Sony A330 vs Sony A57: A Hands-On Comparative Review for Photography Enthusiasts

As cameras evolve, so do the options available to photographers seeking an upgrade, whether starting out or aiming to balance quality and versatility without breaking the bank. Today, I’m diving deep into two entry-level Sony DSLRs from slightly different eras: the Sony Alpha DSLR-A330 (released 2009) and the later Sony SLT-A57 (released 2012). Both cameras target enthusiasts wanting solid performance and enjoyable features, but their specifications and technologies vary significantly. Drawing from my years of field testing and studio trials with hundreds of DSLRs, I’ll help you understand how these models compare in real-world usage across a wide range of photography disciplines.

First Impressions: Ergonomics and Handling

A camera’s feel in your hands directly impacts your shooting confidence and comfort during long sessions. The Sony A330, built as a compact SLR with a pentamirror optical viewfinder, feels noticeably lighter and more pocketable than the A57. The A57 adds weight (529g vs 618g) and bulk, partly because it features a more advanced Electronic Viewfinder (EVF) and fully articulated LCD.

The grip on the A57 is also more prominent and cushioned, making it easier to hold steady with longer lenses or during burst shooting. Sony’s design improvements here suggest they intended the A57 to appeal to users spending more time shooting dynamic subjects or video.

Control layouts differ too. The A57 sports more buttons and a rear thumb toggle for quicker autofocus point selection and menu navigation, useful for fast-moving subjects. The A330’s controls are simpler, which may appeal to beginners but might slow down rapid adjustments.

Summary

• A330: Lightweight, compact, simpler controls - great for casual use and travel.
• A57: Heavier, robust grip, more control options - better suited for intensive shooting and enthusiasts who like fast operation.

Sensor and Image Quality: CCD vs CMOS

One of the core distinctions is the sensor technology: the Sony A330 uses a 10MP APS-C CCD sensor, while the A57 has a 16MP APS-C CMOS sensor.

Technical Implications:

• Sensor Resolution: The A57’s 16 megapixels provide more detail, supporting larger prints and cropping flexibility.
• Sensor Technology: CMOS sensors (A57) generally offer better low-light performance, faster readout speeds, and improved dynamic range compared to CCD (A330).
• Image Quality Metrics: DxOMark scores reflect this:
  • Sony A330 overall score: 64, with 22.4 bits color depth, 11.5 EV dynamic range.
  • Sony A57 higher at 75, 23.4 bits color depth, 13 EV dynamic range, and better low-light ISO performance (rated at ISO 785 vs ISO 535).

Practical Takeaway:

From my real-world tests, the A57 produces cleaner files at higher ISOs (above 800), better shadow recovery, and richer color gradation, making it more versatile for varied lighting - especially in landscape and event photography settings.

**However, the A330’s CCD sensor tends to render images with a distinctive, pleasant color tone that some users prefer for portraiture and classic still life.

Viewfinder and LCD: Optical vs Electronic

The A330 retains a traditional pentamirror optical viewfinder with approximately 95% coverage and 0.49x magnification - familiar territory for DSLR users but with the classic limitations of not showing exposure previews or focus magnification.

In contrast, the A57 features a high-resolution 1.44-million-dot EVF offering 100% coverage and 0.7x magnification, plus a 3-inch fully articulated LCD with 921K dots and Sony’s TruBlack technology for superior contrast and outdoor visibility.

Utility in Practice:

• Optical Viewfinder (A330): Many photographers prefer optical for immediate, lag-free scene viewing, but lack previewing features.
• EVF (A57): I found the EVF a significant upgrade for critical focusing, exposure preview, and reviewing images, though some users find EVF motion less “natural” than optical.
• LCD Articulation: The A57’s articulated screen expands your compositional options for video, low-angle macros, or street photography.

Autofocus and Speed: Tracking Moving Subjects

Focusing technology sharply differentiates these models as well.

The A330 offers nine autofocus points (phase detection and contrast detection hybrid), face detection in live view, but lacks continuous tracking capabilities. Burst shooting maxes out at a modest 3 fps.

The A57 builds on this with 15 AF points (including 3 cross-type points), and more critically, incorporates continuous AF tracking and higher-speed burst shooting at 12 fps (silent mode). The A57 also uses Sony’s Translucent Mirror Technology, meaning it can autofocus continuously even during video recording or high-speed shooting without mirror blackout.

In my field tests:

• The A330’s AF performs adequately in steady conditions but struggles with erratic, fast-moving wildlife or sports.
• The A57’s autofocus is significantly more responsive and accurate for action sequences, tracking runners, cyclists, or birds, delivering more keepers in rapid bursts.

Flash and Creative Lighting

Both cameras feature built-in pop-up flashes with similar range (about 10 meters) and external flash compatibility.

However, the A57 supports more advanced flash modes like High-Speed Sync, fill-in, and wireless flash, expanding creative lighting options during tricky ambient conditions like bright sunlight or night scenes.

Video Capabilities: From Still to Motion

Here lies a standout improvement.

• Sony A330: No video recording capabilities.
• Sony A57: Offers Full HD 1080p video at up to 60fps, supported by stereo microphone input (external mic), with sensor-based stabilization working during video.

For enthusiasts blending photography and videography, the A57’s inclusion of 1080p video with AF tracking is a huge plus. In my testing, video footage was smooth and focused accurately on moving subjects, though the absence of a headphone jack limits audio monitoring.

Battery Life and Storage

The battery in the A57 nearly doubles that of the older A330 (550 shots vs 230 shots per CIPA rating). If you anticipate long days filled with continuous shooting or events, the A57’s better stamina is a tangible benefit reducing the need for multiple batteries.

Both cameras use a single memory slot; the A330 supports SD/SDHC and Memory Stick Pro Duo, whereas the A57 adds SDXC compatibility for larger, faster cards - useful for 16MP RAW and HD video files.

Durability and Weather Sealing

Neither the A330 nor A57 offer weather sealing, dust proofing, or shock resistance. For outdoor photographers, this means adding protective gear or handling with care in challenging environments.

Lens Compatibility and Ecosystem

Both models share Sony’s Alpha/Minolta A-mount with about 143 lenses currently available, spanning wide angles, telephoto, primes, and macro optics.

Sony has since shifted their focus toward mirrorless E-mount systems, but if you already own or prefer A-mount lenses, both cameras integrate seamlessly.
