Olympus SH-3 vs Sony A390: A Hands-On Comparison for the Discerning Photographer

Choosing a camera that meets your photography needs is never a straightforward task, especially when faced with two very different models like the Olympus Stylus SH-3 and the Sony Alpha DSLR-A390. One is a compact superzoom with a fixed lens and modern features, the other an entry-level DSLR carrying the legacy of interchangeable lenses and traditional controls. Having spent weeks extensively testing both in the field, I want to share my detailed findings, helping you decide which camera suits your style, budget, and photographic ambitions.

Let’s dive in.

Size, Handling, and Ergonomics: Portability Meets Substance

Handling is one of those factors that subtlety influences your overall photography experience more than you might imagine. The Olympus SH-3 is a compact superzoom designed for portability - its dimensions measure a mere 109 x 63 x 42mm and it weighs just 271 grams. In contrast, the Sony A390, an entry-level DSLR, is a substantially larger and heavier camera, measuring 128 x 97 x 86mm and weighing 549 grams.

The Olympus slips easily into a jacket pocket or small bag, making it an appealing choice for travel and spontaneous street shooting. Its fixed 25-600mm equivalent lens covers an impressively broad range, cutting down the need for multiple lenses. On the other hand, the Sony’s DSLR build affords a more substantial grip and a reassuring heft that many photographers appreciate for stability, especially for longer shoots or telephoto work.

Looking at the top plate and control layouts, the Olympus has a minimalistic design with a few buttons and a mode dial, optimized for quick access but limiting granular manual control. The Sony A390 shines here with a conventional DSLR interface complete with dedicated dials for shutter and aperture priority modes, plus a traditional optical viewfinder - something the Olympus lacks.

For photographers who prefer physical controls and the tactile engagement of a DSLR, the Sony takes the crown. However, those favoring discretionary shooting with easy-to-navigate touchscreen controls will appreciate what Olympus offers here.

Sensor Tech and Image Quality: Size Matters

Arguably the most profound difference between these cameras lies in their sensor technology and resulting image quality. The Olympus SH-3 employs a 1/2.3-inch BSI-CMOS sensor measuring 6.17 x 4.55 mm with a 16-megapixel resolution. The Sony A390 features a significantly larger APS-C sized CCD sensor at 23.5 x 15.7 mm with 14 megapixels.

In practical terms, the APS-C sensor’s surface area is more than ten times larger than the Olympus's, which directly translates into superior image quality across the board. Larger sensors collect more light, aiding better low-light performance, greater dynamic range, and cleaner images with less noise at higher ISO settings.

While the Olympus SH-3 impresses with its versatile zoom range, its tiny sensor imposes limitations. Images tend to exhibit lower dynamic range and detail resolution, especially noticeable in shadows and highlights. For instance, shooting landscapes with high contrast lighting revealed visible noise and reduced fine texture when pushed past ISO 400.

The Sony A390’s larger sensor and the absence of an anti-aliasing filter give it an edge in sharpness and tonal gradation. Details in foliage or fabric textures appeared more pronounced and natural. Additionally, the A390’s native ISO sensitivity ranges from 100-3200, producing cleaner results at higher ISOs compared to the Olympus’s 125-6400 range, which often resorts to heavy noise reduction at upper levels.

Viewing Your Shot: Screen and Viewfinder Differences

When framing and reviewing images, both cameras take different approaches. The Olympus SH-3 sports a fixed 3-inch touchscreen with 460K dots resolution, while the Sony A390 offers a smaller 2.7-inch tilt-capable LCD with just 230K dots. However, the Sony counters with its optical pentamirror viewfinder, covering 95% of the frame at 0.49x magnification, which the Olympus completely lacks.

This means in bright daylight or fast-moving street photography contexts, the Sony’s viewfinder is vastly superior for precise, stable composition without screen glare. The Olympus’s touchscreen interface offers responsive touch-to-focus and menu navigation but struggles in direct sunlight, making it less than ideal for extended outdoor shooting.

Overall, the Sony’s optical viewfinder provides a more traditional DSLR experience that many photographers highlight as indispensable for manual focusing, tracking subjects, or conserving battery life. Conversely, the Olympus embraces modern touchscreen convenience for casual shooting but sacrifices some precision and tactile feedback.

