The W320’s ultracompact form constrains physical controls to a minimal set, favoring automated modes over manual intervention.

From a practical usability standpoint, the ergonomics favor the A350 for deliberate photo work requiring rapid setting changes. The W320 excels for casual users needing grab-and-go simplicity without the burden of complex menus or extensive button pressing.

Sensor Technology and Image Quality: The Core of Photographic Performance

Image quality largely hinges on sensor size, resolution, and the image processing pipeline, impacting everything from dynamic range to noise handling. This section leverages both technical specs and DxOMark sensor scores to compare capabilities.

Sensor Size and Type

The A350 incorporates a 23.6 x 15.8 mm APS-C CCD sensor, substantially larger than the W320’s tiny 6.17 x 4.55 mm 1/2.3” CCD sensor. The increased surface area of the A350’s sensor (approx. 373 mm² vs 28 mm²) provides inherent advantages in light-gathering capacity and signal-to-noise ratio.

Resolution and Dynamic Range

Both cameras offer approximately 14-megapixel resolution, with the A350 outputting a maximum image size of 4592 x 3056, slightly higher than the W320’s 4320 x 3240. Despite similar pixel counts, the A350’s larger pixels improve dynamic range and low-light performance.

• Sony A350: DxOMark reports 22.6 bits color depth and an excellent 11.5 EV dynamic range, contributing to subtle tone reproduction, highlight retention, and shadow detail.
• Sony W320: Lacks DxOMark testing but given sensor size, expect significant compromises in dynamic range and noise control.

ISO and Noise Performance

The A350’s native ISO range of 100-3200 offers usable low-light capability with moderate noise at higher sensitivities. The W320’s ISO ceiling is similar numerically but practically limited by its small sensor, producing more aggressive noise and lesser detail retention in dim environments.

Autofocus System and Imaging Responsiveness

Accurate and fast autofocus (AF) underpins every successful photograph, especially in dynamic genres like wildlife or sports.

AF Technologies and Point Coverage

• Sony A350: Employs a 9-point phase-detection AF system embedded in its DSLR mirror assembly, with options for single, continuous AF, and selective area focusing. The system, while not cutting-edge by current standards, delivers reliable speed and accuracy particularly in good lighting.
• Sony W320: Utilizes 9-point contrast-detection AF, which while accurate in still subjects and well-lit conditions, is notably slower and prone to hunting in low contrast or moving scenes.

Focus Behavior in Real-World Use

The A350’s phase-detect AF affords faster lock-on times and consistent focus in tracking modes - although it lacks advanced features like face or eye detection. The W320’s simplicity matches casual scenes best and falters with fast action or macro precision.

Display and Viewfinder: Composing with Confidence

Effective framing requires comfortable, accurate viewing aids - optical or electronic.

Rear LCD and Articulating Screens

Both feature 2.7” LCDs with 230k pixel resolution. The A350’s tilting screen is particularly useful for low-angle, high-angle, or tripod-mounted photography, enhancing usability in diverse conditions. The W320’s fixed screen limits such flexibility.

Viewfinders

• Sony A350: An optical pentamirror viewfinder providing roughly 95% frame coverage with 0.49x magnification - a standard entry-level DSLR offering providing natural and lag-free composing.
• Sony W320: No viewfinder, relying solely on the LCD in bright or outdoor light conditions, which can complicate accurate composition and framing.

Lens Systems and Photographic Versatility

Lens compatibility and available focal lengths define artistic flexibility and image character, especially crucial for enthusiasts and professionals.

Mount Types and Lens Ecosystem

• Sony A350: Features the Sony/Minolta Alpha mount, compatible with a broad range of A-mount lenses. Its 1.5x crop factor amplifies the reach of telephoto lenses, valuable for wildlife and sports photography.
• Sony W320: Fixed 26-105 mm (35 mm equivalent approx.) 4× zoom lens with moderate aperture range (f/2.7–5.7), limiting optical versatility and depth of field control.

The A350’s interchangeable-lens system opens possibilities spanning ultra-wide to super-telephoto, fast primes to macro optics, catering to all photography genres. The W320’s fixed lens confines users to a one-size-fits-all approach.

Shooting Modes and Manual Controls

Professional and enthusiast photographers demand manual exposure modes and customizable settings to tailor image capture precisely.

• Sony A350: Offers full manual, aperture priority, shutter priority, and program modes, plus exposure compensation and custom white balance. It also supports live view with contrast-detection AF, bridging DSLR traditionalism with newer conveniences.
• Sony W320: Limited to automatic shooting modes with no manual exposure or aperture priority capabilities, targeting convenience over creative control.

This defines the A350 as a more versatile tool for photographers looking to master exposure craft, while the W320 suits snapshot-oriented users.

Burst Rate and Shutter Performance

Capturing fast action hinges on shutter speed ranges and continuous shooting rates.
