Olympus Stylus 1s vs Sony SLT-A58: A Hands-On Quest for the Best Versatile Shooter

When stepping into the camera market - a crowded arena spanning pocketable superzooms to full-frame beasts - it's imperative to drill down beyond specs and marketing fluff. Having spent well over a decade dissecting cameras in studio and field conditions, I’m often faced with comparisons between very different camera types. Here you'll find an honest, experience-driven appraisal comparing two distinct yet intriguing models that sit at crossroads of design philosophy and user intent: the Olympus Stylus 1s, a fixed-lens small-sensor superzoom bridge camera, and the Sony SLT-A58, a traditional APS-C sensor DSLR-style with an interchangeable lens mount.

The Olympus 1s and Sony A58 cater to somewhat overlapping but ultimately different users - so let's unpack their real-world strengths, weaknesses, and who they ultimately serve best.

Size, Build, and Ergonomics: Handling in Your Hands Matters

First impressions matter, and no feature makes a difference so quickly as a camera’s ergonomics. The Olympus Stylus 1s comes in a compact, almost pocketable bridge form factor with SLR-like styling, measuring 116 x 87 x 57 mm and tipping the scales at a sprightly 402 grams. It’s light enough for long walks and street adventures but feels solid with a thoughtfully textured grip.

The Sony A58, by contrast, is a compact DSLR-style camera, larger and heavier at 129 x 95 x 78 mm, weighing 492 grams. This bulk does translate into more substantial handholding comfort, particularly with larger lenses, and a reassuring robustness. But the extra heft demands a larger bag and can tire your wrist - especially during extended handheld shooting.

Looking at the top-down layout…

…the Olympus employs easily accessible buttons and a decent mode dial configuration, optimized for quick zoom and aperture control via its fixed lens. Meanwhile, the Sony’s DSLR-inspired control scheme provides dedicated dials for exposure compensation, modes, and a more extensive array of buttons, appealing to experienced users craving tactile feedback and quick manual control.

Tilting screens grace both cameras, but...

…Olympus advances with a sharper 3-inch 1040k-dot touchscreen that's highly responsive and versatile for Live View composition. Sony’s 2.7-inch screen offers only 460k dots, no touchscreen control, and feels dated when reviewing images outdoors.

Ultimately, if portability and quick, efficient controls in a compact package speak to you, Olympus has the edge. For tactile DSLR enthusiasts wanting a classic layout, the Sony feels more familiar and customizable.

Sensor Technology and Image Quality: Small Sensor Versus APS-C

This is where the divide between the two widens considerably. The Olympus Stylus 1s houses a 1/1.7-inch BSI-CMOS sensor, 12 megapixels, measuring just 7.44x5.58 mm. Though advanced for its size - including backside illumination to boost light gathering - the small sensor hits physical limits in noise handling and dynamic range.

The Sony SLT-A58 sports a much larger APS-C CMOS sensor (23.2 x 15.4 mm), 20 megapixels, common in mid-range DSLRs. This sensor's 348 mm² surface area dwarfs Olympus’s 41.5 mm², capturing significantly more light and detail.

This difference profoundly impacts key aspects:

• Dynamic range: Sony achieves approximately double the dynamic range. Shadows retain detail better; highlights suffer less clipping.
• ISO performance: Sony outshines Olympus easily in low-light thanks to a higher maximum native ISO (16000 vs. 12800) and cleaner noise characteristics.
• Resolution: While Olympus’s 12MP is sufficient for everyday prints and web use, Sony’s 20MP images deliver greater cropping flexibility and larger prints without loss of sharpness.

In practice, I ran side-by-side tests in landscape and portrait scenarios. Sony’s files retain nuance in difficult light, such as wooded areas or backlit portraits, delivering punchy yet natural skin tones.

Olympus’s sensor pushed hard in dim situations revealed luminance noise and lesser shadow nuance - expected given the small sensor format. However, the fixed lens’s bright constant f/2.8 aperture managed decent depth of field separation and creamy bokeh in close-ups, surprising for a superzoom.

Autofocus and Performance: Tracking the Action

Autofocus defines usability for many users, especially in dynamic genres like wildlife or sports.

The Olympus 1s employs a contrast-detection AF system with 35 focus points and face detection, leveraging its touchscreen for AF point selection. Contrast-based AF, while accurate, is slower and prone to hunting under low light or fast subjects.

Sony’s SLT-A58 features a phase-detection AF system with 15 focus points (3 cross-type), eye detection, and continuous tracking. Phase-detection provides faster lock-on and smoother tracking for moving subjects compared to contrast systems.

Burst speed is close - Sony edges out with 8 frames per second continuous shooting, Olympus runs to 7 fps. But Sony’s autofocus keeps pace better over that sequence, especially with telephoto lenses, asserting itself as a better sports and wildlife tool.

Lens Ecosystem and Optics: Zoom Versatility vs Interchangeability

The Olympus Stylus 1s includes a fixed 28–300 mm f/2.8 equivalent zoom lens - a constant bright aperture across the entire tele range is impressive in this class. It’s versatile for landscapes, portraits, street photography, or even casual wildlife. The macro capability at 5 cm focusing brings additional versatility.

Sony offers a Sony/Minolta Alpha mount with access to a large variety of lenses: 143 lenses available across third parties and Sony's lineup. This includes primes, macro lenses, telephoto zooms, and specialty optics. Consequently, you’re less restricted by the A58’s body, able to build a system tailored to your needs - a significant advantage for professionals and enthusiasts alike.

Real-World Photography Disciplines: Strengths and Weaknesses

Let’s break down how each camera handles major photographic applications based on hours testing and field shootings.

Portraiture

• Olympus 1s: The fast constant f/2.8 lens produces pleasing background blur for subject isolation. Face detection AF works reliably for casual portraits. Skin tones are natural but slightly less refined due to smaller sensor tones and noise handling limitations.
• Sony A58: Larger sensor creates shallower depth of field with wide-aperture primes, superior skin tone reproduction from 20MP files, and more nuanced background separation. Accurate face detection combined with phase-detect AF improves sharpness on eyes, enterprise standard.

Landscape

• Olympus: Limited dynamic range and smaller sensor detail are handicaps. The long zoom enables dramatically framed vistas. However, shadows and highlight details drop off quickly in challenging light.
• Sony: Stunning dynamic range delivers excellent shadow recovery and highlight retention; 20MP resolution captures fine detail in landscapes, trees, and rocks impressively. Better suited to professional landscape workflows.

Wildlife Photography

• Olympus 1s: Zoom lens offers decent reach, but autofocus struggles to keep pace with fast animals. Burst speed lags behind DSLR competitors.
• Sony A58: Phase-detection AF excels tracking fast-moving wildlife, combined with 8fps burst to capture fleeting moments. Lens choice can extend telephoto reach substantially.

Sports Photography

Sony firmly leads here. Continuous tracking AF and faster burst capture rapid action with confidence. Olympus is not tailored to sports - while its 7fps is respectable, AF lag and smaller sensor hinder low-light gym or stadium shots.

Street Photography

• Olympus 1s: Compact size and quiet electronic viewfinder help with discreet shooting. Constant f/2.8 aperture great for variable light.
• Sony A58: Bulkier, louder shutter. LCD less usable outdoors. Yet advantageously flexible with prime lenses for wide or tight street scenes.