Auto Focus Systems: Speed, Accuracy, and Tracking

AF systems make or break candid moments, wildlife images, and dynamic sports shots.

The Olympus SH-3 uses a contrast-detect autofocus system with face detection and multi-area focusing options. It boasts a continuous shooting speed of 11.5 fps, which is commendable for a compact. However, in low light or complex tracking scenarios such as birds in flight, its AF occasionally gets lost or hunts aggressively.

The Sony A390 employs a 9-point phase-detection AF system supplemented with contrast detection during live view. Although its continuous shooting speed caps at a modest 3 fps, the phase detect AF provides faster and more reliable subject acquisition and smoother tracking in action sequences.

From extensive AF testing - I conducted shooting sessions capturing fast-moving cyclists and wildlife - the Sony’s AF system exhibited better responsiveness and locking capability under variable lighting compared to the Olympus, which sometimes lagged or centered focus awkwardly on unintended areas.

Face detection on both cameras is practical for portraits. The Olympus, however, does not offer eye-detection autofocus, which is increasingly critical for sharp portraiture. Sony’s A390 also lacks eye-AF but its overall AF accuracy on faces was marginally better given the DSLR system.

Lens Flexibility and Macro Performance

One of the prime advantages of the Sony A390 is its compatibility with the extensive Sony/Minolta Alpha lens mount. From speedy primes to professional telephotos, you have access to over 140 lens models, enabling you to tailor your optics perfectly to your genre - be it portraits, macro, or wildlife.

The Olympus SH-3’s 24x optical zoom 25-600mm (equivalent) fixed lens offers enormous versatility but cannot be swapped. This trade-off benefits portability but limits creative lens choices.

For macro lovers, the Olympus’s minimum focusing distance of 3 cm allows intriguing closeups, supported by sensor-shift image stabilization to help reduce blur. The Sony relies on lens choice for macro (with no built-in stabilization in-body), depending on compatible optics for close focusing capabilities.

If macro and creative lens experimentation are important, Sony’s A390 wins hands down. But for users desiring an all-in-one approach without changing gear, Olympus provides a compact, competent alternative.

Durability, Weather Protection, and Battery Life

For demanding outdoor use, durability and endurance matter.

Neither the Olympus SH-3 nor the Sony A390 offer weather sealing or ruggedized bodies, which limits use in harsh environments. The Olympus’s compact design means less bulk but also less protection and fewer manual controls to operate with gloves.

Battery life leans heavily in favor of the Olympus here - rated for approximately 380 shots per charge vs Sony’s 230 shots. This matters for travel, day hikes, or casual outings where charging opportunities are limited.

Overall, the Olympus’s smaller footprint enables better portability and longer endurance for casual use. The Sony’s DSLR heft suggests robustness but requires more frequent recharging during intensive shooting.

Image Stabilization and Low-Light Handling

The Olympus SH-3 boasts sensor-shift image stabilization incorporated into the body, effective for handheld shots across the long zoom range. This is a valuable feature given the relatively slow maximum aperture (F3.0-6.9) and necessity to avoid motion blur at telephoto distances.

The Sony A390 has “sensor-based” stabilization indicated, but this is misleading because stabilization mainly comes from lenses with Optical SteadyShot rather than the camera body itself.

In low-light testing across indoor events and street scenes at night, the Olympus’s stabilization combined with ISO 6400 capability allows usable handheld shots, albeit with noticeable noise and softness beyond ISO 800. The Sony’s APS-C sensor inherently produces cleaner images at ISO 1600 and below, but its lack of internal IS requires support lenses or tripods for stabilization-critical scenarios.

Video Capabilities: The Olympus Leaps Forward

If video is on your radar, the Olympus outshines the Sony A390, which does not support video recording at all. The Olympus SH-3 offers 4K UHD at a modest 15 fps and Full HD 1080p at 60 fps for smooth motion capture, alongside time-lapse recording functions.

No microphone or headphone jacks exist on the Olympus - a limitation for professional audio work - but for casual video, its integrated stabilization and zoom provide enough flexibility.

The Sony A390 is strictly a stills camera, so video enthusiasts won’t find it suitable.

Real-World Photography Tests: Sample Shots and Image Quality Review

To put theory into practice, I took both cameras on a varied shooting trip encompassing landscapes, portraits, street, and wildlife scenes.
