Sony W730 vs Sony A58: A Deep Dive into Practical Photography Performance for Enthusiasts and Professionals
Choosing your next camera involves balancing technical features, real-world usability, and creative potential. Today, we explore two Sony cameras from the early 2010s with drastically different categories and capabilities - the Sony Cyber-shot DSC-W730 and the Sony SLT-A58. Despite their shared brand, these cameras serve very different photographic needs. Our comprehensive comparison will clarify which camera aligns with your creative journey, whether you are a casual shooter, enthusiast, or stepping up to serious photography.
First Impressions: Size, Build, and Handling
Understanding a camera's physical characteristics is a foundational step that often influences practical use more than specs. The W730 is a pocket-friendly compact camera weighing only 122 g, measuring 93 × 52 × 22 mm - highly portable and intuitive for travel and casual shooting. In contrast, the A58 is a significantly larger entry-level DSLR-style camera, weighing 492 g with dimensions 129 × 95 × 78 mm.
This size difference reflects a major ergonomic distinction. The A58's larger grip and DSLR styling favor extended handheld shooting comfort and better control in varied conditions. However, it requires a bag and is less discreet for spontaneous moments. The W730’s minimal weight and compact frame make it perfect for slipping into any pocket or purse for on-the-go photography.
Both cameras lack environmental sealing, so extra care is needed in harsh weather for either choice.
Controls and User Interface: Simplicity vs. Creative Control
Looking at the top plate and control layouts gives us insight into how Sony designed user interaction:
-
Sony W730: Minimal physical controls, no dedicated dials for aperture or shutter priority. Its fixed lens and limited manual controls mean straightforward operation but less creative flexibility. The touchscreen LCD makes menu navigation easier, aimed at beginners wanting simple point-and-shoot functionality.
-
Sony A58: Offers dedicated dials for shutter and aperture priority modes and manual exposure, plus customizable buttons to streamline your workflow. The presence of an electronic viewfinder with 1440k dots and 100% coverage enhances composition accuracy, especially outdoors and in bright light where LCDs can be challenging to see.
The W730's design focuses on casual ease; the A58 is built for photographers ready to engage with exposure settings and advanced autofocus.
Sensor and Image Quality: Small Compact Sensor vs APS-C Powerhouse
Sensor technology directly impacts image quality, low-light performance, dynamic range, and overall photo fidelity.
Feature | Sony W730 | Sony A58 |
---|---|---|
Sensor Type | CCD | CMOS |
Sensor Size | 1/2.3" (6.17 × 4.55 mm) | APS-C (23.2 × 15.4 mm) |
Sensor Area | 28.07 mm² | 348.00 mm² |
Resolution | 16 MP | 20 MP |
Max ISO | 3200 | 16000 (native), 25600 boosted |
Raw Support | No | Yes |
Antialias Filter | Yes | Yes |
Dynamic Range (DxOMark) | Not tested | 12.5 EV |
Color Depth (DxOMark) | Not tested | 23.3 bits |
Low-Light ISO (DxOMark) | Not tested | 753 |
The Sony A58’s APS-C CMOS sensor is vastly superior, delivering better resolution, dynamic range, and high ISO performance. This large sensor excels at capturing richer details, smoother gradations, and less noise in low light. Support for RAW files also allows in-depth post-processing for professionals.
Conversely, the W730’s small 1/2.3" CCD sensor is typical for compact cameras. It’s suitable for casual use but limited for professional output - especially under challenging lighting. The maximum ISO of 3200 is usable only at low image quality standards. The lack of RAW means less control over color grading and exposure during editing.
If image quality is paramount, especially for print or professional use, the A58 is the obvious choice.
Viewing and Composition: Display and Viewfinder
Viewfinder and display systems affect your shooting experience profoundly:
-
Sony W730: Equipped with a fixed 2.7-inch touchscreen LCD with only 230k dots, an older TFT type prone to glare. No viewfinder is available, limiting shooting comfort in bright situations.
-
Sony A58: Features a tilting 2.7-inch LCD with 460k dots, offering better resolution and composition flexibility. More importantly, it sports a high-res electronic viewfinder (EVF) with 1440k dots, 100% frame coverage, and 0.65x magnification. The EVF provides stability for long lenses or tricky lighting while enabling exposure preview and settings feedback before capture.
For outdoor photographers or those shooting action or landscape, the A58's EVF combined with a tilting, higher-res LCD gives real tactical advantages in framing and shooting.
Autofocus and Burst Shooting: Tracking Action and Precision
Autofocus (AF) is crucial across genres like wildlife, sports, and street photography. Let’s break down the systems in both cameras:
Aspect | Sony W730 | Sony A58 |
---|---|---|
AF System Type | Contrast-detection only | Hybrid AF (Phase + Contrast) |
AF Points | Unknown (limited) | 15 points (3 cross-type) |
Continuous Autofocus (AF-C) | No | Yes |
Face Detection | Yes | Yes |
Animal eye AF | No | No |
Burst Rate (FPS) | 1.0 | 8.0 |
The A58’s hybrid AF system, derived from Sony’s Translucent Mirror Technology (SLT), uses phase detection autofocus for fast, reliable focusing and contrast detection for accuracy during live view. Its 15 focus points, including three cross-type sensors, enable precise tracking of moving subjects. Combined with 8 fps burst shooting, the A58 is well suited for wildlife or sports photography.
In contrast, the W730 offers a slow, single-shot autofocus system with only contrast detection and one frame per second for continuous shooting. It can handle casual portraits or landscapes but struggles with fast action or moving subjects.
If you want to capture dynamic moments - say at a soccer game or birdwatching - the A58 is the clear choice.
Lens Ecosystem and Versatility
-
Sony W730: Fixed 9× zoom lens (25-224 mm equivalent), aperture f/3.3-6.3. It cannot be changed or upgraded. Good for general snapshots but limited creative control - you won’t get very shallow depth of field or specialist lenses.
-
Sony A58: Uses Sony A-mount lenses (originally Minolta Alpha), with over 140 lenses available spanning primes, zooms, wide angles, telephotos, macro, and specialty optics. This vast ecosystem means you can tailor the camera to various genres, from stunning portraits with fast primes to long-range wildlife telephotos.
The W730 is an all-in-one package for portability. The A58 offers a path to grow your kit with excellent glass options, which is important for maintaining quality and versatility as you develop your photographic skills.
