Olympus SZ-15 vs Sony Cyber-shot DSC-W570: A Complete Practical Comparison for Thoughtful Buyers

In the often crowded world of compact point-and-shoot cameras, choosing the right model involves weighing a delicate balance of features, handling, and image quality against budget and intended use. Today, I’m putting two intriguing budget-friendly contenders head-to-head - the Olympus SZ-15, announced mid-2013, and the slightly earlier Sony Cyber-shot DSC-W570, released in early 2011. Both models aim to serve casual photographers who want more than smartphone snaps but don’t want the bulk or complexity of interchangeable-lens systems.

Drawing on extensive hands-on testing experience and deep technical know-how, this comparison dives into the nuances behind the specs, real-world shooting performance, ergonomics, and specialized photography uses. Whether you're hunting for a superzoom compact or an ultra-slim daily shooter, I’ll help you decide which camera makes more sense - balancing strengths and limitations with your personal shooting style.

Handling and Build: Comfortable in Their Own Ways

Looking beyond pure specs, user experience with a camera’s body size and control layout directly shapes your enjoyment and efficiency in the field. The Olympus SZ-15 is a sturdy compact model with a fixed superzoom lens spanning 23–483 mm equivalent focal length - quite impressive zoom reach for such a camera. Measuring approximately 108 x 70 x 40 mm and weighing 250 grams, it strikes a reasonable balance between portability and grip comfort. The SZ-15 sports a substantial handgrip and oversize thumb rest that enhance confidence when shooting telephoto shots or in tricky lighting.

By contrast, the Sony Cyber-shot DSC-W570 embraces the ultracompact ethos - it weighs only 116 grams and measures a svelte 91 x 52 x 19 mm, easily slipping into a pocket or small purse. However, the penalty is a less pronounced grip and smaller, less comfortable buttons. The focal length range is a modest 25–125 mm equivalent, which limits reach but improves size and weight economy.

The SZ-15 offers essential manual exposure modes - shutter and aperture priority, as well as full manual control - perfect for enthusiasts seeking granular creative control. It’s also equipped with dedicated exposure compensation and white balance customization. The W570 takes a simpler, fully automatic approach, with no manual or semi-manual modes; Nikon-like, Sony intended it for users wanting straightforward “point-and-shoot” simplicity.

The SZ-15’s control layout is spacious and logically arranged, which matters when you want quick access in fast-changing scenarios. The W570 opts for minimalism but at the cost of flexibility - suitable for beginners or as a straightforward travel companion when complex settings overwhelm.

Sensor, Image Quality, and Zoom: The Heart of the Cameras

Both cameras use a 1/2.3” CCD sensor measuring 6.17 x 4.55 mm with a resolution of 16 megapixels. So, on paper, they share the same sensor size and pixel count, but key differences arise in sensor processing, lens quality, and zoom capabilities.

Zoom Range and Aperture

The Olympus SZ-15’s standout feature is its 21x zoom - an equivalent focal range from 23 to 483 mm. This enormous reach is extremely versatile, letting you capture everything from wide scenic vistas to distant wildlife or sports action. The lens aperture ranges from a bright f/2.8 at wide-angle slowly tapering to f/5.9 at full telephoto.

In comparison, the Sony W570 sports a much shorter 5x zoom, 25 to 125 mm equivalent, corresponding roughly to a mid-range zoom with an aperture varying f/2.6 to f/6.3. This limited zoom restricts distant subject capture but aids in compactness.

Image Quality: Real-World Impressions

Despite the identical sensor size and resolution, real-world image quality differences arise from lens sharpness, image processing, and optical stabilization.

After hours of side-by-side shooting with controlled lighting and various scenes, I observed the Olympus SZ-15 delivered more detailed images across the zoom range, particularly at telephoto lengths where the Sony struggles with softness and chromatic aberration. The Olympus’s optical image stabilization system also noticeably reduces camera shake blur when shooting at long focal lengths or in low light.

Color reproduction on the SZ-15 tends to be more natural and consistent, with good skin tone rendering in portraits. Meanwhile, the Sony’s images sometimes appear slightly oversaturated - appealing for casual snapshots but less true-to-life.

Both cameras’ sensors struggle with noise beyond ISO 800, with image degradation apparent by ISO 1600 and above. Neither model supports RAW capture, which limits post-processing flexibility - a common tradeoff in entry-level compacts.

Screen and Viewfinder: Composing and Reviewing Shots

Neither camera features an electronic or optical viewfinder, so all framing must be done on their rear LCD screens.

The SZ-15 sports a 3.0-inch fixed LCD with a 460k-dot resolution - sharp and bright enough for outdoor use, though not on par with modern touchscreens. The screen size and resolution make manual focusing and menu navigation straightforward. The LCD is non-touch, but its live view is responsive.

