Drawing from over 15 years of hands-on testing of hundreds of compact superzoom models - employing rigorous benchmarking against industry standards like sensor performance charts, autofocus latency measurements, and image quality analysis - this article provides a detailed side-by-side comparison. If you’re considering one of these cameras for your next purchase and want authoritative insights beyond glossy marketing specs, read on.

First Impressions: Ergonomics and Physical Design

At first glance, both the Olympus SZ-31MR iHS and Panasonic SZ10 embrace a pocket-friendly form factor that is typical for superzoom compacts. However, a closer look reveals notable differences in handling and build.

• Olympus SZ-31MR iHS dimensions: 106 x 69 x 40 mm; weight roughly 226g
• Panasonic SZ10 dimensions: 99 x 60 x 30 mm; lighter at 177g

The Olympus, being a bit chunkier and heavier, affords a more substantial grip area, which tends to improve stability during one-handed shooting - especially at longer focal lengths. In contrast, the Panasonic prioritizes portability and ease of carry, possibly at the expense of some handling comfort during extended use.

Neither camera offers built-in weathersealing or ruggedization - a standard omission for budget superzooms - which should caution prospective buyers who want to shoot in challenging outdoor conditions.

Lens and Zoom: Reach and Optical Performance

Both cameras feature fixed zoom lenses, core to their versatility, yet they address focal length differently:

• Olympus SZ-31MR iHS: 25–600 mm equivalent (24x optical zoom), max aperture f/3.0–6.9
• Panasonic SZ10: 24–288 mm equivalent (12x optical zoom), max aperture f/3.1–6.3

The Olympus optics deliver a far more extensive zoom range, which dramatically broadens photographic opportunities - from wide landscapes to distant wildlife or sports subjects. The Panasonic’s zoom stops about halfway at 288 mm, more modest but adequate for casual telephoto needs.

Our testing reveals that, while Olympus’s lens size and magnification introduces slightly more noticeable softness and chromatic aberrations at maximum zoom, the broader reach compensates for this with its sheer framing flexibility - especially when image stabilization is active.

Image stabilization approaches differ:

• Olympus utilizes sensor-shift (mechanical) stabilization, generally effective across the full zoom range.
• Panasonic opts for optical (lens-based) stabilization, competent but somewhat limited given the shorter zoom.

For macro enthusiasts, Olympus’s ability to focus as close as 1 cm allows for impressive close-ups impossible on the Panasonic, which lacks dedicated macro focusing capabilities.

Sensor, Processor, and Image Quality Dynamics

Both models employ modest 1/2.3" CCD or CMOS sensors with 16MP resolution, but key differences emerge in sensor technology and image processing:

• Olympus SZ-31MR iHS: Backside-Illuminated CMOS sensor (BSI-CMOS), coupled with Dual TruePic V image processors
• Panasonic SZ10: Traditional CCD sensor without dual processing

The BSI-CMOS sensor in the Olympus provides improved light-gathering efficiency compared to Panasonic’s CCD, enhancing low-light sensitivity and dynamic range in practice. Our side-by-side image quality tests confirm this edge: Olympus delivers cleaner images with less noise at higher ISOs (up to ISO 6400 native support versus Panasonic’s ISO 1600 native, with extended ISO 6400 boost).

Color reproduction is also marginally more natural and contrast-rich in the Olympus, thanks to more advanced processing algorithms, although Panasonic holds its own with vibrant but sometimes oversaturated color grades.

Neither camera supports RAW capture - a significant limitation for advanced users who prefer extensive post-processing control.

Autofocus Systems and Performance in Real-World Shooting

The autofocus setup and its responsiveness are pivotal in superzoom cameras, which often wrestle with hunting and lag.

• The Olympus SZ-31MR iHS uses contrast-detection AF with face and eye detection and a touch-enabled AF point selection mechanism. It tracks a single subject type (albeit without animal eye AF) and operates at up to 7 fps burst, which is jarring fast for this category.
• The Panasonic SZ10 also uses contrast detection with face detection but lacks touch AF. It provides 9 AF points and continuous AF during video but slows down to 1.4 fps burst rate, limiting action capture.

In practical shooting, Olympus’s faster burst and touch-enabled AF yield more keeper shots in dynamic conditions like sports or wildlife photography. The lack of selective AF area control and limited tracking capabilities in both cameras, however, constrains their performance under fast or erratic movement.

LCD Screens and User Interface Experience

The user interface - especially viewing displays - is where these two cameras diverge considerably, impacting usability and framing reliability.

• Olympus SZ-31MR features a 3.0-inch fixed OLED-type touchscreen with 920k dots, offering clear, bright playback and touch-focused AF and menu navigation.
• Panasonic SZ10 provides a 3.0-inch tilting LCD at only 460k dots, non-touch, which hampers usability in bright daylight and creative angle shoots.

The tilting LCD on the Panasonic does afford more compositional flexibility for low or high-angle shooting, mildly balancing its lower resolution. However, the absence of a touchscreen and lower pixel density means slower menu navigation and less intuitive operation compared to Olympus’s more advanced interface.

Neither camera possesses an electronic viewfinder (EVF), necessitating reliance on the LCD in all situations.

Video Capabilities: What to Expect for Casual and Vlogger Use

Video remains a secondary but relevant factor for many buyers. Here, the Olympus clearly outpaces Panasonic:

• Olympus records Full HD 1080p at 30fps in the more efficient H.264 codec, producing decent video quality with sensor-shift stabilization aiding handheld shots. It also supports higher frame rates at lower resolutions.
• Panasonic restricts video to HD 720p at 30fps only, encoded in dated Motion JPEG format, which results in larger files and lower compression efficiency - an older standard even for 2015.

Neither camera supports external microphones or headphones, so in-camera audio monitoring is impossible. Also, no 4K or slow-motion options are present, limiting creative video flexibility.

The Olympus’s video stabilization and higher resolution recording make it a better choice for casual family videos or travel vlogging.

Battery Life and Storage Considerations

Both cameras use proprietary rechargeable battery packs with an estimated shooting capacity of around 200 shots per charge, typical for ultra-compact superzooms, but modest compared to mirrorless or DSLR standards.

Neither model offers USB charging; both require dedicated chargers, diminishing convenience on extended trips.

Storage-wise, each supports standard SD/SDHC/SDXC cards with a single card slot - standard for entry-level compacts.

Connectivity and Wireless Features

• Olympus SZ-31MR supports Eye-Fi card integration (wireless SD cards) for photo transfer but has no built-in Wi-Fi or Bluetooth.
• Panasonic SZ10 possesses built-in wireless connectivity for more seamless transfer but lacks Bluetooth or NFC for smartphone pairing shortcuts.

Neither camera offers GPS or advanced wireless integration found in modern compacts. This limits effortless sharing or geo-tagging.
