I will also break down sensor technology, autofocus mechanics, ergonomics, and connectivity, weaving in relevant comparison images for grounded illustration. Whether you are an enthusiast eager to step up from basic compacts or a professional considering secondary kit, this comprehensive comparison will empower your decision.

A Tale of Two Designs: Physicality and Build

Sony’s HX1 and A35 strike immediately different impressions on the table due to their design philosophies and purposes. The HX1 is a bridge camera styled after an SLR, housing a fixed 20x superzoom lens, while the A35 embraces the compact DSLR form factor tailored to accommodate Sony’s Minolta Alpha lens mount with interchangeable optics.

Handling and Ergonomics

The HX1, weighing around 544g and measuring 115x83x92mm, feels substantial but manageable for travel or casual shooting. Its heft derives mostly from the embedded zoom lens and optical image stabilization mechanism, which coupled with a rotating 3-inch tilting LCD (albeit with low 230k-dot resolution), offers a decent balance - though the ergonomics lean toward casual shooters rather than professionals who value robust tactile control.

In contrast, the A35 is notably lighter at 415g (body only) with a slightly bulkier footprint of 124x92x85mm, thanks largely to its larger APS-C sensor coordinator and more traditional DSLR grip design. The fixed 3-inch rear screen at 921k dots offers substantially better visual clarity and fixed viewing angle compared to the HX1, making framing and reviewing images more pleasant and precise.

Looking from above, both cameras demonstrate competent layout designs, but the A35 shows a more mature, photographer-centric control system.

The A35 features dedicated dials for shutter speed, aperture, and exposure compensation, along with clearly marked buttons for ISO and white balance adjustments. The HX1 keeps things simpler, tailored for quick superzoom usage but lacks customizable controls and has a lower screen resolution, affecting interface responsiveness and detail feedback.

Ergonomics Verdict: If you prioritize tactile control, clear viewing, and flexibility for interchangeable lenses, the A35 dominates. The HX1, while well balanced for its niche, feels dated and less capable for prolonged or professional use.

Sensor Technology and Image Quality: The Heart of the Matter

Arguably, the sensor defines the camera’s core imaging potential. Here, the differences could not be starker.

Sensor Size, Resolution, and Performance

• Sony HX1: Utilizes a 1/2.4” CMOS sensor measuring just 6.1x4.6mm (approx. 27.9mm² sensor area), rendering images at a modest 9-megapixels max resolution (3456x2592). The small sensor limits dynamic range and noise performance, capped at ISO 3200 but most usable images come from ISO 125-400. The sensor includes an anti-aliasing filter to prevent moiré.

• Sony A35: Employs a significantly larger APS-C sized CMOS sensor at 23.5x15.6mm (366.6mm² sensor area), packing 16 megapixels (4912x3264) with no anti-aliasing filter, targeting ultimate sharpness and detail retention. Native ISO expands up to 25600 with a practical upper limit nearer 1600-3200 for quality. This sensor performs far better in low light and showcases superior dynamic range capabilities.

Real-World Image Quality Insights

The A35’s sensor size advantage translates to tangible benefits - cleaner images at high ISO, greater ability to capture subtle tonal gradations in shadows and highlights, and superior resolution for cropping or large prints. The HX1’s smaller sensor leads to noticeable noise at ISO 800 and limits its utility for professional-level detail or post-processing flexibility.

For photographers invested in image quality - particularly those who print large, shoot raw, or demand clean low-light outputs - the A35’s sensor is a game-changer.

Autofocus Systems and Speed: Precision vs Simplicity

Automatic focusing remains a critical concern, especially for moving subjects or dynamic shooting scenarios.

HX1: Contrast-Detection Focus

The HX1 utilizes a contrast-detection AF system with 9 focus points arranged primarily in the center. Being a fixed-lens bridge camera, it relies on the slower, less specialized contrast system, which results in slower acquisition times and reduced accuracy for fast-moving subjects. It lacks face detection and tracking, features which are standard in more modern or advanced cameras.

A35: Hybrid AF with Phase Detection

The SLT-A35 marked one of Sony’s early attempts at combining phase detection AF with live view, distributing 15 AF points (including 3 cross-type sensors) and supporting face detection for improved subject recognition. With sensor-based stabilization, the AF is more responsive, accurate, and capable of continuous AF during video recording or burst shooting (6fps max).

The A35’s autofocus performance is far superior for action, wildlife, or sports photography, as it enables faster, more reliable focus tracking and reduces missed shots.

Optics and Lens Ecosystem: Fixed vs Interchangeable

HX1 comes with a fixed 28-560mm (35mm equivalent) lens with an aperture range of f/2.8-5.2, boasting a very versatile zoom for casual everyday to wildlife-like scenarios without changing lenses. The macro focus capability down to 1cm is impressive for close-up work anywhere.

However, the optical design is a compromise - image quality, especially at telephoto extremes, can degrade, and aperture limitations hinder low-light performance and bokeh quality.

A35 employs Sony’s Alpha mount, compatible with 143+ native lenses ranging from fast primes to super-telephoto zooms. The significant flexibility permits tailored selection optimized per genre (e.g., portraits with 85mm f/1.8, landscapes with ultra-wide zooms, wildlife with 300/400mm zooms). Sensor-based stabilization aids every lens in the lineup resistant to mechanical vibration.

This lens ecosystem capacity coupled with better sensor performance grants the A35 the clear advantage for enthusiasts prioritizing optical quality, creative control, and future upgrades.

Shooting Experience and Practical Use

Display and Live View

The HX1’s 3-inch tilting 230k-dot LCD is useful for high/low angle compositions but low resolution makes image review and menu navigation less detailed. The A35’s fixed 3” screen with 921k dots is more refined, facilitating sharp previews and easier on-screen focus confirmation.

Viewfinder Quality

Being a bridge camera, the HX1 uses a basic electronic viewfinder (resolution unspecified), sufficient for framing but lacking the clarity and color fidelity of DSLRs.

The A35 employs a high-res (1150 dot) electronic viewfinder with 100% coverage and 0.73x magnification, providing a bright, accurate view that benefits manual focusing and critical scene assessment.