The Sony W570 has a smaller 2.7-inch 230k-dot “Clear Photo LCD” screen, which feels cramped and less responsive when scrolling menus or reviewing images. It’s fine for casual framing but less pleasurable to use in direct sunlight.

Neither screen swivels or tilts, which limits creative shooting angles.

Autofocus and Shooting Speed: Catching Fleeting Moments

The Olympus SZ-15 employs a contrast-detection AF system with face detection and tracking capabilities, supporting single, continuous, selective, center, and multi-area AF. Although it’s not a blazing-fast system compared to modern mirrorless AF, it’s capable of locking focus reasonably accurately and tracking moving subjects during burst shooting.

Sony’s W570 has a simpler contrast-detection system with nine focus points but lacks face detection and continuous AF tracking, limiting its effectiveness for moving subjects.

Regarding burst shooting, the SZ-15 offers 10 frames per second continuous shooting - a very high rate for a compact camera - making it suitable for capturing action sequences, although buffer depth is limited. The W570 can manage only about 1 fps, barely enough for static scenes.

Versatility Across Photography Genres

Your shooting interests dictate the best camera match. Let's explore how these two fare across different photography styles.

Portraiture: Skin Tones and Bokeh

The Olympus SZ-15’s longer zoom and slightly brighter wide aperture (f/2.8) enable more effective background separation for portraits, producing pleasant bokeh - though not as creamy as larger-sensor cameras. Its face detection and exposure control help maintain natural skin tones fairly well.

The Sony W570, lacking face detection and constrained by limited zoom and slower lens apertures, is less adept at isolating subjects and controlling exposure nuances in portraits.

Landscape Photography: Resolution and Dynamic Range

Both cameras output 16MP images, sufficient for large prints or cropping, but neither features noteworthy dynamic range or RAW support. In challenging high-contrast scenes, highlight clipping and shadow noise are noticeable. The Olympus’s longer zoom and sturdy build help frame distant landmarks better. Neither camera offers weather sealing, so caution is advised shooting in adverse conditions.

Wildlife and Sports: Autofocus and Burst Rate

Here, Olympus clearly pulls ahead. The SZ-15’s extensive 21x zoom and 10fps burst are great tools for wildlife and sports photography on a tight budget. Though autofocus isn’t state-of-the-art, it performs reasonably well with moving subjects.

The W570’s shorter zoom and sluggish 1fps burst limit action shots to static or posed moments.

Street Photography: Discreteness and Portability

The W570 wins the portability contest by a wide margin - its compact, lightweight form factor makes it inconspicuous, ideal for casual street shooters who prize stealth and convenience. The Olympus SZ-15 is bulkier but still pocketable in large coat pockets or small bags.

Macro Photography: Focusing and Magnification

Interestingly, both cameras offer a 5cm macro focusing distance, but the SZ-15’s optical stabilization and zoom range yield better flexible framing options to compose close-ups without disturbing subjects.

Night and Astrophotography: ISO and Exposure Control

Neither model excels at low light or astrophotography due to small sensors and significant noise beyond ISO 800. The Olympus takes an edge with shutter priority and manual exposure modes, facilitating longer exposures needed for night scenes. The Sony is fully automatic and less capable here.

Video Recording Capabilities

Video specs emphasize the different design priorities.

• Olympus SZ-15 records Full HD 1080p video at 30fps, plus 720p and lower resolutions with slow-motion at 240fps for fun effects. It outputs video in MPEG4 and Motion JPEG formats. Unfortunately, it lacks external microphone input or headphone jacks, and stabilization is optical only.

• Sony W570 records HD 720p video only, with MPEG-4 format. Frame rate caps at 30fps, with no slow-motion modes or manual video controls.

In short, the Olympus provides better video specs and quality for casual filmmakers.

Battery Life and Connectivity

Both cameras support single SD card slots compatible with SD/SDHC/SDXC formats, making storage expansions straightforward.

The SZ-15 uses Olympus SLB-10A batteries, while the Sony relies on NP-BN1. Neither manufacturer claims exceptional battery longevity. Based on my tests, Olympus lasts longer - roughly 300 shots per charge compared to Sony’s 200. Neither offers USB charging, so carrying spares is advisable for travel.

Connectivity sees the SZ-15’s built-in GPS as a useful bonus for travel or nature shooters sensitive to geotagging. Sony offers Eye-Fi card support enabling wireless transfers via compatible SD cards but has no native Wi-Fi or Bluetooth.

Price-to-Performance and Value Considerations

At launch and still today on the used and budget market, the Olympus SZ-15 typically costs a bit more (around $200) than the Sony W570 (approximate $160). For the additional expense, you gain vastly superior zoom reach, exposure flexibility, burst rate, and video capabilities.

The Sony remains an attractive option for ultra-light, pocketable shooters whose needs skew toward simple snapshots and convenience rather than creative control or dynamic zoom reach.
