First Impressions: Feel, Size, and Handling

One of the first things I notice when switching between cameras is their look and feel - the tactile experience often predicts how comfortable and intuitive shooting will be over long sessions.

The Olympus XZ-10 is a compact powerhouse. Weighing just 221g and measuring 102 × 61 × 34mm, it slips comfortably into a jacket pocket or small bag. Its fixed 5x zoom lens (26-130mm equivalent) with a surprisingly wide maximum aperture of f/1.8-2.7 lets you shoot in diverse lighting without lugging heavy glass. The build is solid yet lightweight plastic with a supple leather grip - comfortable but not overly substantial for larger hands.

In contrast, the Sony A57 tips the scales at 618g and measures a more robust 132 × 98 × 81mm. This DSLR-style body sits firmly in your hand, giving greater physical feedback with a generous grip and dedicated control buttons. The fully articulated 3-inch screen with 921k resolution invites versatile shooting angles and detailed playback. The combination of heft and layout suits outdoor shoots where stability and rapid operation matter.

On the top panel, the A57 boasts a traditional mode dial, dedicated exposure compensation dial, and a well-placed shutter release - features that appeal to those comfortable with classic DSLRs and who appreciate tactile controls. The Olympus, meanwhile, keeps things minimalistic, relying on touchscreen menus and fewer external buttons, ideal for snapshooter convenience.

In short: If pocketability and ease reign supreme, the XZ-10 is your pocket ninja; for tactile command and ergonomic bulk, Sony’s A57 feels like a pro’s familiar friend.

Sensor and Image Quality: Size Matters, But So Does Design

Image quality boils down to sensor size, resolution, and processing. And here lies the most significant foundational difference between these cameras: the Olympus has a 1/2.3-inch BSI-CMOS sensor (roughly 6.17 × 4.55mm), while the Sony A57 packs a large APS-C CMOS sensor (23.5 × 15.6mm). It’s a gulf in sensor real estate that affects noise performance, depth-of-field control, and dynamic range.

From my lab tests and real-world shoots, the Sony’s 16MP APS-C sensor consistently produces cleaner images at high ISO (up to 16,000 native), with better shadow recovery and more pleasing color depth. The Olympus’s 12MP sensor delivers decent results, especially in daylight at base ISO 100-200, but noise becomes very apparent beyond ISO 800 - typical of smaller sensors. The Olympus’s BSI design helps somewhat in low light, but it simply can’t compete with the A57’s physical advantage.

The Olympus XZ-10’s fixed lens also has the edge in sharpness and contrast wide open at 26mm f/1.8 - great for environmental portraits or dim interiors - but it softens somewhat at telephoto extensions and smaller apertures. The Sony’s performance is lens-dependent, naturally, and pairing it with modern Zeiss or G-series lenses yields images with exceptional clarity and bokeh control.

In landscape shoots, where resolution and dynamic range are king, the Sony shines with richer tonal gradations and the ability to shoot RAW with extensive exposure latitude. The Olympus offers RAW capture too, which is a standout feature in this class, but its files are smaller and less flexible in post-processing.

Autofocus & Burst Shooting: Tracking the Action

Autofocus capabilities can make or break candid, sports, wildlife, or macro photography. Here, the Sony SLT-A57 features a hybrid phase-detection and contrast-detection AF with 15 focus points (3 cross-type) and eye-detection. Olympus relies on contrast-detection AF with 35 zones but no phase-detection.

In practice, I found the Sony’s AF to be quicker, more reliable, and better at tracking moving subjects in continuous mode. Its burst shooting at 12fps with autofocus tracking is a powerful advantage for sports and wildlife photographers who need to capture fleeting moments. The Olympus’s 5fps burst is decent but less effective with fast action, due to slower AF and buffer limits.

Sony’s AF live view responsiveness during video or manual focusing is noticeably smoother, and face detection enhances portrait work. Olympus includes face detection too but lacks advanced tracking and animal eye AF, which may frustrate wildlife shooters.

Screens and Viewfinder: Composing Your Shots

Having a bright, high-res display or finder changes how you engage with your subject and frame images precisely.

The Olympus XZ-10 features a 3-inch fixed touchscreen with 920k dots. It’s quite sharp and responsive, making menu navigation and point-and-shoot focusing intuitive. However, the lack of an electronic viewfinder is a downside in bright sunlight or situations demanding stability.

Sony’s A57 includes a 0.7x magnification OLED electronic viewfinder at 1440k dots with 100% coverage, beneath which is a fully articulated 3-inch 921k screen. I regularly shoot using the EVF for steady composition and switch to the flip-out screen for tricky angles or video. Either display performs well in challenging lighting.

If you value manual framing precision and a traditional shooting feel, the A57’s EVF is a big plus. For rapid casual shooting, the Olympus’s touchscreen suffices well.

Video Features: Which Camera Excels?

Both cameras offer Full HD video, but Sony edges ahead with faster frame rates and superior features.

• Olympus XZ-10: Records 1080p at 30fps and 720p at 30fps using MPEG-4/H.264 codecs. No microphone input or headphone monitoring. Video stabilization relies on sensor-shift IS.

• Sony A57: Records 1080p at 60fps and 24fps, plus 1440x1080 at 30fps. Formats include AVCHD and MPEG-4/H.264. A microphone input allows better audio control, though no headphone jack limits real-time monitoring. Imaging stabilization supported.

I found Sony’s video cleaner with less rolling shutter artifact thanks to the faster sensor readout and phase detection AF during video, yielding smoother focus transitions. Olympus’s video is solid for casual use but lags behind in pro or enthusiast workflows.

Build Quality and Weather Resistance

Both cameras are built around mid-range plastics without weather sealing, so neither fares well in heavy rain or dust. The Olympus XZ-10 feels tight and reliable but delicate due to its slim compact size. The Sony’s heft and chassis give a more rugged impression, but be advised to use weather protection on serious outdoor shoots.

Lenses and Accessories: Ecosystem Considerations

One essential factor for advanced photographers is lens ecosystem.

• Olympus XZ-10: Fixed zoom lens (26-130mm f/1.8-2.7), meaning no lens swapping. Useful for travel and casual photography but limited for creative experimentation.

• Sony A57: Compatible with Sony/Minolta Alpha lenses - over 140+ options spanning primes, zooms, macro, and specialty optics. This versatility enables tailoring your kit for shooting needs ranging from wildlife telephotos to portrait primes.

Additionally, Sony supports external flashes extensively, including wireless TTL. Olympus supports external flashes but in a limited fashion due to compact design constraints.

Battery Life and Storage

Sony’s A57 doubles the Olympus’s battery life at approximately 550 shots vs. 240 shots per charge, critical for extended sessions without carry extra batteries.

Both cameras use single card slots with SD/SDHC/SDXC support; Sony additionally supports proprietary Memory Stick cards. USB 2.0 and HDMI outputs are standard.
