Olympus SZ-15 vs. Sony Cyber-shot DSC-TX66: A Hands-On Comparison of Two Compact Cameras

Selecting the right compact camera in today’s crowded market can be daunting. Among numerous options, the Olympus SZ-15 and Sony TX66 emerged a decade ago, targeting photography enthusiasts seeking portability without sacrificing versatility. In this deep-dive comparison, I share fresh insights from extensive firsthand testing and technical analysis, aiming to help you find the best fit for your photography goals - whether you’re hunting landscapes, portraits, or travel memories.

Getting Acquainted: Design and Handling Insights

When choosing a compact, size and ergonomics are often deal-breakers, especially if portability matters to you. Here’s how these two stack up:

• Olympus SZ-15: This model embraces a traditional compact DSLR-like ergonomics but remains pocketable. Measuring 108×70×40 mm and weighing 250g, it feels chunky but comfortable in my hand, thanks to a pronounced grip. The physical heft reassures, especially during extended shooting sessions.

• Sony TX66: Ultracompact and streamlined, the TX66 is a minimalist charm at just 93×54×13 mm and 109g. It’s ultra-light and pocket-friendly, perfect for discrete street or travel photography. However, its slimness means smaller buttons and less grip security, which can affect one-handed control.

Moving to controls, the top view design highlights distinct philosophies:

• The SZ-15 provides a DSLR-like top plate with dedicated mode dials, shutter speed, and exposure compensation buttons, appealing to photographers who like manual control.

• The TX66 embraces touch-centric operation with minimal physical buttons, prioritizing sleekness over direct control.

Takeaway:
If you value tactile feedback and manual settings on the fly, the Olympus SZ-15's form factor suits you. If pocketability and lightweight carry trump manual control, the Sony TX66 wins.

Sensor Technology and Image Quality: Pixel Prowess Under the Hood

For any camera, sensor specifications and associated image quality are paramount. Both cameras share the same sensor size (1/2.3” measuring approximately 6.17x4.55mm), which technically limits their ability to capture light compared to larger sensors, but notable differences emerge:

• Olympus SZ-15 uses a 16MP CCD sensor with an optical low-pass filter (anti-aliasing filter). CCDs are older sensor tech, known for excellent color accuracy but more noise at high ISOs.

• Sony TX66 features an 18MP backside-illuminated CMOS sensor (BSI-CMOS), a significant technological leap that generally offers better performance in low light, faster readout, and higher native ISOs up to 12800.

In real-world testing, the TX66 produces images with better dynamic range and cleaner shadows under low-light conditions, thanks to its BSI-CMOS design. The Olympus, meanwhile, holds its own in bright daylight with pleasing color rendition but starts showing noise and softening above ISO 800.

Neither camera supports RAW capture, so image quality optimization relies entirely on JPEG processing - which leans in Sony’s favor due to its superior BIONZ image processor.

Resolution and Lens:
The TX66's slightly higher resolution (18MP vs. 16MP) produces marginally sharper images, particularly when pixel-peeping or cropping. Both cameras have an anti-aliasing filter, meaning very fine detail can be softened, but practical use rarely makes this a limitation.

Viewing and Interface Experience: Screen and Live View

In field photography, the screen quality and user interface matter:

• The SZ-15 sports a 3.0-inch LCD screen with 460k-dot resolution and fixed positioning. The display is clear but modest in resolution and not touch-sensitive, limiting intuitive menu navigation.

• The TX66 offers a slightly larger 3.3-inch OLED display with 1230k dots and touchscreen capability. I found the OLED brightness, contrast, and color rendition superior, especially in daylight. The touch interface improves focus point selection and menu control.

Neither has an optical or electronic viewfinder, which may hinder composition in bright sunlight.

Zoom Capabilities: Telephoto and Macro Performance

The lens range is a crucial differentiator, especially for travel, wildlife, and macro shooting:

• Olympus SZ-15 boasts a remarkable 21x optical zoom (23–483 mm equivalent), covering from wide-angle to significant telephoto reach. This versatility means you can tackle landscapes, wildlife, and distant subjects without switching lenses.

• Sony TX66 offers a 5x zoom (26–130 mm equivalent), more modest but sufficient for everyday snapshots and moderate telephoto needs.

In macro mode, the Sony focuses as close as 1cm at the wide end, excellent for detailed close-ups of flowers or textures. The Olympus reaches 5cm, still practical but less intimate.

Image stabilization is optical and present on both; however, Olympus’s lens-based stabilization is effective in suppressing handshake at the long end of the zoom, enabling sharper shots handheld.

Autofocus System and Shooting Performance

For capturing fleeting moments, autofocus and continuous shooting specs matter:

• Both cameras use contrast-detection autofocus with face detection but have no phase-detection.

• The Olympus provides single, continuous, and tracking AF modes and includes basic face detection but no advanced eye or animal detection.

