Olympus SZ-10 vs Sony HX20V

Choosing Between the Olympus SZ-10 and Sony HX20V: A Hands-On Superzoom Showdown

In my years of thoroughly testing and comparing compact cameras, small-sensor superzooms have fascinated me for their blend of portability and versatile reach. Today, I’m diving into a detailed comparison of two contenders from the early 2010s: the Olympus SZ-10 and the Sony HX20V. Both fall into the compact superzoom category, promising impressive focal lengths wrapped in pocket-friendly bodies. However, as I’ve witnessed from thousands of hours behind the lens, the story is always richer than specs alone. Let me share my experience with these two, highlighting real-world performance across photography genres, technical nuances, and usability.

Getting a Feel: Size, Build, and Handling

When I first held these cameras side by side, their physical design differences instantly stood out. The Olympus SZ-10 has a slightly smaller footprint with dimensions of 106 x 67 x 38 mm and weighs 215 grams, whereas the Sony HX20V measures 107 x 62 x 35 mm but carries a tad more heft at 254 grams.

The slight bulkier feel of the Sony HX20V translates to a more reassuring grip in hand, particularly useful when shooting at extended telephoto lengths. Olympus’s SZ-10, while more compact, tends to feel a little less stable for my style of shooting, requiring careful hand positioning or a support. The textured body of the Sony offers better tactile feedback, and its control layout is designed to keep frequently used buttons within easy thumb reach, giving it a subtle edge in operability during fast-paced shooting.

This difference continues in the top control architecture.

Sony integrates a dedicated exposure compensation dial and a manual focus ring on the lens barrel - a feature missing on the Olympus. This allows the HX20V to appeal more to enthusiasts who want creative control. On the other hand, Olympus’s design focuses on simplicity, limiting manual controls, which might benefit beginners but frustrate those looking for versatility.

Sensor Technology and Image Quality Insights

Both cameras feature the familiar 1/2.3” sensor size commonly found in this class - a small sensor that sets inherent limits on image quality but enables compact superzoom lenses. Interestingly, the Olympus SZ-10 employs a 14-megapixel CCD sensor, whereas the Sony HX20V sports an 18-megapixel BSI-CMOS sensor.

This difference matters. My lab testing and field shooting with both cameras reveal that the Sony’s BSI-CMOS sensor provides better low-light performance and cleaner images at higher ISOs, owing to back-illuminated architecture that increases light-gathering efficiency. The Olympus’s CCD sensor, while capable of rendering pleasing colors under good light, struggles more with noise beyond ISO 400, as CCDs generally do.

Resolution-wise, Sony’s 18MP output feels sharper and more detailed in large prints or high-res pixel peeping, with maximum images sized at 4896 x 3672 pixels compared to Olympus’s 4288 x 3216. Still, I found Olympus’s files sufficient for web sharing and moderate 8x10 prints.

Color rendering is another story. The Olympus has a slightly warmer, more contrasty color signature, which some may find visually pleasing for portraits, while Sony’s images lean toward a more neutral and balanced palette good for landscapes.

Autofocus, Stabilization, and Shooting Speed

For action photographers like me, autofocus performance is a make-or-break feature.

The Olympus SZ-10 employs contrast-detection autofocus with face detection but lacks manual focus and aperture priority modes. Its continuous shooting speed is limited to 1 frame per second - quite slow for capturing decisive moments. By contrast, Sony’s HX20V features a 9-point contrast-detection AF system with face detection and selective AF area options. Manual focus is available too, giving the photographer more agency over focus precision.

Performance-wise, the Sony is noticeably faster and more accurate in locking focus, especially in daylight and somewhat challenging light. The Olympus often hunts or locks onto incorrect subjects, which can be frustrating when shooting wildlife or street scenes.

Continuous burst mode is where the Sony shines: up to 10 frames per second at full resolution, although it lacks autofocus tracking during bursts. The Olympus’s 1 fps makes it very limited for sports or wildlife action.

On the stabilization front, both cameras include image stabilization: Olympus employs sensor-shift stabilization, while Sony has optical stabilization built into the lens assembly. In handheld testing, both systems reduce blur effectively at moderate zoom lengths, but Sony’s optical image stabilization gives a slight edge when zoomed in at the telephoto end. In practice, I found steady shots easier with the HX20V, particularly in low light or at full zoom.

Viewing and User Interface

The rear LCD screen is critical in such compact cameras that lack viewfinders.

Olympus’s fixed 3-inch TFT LCD panel sports 460k-dot resolution, which feels insufficiently detailed and a little dim under bright sunlight. In contrast, Sony’s HX20V boasts a 3-inch XtraFine TruBlack LCD with 922k dots, delivering crisp, vibrant previews even outdoors. For me, this difference greatly impacts composition ease and focus accuracy on the fly.

Neither camera includes an electronic viewfinder, a drawback if you’re shooting in bright environments or prefer eye-level framing.

The user interface on Olympus is straightforward with clearly labeled mode dials but lacks customization. Sony’s menu system is more comprehensive, providing exposure compensation and white balance brackets, manual exposure modes, and more flexibility, enhancing creative control for enthusiasts.

Lens and Zoom Capability: Reach and Image Quality

Arguably, the main attraction to these cameras is their superzoom capability.

Olympus’s 18x zoom ranges from 28 mm to 504 mm equivalent focal length with an aperture of f/3.1-4.4 - the starting number is noticeably wide for a superzoom compact and good for landscapes and group shots. Sony HX20V offers a focal range of 25 mm to 500 mm with an aperture of f/3.2-5.8. The slightly wider short end on the Sony benefits indoor or travel shooters needing expansive framing.

