Ricoh PX vs Sony SLT-A35: An Expert Comparison for Enthusiasts and Professionals Seeking Optimal Camera Choice

In the diverse universe of digital cameras, enthusiasts and professionals often face a challenging selection process when comparing cameras that fundamentally differ in category, sensor capability, and intended use. The Ricoh PX, a small-sensor compact announced in 2011, and the Sony SLT-A35, an entry-level DSLR-like interchangeable-lens camera unveiled shortly thereafter, present a compelling case study in divergent camera design philosophies and real-world operational performance. This comparison dissects these two models across core photographic disciplines, technical make-up, and practical usability, enabling an informed decision tailored to specific photographic workflows and contexts.

Understanding the Physicality: Size, Build, and Handling

One of the most immediate differentiators between these models is size and ergonomics. The Ricoh PX occupies a compact footprint (100x55x21 mm) and weighs a mere 156 grams, making it highly portable and ideal for discrete photography scenarios. Conversely, the Sony A35, although compact for a DSLR-class camera, measures a significantly larger 124x92x85 mm and weighs 415 grams, reflecting its more substantial interchangeable-lens design.

The PX's diminutiveness facilitates effortless pocketability but inevitably limits manual grip comfort and physical control layout. The A35, with its more robust grip and traditionally shaped DSLR body, supports extended shooting sessions with better stability, particularly when coupled with larger lenses. The Sony's design incorporates more physical controls and an articulating top plate, reflecting this ergonomic advantage.

Ergonomically, the A35's extensive dials, buttons, and mode wheels provide quick access to essential parameters such as shutter priority, aperture priority, and exposure compensation, catering to advanced users and demanding shooting contexts. The PX, by contrast, leans towards simplicity with minimal control interfaces and lacks certain exposure modes like shutter priority, constraining nuanced manual settings.

Sensor Architecture and Image Quality: Trade-offs Between Size and Performance

At the heart of any camera's imaging capability lies the sensor, dictating resolution, dynamic range, noise performance, and ultimately image fidelity. The Ricoh PX features a 1/2.3-inch (6.17 x 4.55 mm) CCD sensor with 16 megapixels resolution but inherently limited sensor area (~28 mm²). The Sony A35 sports a substantially larger APS-C (23.5 x 15.6 mm) CMOS sensor, also delivering 16 megapixels but with an impressive sensor area of 366 mm², over 13 times larger.

Practically, the A35 benefits from this larger surface area, affording superior dynamic range (approximately 12.7 EV vs. unreported but markedly lower on PX), enhanced color depth (23.3 bits vs. untested on PX but predictably more constrained), and far improved high ISO performance (native ISO up to 25600, with usable results beyond 1600 ISO). Users will notice that the Ricoh PX struggles in low-light environments where noise rapidly becomes intrusive beyond ISO 400–800 equivalents. The PX sensor's CCD technology, while capable of delivering relatively sharp daylight images, is somewhat dated and less sensitive than Sony’s modern CMOS on the A35.

Additionally, the A35 supports RAW capture and includes an anti-aliasing filter, enabling maximum post-processing flexibility and sharpening control unachievable with the PX’s JPEG-only output and anti-aliasing presence.

Display and User Interface: Visual Feedback and Touchpoints

The rear LCD and interface play crucial roles in contemporary shooting and image review workflows. The PX is equipped with a fixed 2.7-inch 230k-dot screen, sufficient for basic framing and menu navigation but limited in resolution and size for precise focus inspection or exposure histogram evaluation. It lacks touchscreen functionality and articulation, constraining usability in complex shooting angles.

The Sony A35’s larger 3.0-inch screen features 921k dots resolution, nearly quadruple the pixel density of the PX, offering a markedly clearer and more detailed preview. While not touch-enabled, the A35 provides live view functionality with face detection autofocus, enhancing compositional accuracy.

This superior display directly impacts critical focus accuracy, particularly in manual focus scenarios and macro or portraiture work, where sharpness at the eye or subject detail is paramount.

Optical Systems and Autofocus Performance

The Ricoh PX is fitted with a fixed 28-140mm (35mm equivalent) zoom lens with a modest maximum aperture range of f/3.9-5.4. It excels in macro with a minimum focus distance of 3 cm and employs sensor-shift image stabilization, rare for its class, which effectively reduces handheld blur. However, its autofocus system is contrast-detection based, single-point by nature, excludes continuous autofocus modes, and has a slow sequential shooting rate of 1 fps - impractical for action or wildlife photography.

The Sony A35, by contrast, utilizes an interchangeable Sony/Minolta Alpha mount lens ecosystem with over 140 compatible lenses ranging from wide-angle to super telephoto. This versatility grants professional-grade latitude by permitting users to pair fast primes, specialized macro optics, and telephoto zooms tailored to shooting genres.

Autofocus is a highlight for the A35, which employs a hybrid AF system combining 15 phase-detection points (including 3 cross-type) with contrast detection. This results in quick, accurate, and continuous autofocus tracking up to 6 fps continuous burst shooting - competent for wildlife, sports, and dynamic street photography.

Photography Genres: Situational Strengths and Weaknesses

Portraiture

Skin tone rendition and bokeh quality depend strongly on sensor size and lens aperture. The Sony A35’s APS-C sensor coupled with availability of fast prime lenses (f/1.4-1.8) produces superior subject separation and creamy bokeh, essential for flattering portraiture and effective subject isolation. The camera’s face detection AF improves eye focus accuracy, a decisive advantage in portraits.

The Ricoh PX, limited by its small 1/2.3” sensor, fixed quite slow lens, and modest AF system, delivers comparatively flat images with minimal background defocus. Its bokeh is more synthetic and less pleasing, and skin tone nuance is more prone to highlight clipping or noise in subtleties, especially in mixed lighting.
