Before digitizing photons, a camera must feel right in the hand. The physical form factor influences comfort especially on long shoots and impacts usability of controls.

Sony A330 - This compact DSLR sports a traditional SLR layout with a deeply contoured grip that comfortably accommodates hand sizes typical of enthusiast photographers. Its dimensions (128 x 97 x 71 mm) and weight (529g) place it firmly in the lightweight DSLR category while preserving solid build integrity - though it lacks weather sealing, a common omission at this price point and era. The tilting 2.7-inch LCD, though modest by today’s standards, adds compositional versatility for awkward angles.

Sony HX20V - Designed as a pocketable compact superzoom, the HX20V prioritizes portability with a svelt 107 x 62 x 35 mm chassis weighing just 254g - less than half the A330’s heft. The smaller dimensions render it ideal for travel and street shooters craving discretion. It boasts a fixed 3-inch XtraFine TruBlack LCD with a higher resolution (922k dots), delivering crisper live view framing despite the lack of a viewfinder.

Sensor Architecture and Image Quality: A Clash of Sensor Generations

The heart of any camera is its sensor. The A330’s APS-C CCD contrasts sharply against the HX20V’s diminutive 1/2.3" BSI-CMOS sensor, setting the stage for different performance envelopes.

Sony A330: APS-C CCD Performance

With a 23.5 x 15.7 mm APS-C sensor and a 10-megapixel resolution capped at 3872x2592, the A330 employs a CCD sensor - an older but proven technology prized for delivering excellent color depth (measured at 22.4 bits by DxOMark) and a remarkable dynamic range (11.5 EV). Its use of a sensor-based image stabilization compensates for small camera shake, a notable feature given its manual-focused lens mount compatibility.

In practical terms, this means images show vibrant, nuanced color rendition and a commendable ability to retain highlight and shadow details - critical for landscape and portrait photographers seeking rich tonal gradation.

Sony HX20V: Small Sensor but High Resolution

On the flip side, the HX20V’s 1/2.3-inch BSI-CMOS sensor measures a mere 6.17 x 4.55 mm but boasts a detailed 18MP resolution (4896x3672 pixels). While increased pixel count can lend itself to fine detail in optimum lighting, the physically smaller sensor area (28.07 mm²) limits low-light performance and dynamic range, areas where noise can intrude from ISO 800 upwards.

The BSI (Backside Illuminated) design somewhat mitigates these compromises by enhancing light sensitivity and improving signal-to-noise ratios relative to traditional CMOS sensors. This results in respectable noise control for a superzoom compact, though still trailing the larger APS-C chips under challenging illumination.

Autofocus Systems and Speed: Tracking and Accuracy at Work

Autofocus (AF) performance dramatically affects how well a camera can capture fleeting moments - vital for sports, wildlife, or street photography.

Sony A330: Hybrid Phase-Detection with 9 AF Points

Featuring a nine-point hybrid AF system incorporating both contrast and phase detection, the A330 aligns with DSLR expectations of 2009. It offers continuous AF and face detection live view modes, albeit lacking the sophisticated tracking algorithms present in more recent models. Its AF is reliable for portraits and general photography but can falter in fast-paced subjects due to less advanced tracking.

Sony HX20V: Contrast-Detection and Face Tracking

The HX20V relies solely on contrast-detection AF with nine points and enhanced face detection, alongside AF tracking capabilities, albeit without phase detection. Its continuous shooting rate spikes to a respectable 10 fps - an attractive spec for action photographers using a superzoom compact.

However, contrast-based AF tends to be slower and less predictive than phase detection, leading to occasional hunting in low light or moving subjects. Still, the incorporation of comprehensive AF regions and tracking reflects Sony’s calibration for user-friendly operation in a compact body.
