly higher resolution of 14MP, yielding a maximum image dimension of 4592 x 3056 pixels versus the GXR’s 4288 x 2848 pixels.

The choice of CMOS (GXR) versus CCD (A390) significantly impacts each camera’s image character and performance. CMOS sensors generally offer better high ISO noise control and faster readout, enhancing burst speed and video capabilities. CCD, while historically lauded for color depth and tonal subtleties, tends toward higher noise at elevated ISOs and slower processing - a critical consideration for low-light and action photography.

Native ISO Range and Noise Performance

Both cameras share a maximum native ISO of 3200, but the GXR’s CMOS sensor architecture offers superior noise characteristics at higher ISO settings compared to Sony’s CCD sensor, which according to DxO Mark testing scores a low-light ISO rating of 607 (versus CMOS-class sensors in modern models scoring substantially higher). The difference in noise handling directly translates into cleaner night skies, higher ISO portraits, and better usability in poorly lit sports environments.

Dynamic Range and Color Depth

While DxO scores are unavailable for the Ricoh GXR A12 (not tested), the Sony A390 achieves a respectable color depth of 22.5 bits and dynamic range of 11.5 EV stops - solid for its time and competitive within the entry-level DSLR category. These factors influence highlight retention in landscapes and subtle midtone gradation for portrait skin tones, areas where both cameras perform competently but with the Sony generally edging ahead due to its higher resolution and robust image processing pipeline.

Autofocus and Shooting Responsiveness: Capturing the Moment

Both cameras provide basic autofocus functions tailored to entry-level users, with similar continuous shooting speeds of about 3fps, which, while not suited for professional sports or wildlife photography, suffice for casual shooting and slower action.

Autofocus Technology Comparison

The Sony A390 integrates a phase-detection autofocus system with nine selectable points. Phase detection delivers faster, more accurate focusing in daylight or well-lit scenes and supports face detection autofocus - a boon for portrait and live event shooting. This AF system allows users to track subject movement with reasonable precision, though not at professional-grade responsiveness.

The Ricoh GXR Mount A12 instead offers contrast detection autofocus, which is inherently slower and less effective in tracking erratic subjects, compounded by no face or eye-detection capabilities. However, the GXR does include multi-area AF modes and continuous AF, preserving some versatility for static or modestly dynamic scenes. The lack of an inbuilt viewfinder (only an optional electronic viewfinder is available) paired with contrast detection poses challenges for fast-moving subjects and low-light performance.

Screen and Viewfinder Experience: Composing and Reviewing Images

The Ricoh GXR’s fixed 3.0-inch LCD panel at 920,000 dots strikes a balance for clarity and size, though the absence of touchscreen or articulating mechanisms can reduce compositional flexibility in awkward angles or street candid work.

Sony’s 2.7-inch display, despite having a much lower 230k-dot resolution, adds a tilting function allowing more adventurous framing perspectives - a notable plus for macro, low-angle, and overhead shooting. Its deeper control menu integration and physical grip on a DSLR body benefit prolonged shooting sessions in varied orientations.

Sony’s optical pentamirror viewfinder remains a hallmark of DSLR shooters, delivering real-time, lag-free, full-frame sightlines with better light transmission than electronic options commonly found in mirrorless setups of the era (like Ricoh’s optional EVF). This advantage manifests particularly in bright outdoor conditions and for photographers habituated to traditional SLR composing.

Strength in Lenses: Ecosystem and Compatibility Considerations

Lens availability significantly impacts long-term usability, system flexibility, and creative growth. The Ricoh GXR’s unconventional design locks users into proprietary fixed lens/ sensor units, effectively limiting lens interchangeability and tethering to Ricoh’s relatively niche optic lineup. While the GXR sensor modules can be swapped, the Mount A12 unit itself is fixed lens-only, curtailing versatility and potential expansion.

Conversely, Sony’s Alpha A390 leverages a mature Sony/Minolta A-mount lens ecosystem with over 140 compatible lenses spanning primes, zooms, macros, and specialized optics. This access empowers photographers to evolve their kit according to shooting genres and budgets, including third-party choices offering competitive quality and pricing.

This flexibility strongly favors the Sony for users prioritizing system longevity and diverse focal needs - particularly in portraiture, telephoto wildlife, and macro photography.

Real World Performance Across Photography Genres

To elucidate the practical implications of these specifications, this section explores the usability and image output of both cameras within key photography domains, guiding readers towards genre-specific recommendations.
