It all begins with the body: the Sony A6600 (left) asserts its presence as a robust mirrorless system, while the W320 (right) embraces pocket portability.

Physical Design and Handling: From Pocketable to Pro-Ready

Starting with pure ergonomics - the Sony A6600 is a rangefinder-style mirrorless camera boasting a solid build with dimensions around 120x67x69 mm and a weight of 503 grams including battery. This feels substantial yet balanced in hand, thanks largely to its pronounced grip and thoughtfully arranged controls geared for longer shoots and professional handling.

In stark contrast, the Sony W320 is a tiny ultracompact: just 93x52x17 mm and tipping the scales at a mere 117 grams. Its ultralight, slim profile screams convenience - ideal for pocket carry and casual snapshots. However, the diminutive size inevitably means compromises in grip comfort, control real estate, and customizability.

While the A6600 features a tilting 3-inch touchscreen and an electronic viewfinder with 2.36 million dots that offers eye-level framing precision, the W320 only has a fixed 2.7-inch LCD with a low 230k dot resolution and lacks any viewfinder altogether, pushing users towards composing via LCD in bright daylight, which can be challenging.

From a handling perspective, these cameras are at opposite ends of the spectrum - one demanding intentionality, the other embracing spontaneity. If you prize tactile dials, customizable buttons, and weather-sealed robustness, the A6600 is your playground. Conversely, if you want an everyday carry that’s fuss-free and pocket-friendly, the W320 fits the bill.

Sensor and Image Quality: APS-C Power vs. Compact Convenience

Under the hood, the Sony A6600 employs a 24MP APS-C CMOS sensor (23.5 x 15.6 mm), paired with Sony’s Bionz X image processor - the same lineage found in many professional-grade cameras. This sensor size is over 13 times larger than the W320’s 1/2.3-inch CCD sensor (6.17 x 4.55 mm), yielding vastly superior image quality, noise control, color fidelity, and dynamic range.

Large sensor dominance: The A6600’s APS-C sensor (left) dwarfs the compact W320 sensor (right), translating to superior image quality and creative flexibility.

What does this mean practically? In daylight, the W320 can produce decent snapshots for social sharing. However, the A6600’s larger pixels and superior noise handling translate to crisp, low-noise images even in challenging light. Its dynamic range score of 13.4 EV (according to DXOMark) ensures details are retained in shadows and highlights - a critical advantage for landscape and portrait photographers. The W320, designed for convenience, cannot compete here; its sensor struggles with noise at ISO beyond 400 and crushes shadows easily.

The inclusion of RAW shooting on the A6600 is a game-changer for professionals and enthusiasts who want extensive post-processing latitude. The W320 only offers JPEG, limiting image edits.

Autofocus and Shooting Performance: Precision and Speed vs. Simple Point-and-Shoot

The autofocus (AF) system on a camera often makes or breaks its utility for action, wildlife, and portraiture. The A6600 excels with Sony’s hybrid 425-point phase-detection + contrast-detection AF system, which supports:

• Real-time Eye AF for humans and animals
• Fast continuous tracking at 11 fps burst shooting
• Touchscreen AF point selection
• Reliable low-light AF down to -2 EV

During my hands-on tests in dynamic environments, the A6600 locked focus instantly, consistently tracking moving subjects - whether a fast-running dog or a bustling basketball game. The eye-detection AF is impressively accurate, keeping the subject’s eyes tack sharp, a must-have for portrait work.

By contrast, the W320 offers basic contrast-detection AF with only 9 focus points, no face or eye detection, and single shot shooting only. While adequate for stationary subjects under good light, it can struggle with hunting focus or tracking moving targets.

This gulf is apparent in burst mode performance - the A6600 handles 11 fps, enabling photographers to seize decisive moments in sports or wildlife; W320 remains stuck at single-frame capture.

Display and Viewfinder: Composing Your Shot with Confidence

The Sony A6600’s tilting 3.0-inch touchscreen LCD with 922k dots grants fine composition control, along with quick menu navigation and AF area selection - features I found indispensable when shooting in varied shooting positions or using manual focus lenses. Coupled with a bright 2.36M dot OLED electronic viewfinder with 0.71× magnification and 100% coverage, it provides a crystal-clear preview unaffected by ambient light, crucial for precise exposure control and framing.

The W320’s 2.7-inch fixed LCD with just 230k dots feels dated and offers limited clarity. The absence of any viewfinder means that bright sunlight can wash out the screen, making composition and review tricky.

A clear winner: A6600's high-res tilting touchscreen (left) versus Sony W320's modest fixed LCD (right).

For any serious photography, being able to trust your framing and focus preview is vital, placing the A6600 leagues ahead.
