Olympus TG-810 vs Sony A230: A Hands-On, In-Depth Camera Comparison for Serious Enthusiasts

When faced with choosing a camera, photographers often weigh rugged portability against image quality and creative control. Today, I’m putting two very different cameras head-to-head: the Olympus TG-810, a tough, waterproof compact designed to take a beating, and the Sony Alpha DSLR-A230, an entry-level DSLR geared toward those stepping up from point-and-shoots into a more serious photographic experience. Both offer unique benefits, but which one is right for your style and shooting needs? Drawing on my extensive testing experience with hundreds of cameras, I’ll give you a fully informed, practical assessment - not just specs on paper.

First Impressions: Size, Build, and Handling

From the outset, these cameras couldn’t be more different physically. The Olympus TG-810 is a compact, pocketable, ruggedized waterproof camera measuring just 100x65x26mm and weighing a mere 215 grams. Its tough exterior with environmental seals makes it dustproof, shockproof, waterproof (up to a depth allowing serious underwater use), and freezeproof. The Sony A230, by contrast, is a traditional compact SLR at 128x97x68mm and 490 grams, resembling a mini studio camera with a bulkier grip and a full DSLR interface. While not weather-sealed, its vintage design and heft give a reassuring grip for precise shooting.

In terms of ergonomics, the TG-810's controls are minimal and straightforward, optimized for quick point-and-shoot action in adventurous settings. The Sony DSLR’s extensive control dial, buttons, and deeper grip cater more toward deliberate photographic control. If you’re used to manual dials and exposure buttons, A230 feels like home. Both cameras have fixed LCDs, but the TG-810’s 3” TFT Hypercrystal III screen (920K dots) offers noticeably higher resolution and sunlight visibility compared to the Sony’s 2.7” 230K pixel display.

The TG’s lack of a viewfinder means relying on the LCD for composition, less ideal under bright daylight, whereas the A230 boasts an optical pentamirror (95% coverage), helpful for outdoor use. For travel photographers or underwater adventurers who prize a compact, weatherproof build, the TG-810 wins hands down; for those focusing on ergonomics and precision, the Sony DSLR feels more professional.

Sensor Technology & Image Quality: Compact vs APS-C DSLR

The heart of any camera is its sensor. The TG-810 uses a small 1/2.3” CCD sensor (6.17x4.55mm), typical for rugged compacts. It packs 14 megapixels but with the inherent limitations of compact sensor physics - more noise at high ISO, less dynamic range, and relatively limited resolution for large prints or heavy cropping.

In contrast, the A230 utilizes a significantly larger APS-C-format CCD sensor (23.5x15.7mm), also CCD-based, but almost 13 times the sensor area of the Olympus. This translates directly to superior image quality: notably better color depth, wider dynamic range, and cleaner images at ISO 100-3200. Despite the Sony’s lower pixel count at 10 megapixels, the larger sensor area means better light gathering, improved signal-to-noise ratio, and sharper, more detailed images especially when paired with quality lenses.

The Sony’s sensor also supports RAW capture, granting photographers complete control over post-processing exposure, white balance, and noise reduction - something the Olympus compact doesn’t offer, which limits the latter to JPEG output only. For photographers who want ultimate control over image quality and printing potential, the Sony A230 is a clear winner.

Autofocus and Speed: Agile Focus Meets Versatile Tracking

My tests show the TG-810 excels in rugged environments but its autofocus comes with compromises common to point-and-shoot sensor systems. Its 5× optical zoom (28-140mm equivalent) relies on contrast-detection focusing with face detection capability. It’s fast enough for casual capture but struggles with moving subjects or low-contrast scenes.

Sony’s A230 features a 9-point phase detection autofocus system inherited from Minolta SLR designs, enabling quicker, more precise autofocus with continuous AF during shooting and selectable AF areas - far more professional tools. While it lacks advanced tracking modes found in newer cameras, its AF speed and accuracy for portraits, landscapes, and even moderate sports scenarios are surprisingly competent.

Continuous shooting rates further separate them: the Sony delivers up to 3 frames per second, usable for capturing action sequences, whereas the TG-810 tops out at a single frame per second - adequate for leisurely snapshots but not for wildlife or sports action.

Image Stabilization: Sensor-Shift Advantage on Olympus and Sony

Both cameras incorporate sensor-shift image stabilization, a key feature for handheld shooting. The Olympus TG-810’s stabilization is effective in minimizing blur, especially at telephoto zoom lengths and low shutter speeds, a critical benefit underwater or in dim lighting.

Sony’s sensor-based stabilization on the A230 works well across a broader lens range, particularly beneficial when paired with telephoto and macro lenses where camera shake magnifies. During my field shoots, both proved valuable, but the Sony’s system offers more flexibility thanks to interchangeable lenses.

Exposure Control and Creative Flexibility

The TG-810’s simplicity comes at the cost of creative control. It lacks manual exposure modes, shutter priority, or aperture priority settings. Photographers are confined to automatic exposure with limited white balance settings and no ability to bracket or customize exposure compensation.

Meanwhile, the A230 supports full manual exposure control along with aperture and shutter priority modes, exposure compensation, and custom white balance, appealing to enthusiasts and learners who want to develop their skills or have specific creative requirements. In portrait or landscape situations, this control allows more intentional rendering of images.

Lens Ecosystem and Compatibility

Perhaps the most decisive factor for many buyers is lens versatility. The TG-810’s fixed 28-140mm equivalent lens covers a useful focal range but cannot be swapped or upgraded. While this “all-in-one” zoom provides compact convenience, optical performance lags behind prime or professional zoom lenses.

Sony’s A230, with its Sony/Minolta Alpha A-mount, accesses a vast library of over 140 compatible lenses, including fast primes, macro, tilt-shift, telephoto, and zooms tailored for every photographic discipline. This ecosystem advantage alone architectures significant longevity and creative growth potential.

Shooting Genres: Strengths and Limitations Across the Board

Let me share insights based on real shooting scenarios to help illustrate the best use cases for both these cameras.

Portrait Photography

• Olympus TG-810: Face detection autofocus helps with framing people casually, but limited aperture control (f/3.9-5.9) and fixed zoom restrict depth-of-field control and background blur. Skin tones render decently but somewhat flat due to JPEG processing and sensor limitations.
• Sony A230: Greater sensor size, custom white balance, and manual exposure enable richer, more natural skin tones and beautiful bokeh when paired with fast lenses (e.g., 50mm f/1.8). The DSLR’s 9-point AF and center-weighted metering aid precise focus on eyes.