• The Sony also supports face detection and contrast AF but lacks dedicated continuous AF modes and doesn’t offer manual focus options beyond simple peaking.

Both cameras support 10 fps burst shooting, but the buffer depth and sustained speed differ:

• Olympus handles short bursts well but slows down quickly due to buffer constraints.

• Sony’s continuous shooting at 10 fps is nominally similar but limited to fewer frames before buffering.

In practice, for sporadic action like kid’s sports or street photography, both cameras can catch decisive moments but are not ideal for heavy sports or wildlife tracking.

Versatility Across Photography Genres

Portrait Photography

The Olympus’s longer zoom and faster aperture at the wide end (f/2.8) help generate softer bokeh in portraits, but the small sensor limits background blur potential. Face detection autofocus helps maintain sharp eyes, but there is no eye-tracking AF available.

The Sony, with a smaller zoom and slightly slower aperture (f/3.5), yields less subject-background separation, but the sharper OLED screen aids precise focusing and review.

Landscape Photography

Landscape photography benefits from sensor dynamic range, resolution, and weather resistance.

• Neither camera provides weather sealing or rugged build, so use caution outdoors.

• Olympus has a broader zoom range, from moderate wide angle to super-telephoto.

• Sony’s higher ISO ceiling and superior dynamic range provide more latitude in shadow recovery.

Neither supports RAW, limiting post-processing latitude, but for casual landscapes JPG output is acceptable.

Wildlife Photography

Olympus’s 21x zoom offers a definite edge for wildlife enthusiasts on a budget seeking longer reach without the bulk of interchangeable lenses or teleconverters.

However, autofocus speed is moderate, and tracking is not optimized for erratic animal movement. Sony’s shorter zoom makes it less suitable for distant subjects.

Sports Photography

Neither camera holds an advantage for serious sports photographers:

• Autofocus systems here are basic with limited tracking.

• Both lack mechanical shutters capable of very fast shutter speeds typical in high-end sports cameras.

• Burst rate is sufficient for casual sports photography but would falter in fast-paced action.

Street Photography

Sony’s compactness, light poundage, and subdued styling cater perfectly to street photographers who prefer to blend in.

The Olympus’s bulk and zoom length make it more conspicuous and less convenient for quick candid shots.

Additionally, Sony’s touchscreen interface enables flexible focus selection on the fly, useful for spontaneous street scenes.

Macro Photography

Sony takes the crown here with 1cm super close-focus capability, enabling sharp, detailed close-ups.

The Olympus’s macro at 5cm is less intimate but still functional for flowers, small objects, and textures.

Night and Astrophotography

Low-light performance reflects sensor tech:

• Sony’s BSI-CMOS sensor and ISO range up to 12800 grant more flexibility.

• Olympus maxes at ISO 3200, and its aging CCD elevates noise levels at higher ISOs.

Neither offers manual bulb modes, limiting long-exposure astrophotography options.

Video Capabilities

Both cameras can record Full HD 1080p video:

• Olympus: 30fps max, AVI MPEG4, Motion JPEG

• Sony: 60fps max at 1080p, MPEG-4 and AVCHD formats

Sony’s higher frame rate facilitates smoother video and better slow-motion conversion.

Neither supports microphone input or headphone monitoring, so audio quality depends on built-in microphones.

Optical image stabilization aids handheld video in both, but Sony’s sensor stabilization and newer processor yield steadier footage.

Travel Photography

For travel, consider versatility, size, and battery life:

• Sony excels in compactness, weight (109g), and screen usability but offers only 5x zoom.

• Olympus offers a versatile 21x zoom but at twice the weight and bulk.

• Battery life: Sony rated at 250 shots (NP-BN battery), whereas Olympus battery life is unspecified but likely around 300 shots.

Storage: Olympus supports SD cards; Sony also supports Memory Stick Duo and microSD cards.

Professional Use and Workflow

Neither the Olympus SZ-15 nor Sony TX66 caters directly to professionals:

• No RAW support limits post-processing flexibility.

• Limited manual exposure modes on the Sony restrict creative control (no shutter or aperture priority).

• Olympus offers shutter, aperture priority, and manual exposure, providing enthusiasts with creative options.

• Workflow integration is basic, with USB 2.0 wired transfer and no wireless on the Sony, but Olympus includes built-in Wi-Fi and GPS tagging - useful for travel documentation.

Build Quality and Weather Resistance

Neither camera features weather sealing, dustproofing, or robust body construction. Both are typical compact designs reliant on careful handling, not suitable for extreme environments.

Price and Value Assessment

At launch, the Olympus SZ-15 was priced around $200, while the Sony TX66 retailed near $350. Despite being older models, they provide different value propositions today:

• Olympus SZ-15: Best value for users prioritizing zoom reach and manual control for diverse shooting.