Both lenses have a macro focus range down to 1 cm, enabling close-up photography, but the Olympus’s slightly faster aperture at the tele-end offers a tad more light for subject isolation and lower shutter speeds.

Sharpness across the zoom range in real-world shooting varies: Olympus tends to soften near the long end, especially when combined with digital zoom extension modes, whereas Sony maintains a bit more edge-to-edge sharpness throughout. Chromatic aberrations and distortion are moderately controlled on both lenses - within expectations for this class.

Real-World Photography Performance by Genre

To make sense of how these specs translate into actual shooting, I tested both cameras across typical photography genres.

Portraits

In portrait work, natural skin tone rendition, bokeh quality, and eye detection autofocus are crucial.

Both cameras utilize face detection autofocus, but Sony’s selective AF area and manual focus options made nailing sharp eyes easier. Olympus’s bokeh quality is less smooth, partly due to its sensor and lens design with a more abrupt background blur. Sony’s longer zoom and generally quieter focusing allowed more candid and intimate captures without drawing subject attention.

Landscapes

For landscapes, dynamic range and resolution are king.

The smaller CCD sensor on Olympus showed limited dynamic range, with blown-out highlights in harsh daylight, while Sony’s BSI-CMOS better preserved detail in sky and shadow areas. I also appreciated Sony’s higher resolution for producing larger, more detailed prints. Neither camera offers weather sealing, limiting outdoor use in adverse conditions.

Wildlife Photography

Shooting wildlife demands fast autofocus, telephoto reach, and burst shooting.

Sony’s 10 fps burst and faster AF combine to capture fleeting moments easily, despite a lack of continuous autofocus tracking. Olympus’s 1 fps and slower AF make it frustrating here. The similar zoom reach keeps subject size comparable.

Sports Photography

Dynamic sports scenes require swift focus and framing.

Again, Sony’s speed advantage is clear. Moreover, its center-weighted metering helps in tricky lighting, while Olympus lacks exposure compensation to fine-tune brightness. Neither camera is ideal for professional sports but Sony better serves enthusiasts.

Street Photography

Here, discretion, portability, and low-light performance matter.

Olympus’s smaller size lets you carry it easily for casual strolls, though Sony’s build isn’t too bulky either. In dim light, Sony’s superior ISO handling (up to 12800 vs. Olympus’s 1600 max native ISO) gives cleaner shots without a flash. Both lack silent shutter modes, so stealth is limited.

Macro Photography

Close-up shooters need precise focusing and stability.

Both cameras focus down to 1 cm, but Sony’s manual focus guidance and sharper lens edges give an edge. Olympus’s sensor-shift stabilization helps here, but on a tripod this is less critical.

Night and Astro Photography

Low noise at high ISO and slow shutter support matter for night shooting.

Olympus maxes out at ISO 1600, resulting in noisy images. Sony’s ISO 12800 potential offers flexibility, though noise is still present at top ISOs. Both have shutter limits (Olympus max shutter at 1/2000 s to 4 s, Sony 1/1600 s to 30 s) sufficient for creative exposure. Neither supports RAW output, restricting post-processing.

Video Capabilities

Video recording capabilities often make or break compact superzooms for hybrid shooters.

Sony leads with Full HD 1920 x 1080 recording at 60 fps using MPEG-4 and AVCHD formats. Olympus lags with max 1280 x 720 resolution at 30 fps, encoded in Motion JPEG - resulting in larger file sizes and lower quality. Neither camera offers microphone input or headphone monitoring.

Stabilization during video is effective on both but Sony’s optical system produces smoother footage. If video is a priority, Sony clearly wins hands down.

Travel Photography

A travel camera must be versatile, lightweight, and have decent battery life.

Both cameras accept SD/SDHC/SDXC cards, but Sony’s additional Memory Stick compatibility could be beneficial for some users. Battery life also favors Sony’s HX20V (320 shots vs. Olympus’s 220) - a significant benefit while on the go.

Sony’s GPS tagging adds value for travel memories, a feature absent on Olympus. Physically, Olympus is slightly smaller, but Sony remains compact and manageable.

Professional Work

For professional use, reliability, advanced controls, and file formats matter.

Neither camera supports RAW file capture, which limits their suitability for professional image editing workflows. Sony’s manual exposure modes and exposure compensation partially mitigate this, but Olympus stays at a basic automation level. No weather sealing on either means caution in demanding jobs.

Sony’s expanded video specs and GPS tagging add workflow benefits for multimedia professionals.

Connectivity, Storage, and Power

Both cameras offer Eye-Fi support for wireless image transfer - a useful but dated feature today. Neither has Bluetooth or NFC.

USB 2.0 and HDMI ports are present on both for image download and external display. Olympus uses the LI-50B battery pack; Sony utilizes NP-BG1, with Sony’s battery rated for about 320 shots per charge, significantly surpassing Olympus’s 220-shot rating - an important consideration for extended shoots.

Each sports a single storage slot compatible with SD standard cards, but Sony’s dual compatibility with Memory Stick adds flexibility based on user equipment.

Performance Scores and Genre Rankings

Drawing on performance metrics and my hands-on testing:

Sony HX20V outperforms Olympus SZ-10 in autofocus speed, image quality, low-light ability, and versatility, reflected in higher overall scores.

Looking deeper into genre-specific strengths:

Sony dominates wildlife, sports, and video shooting. Olympus holds its own minimally in street and macro photography for casual users prioritizing simplicity.
