Olympus Stylus SH-3 vs Sony RX10 III: A Hands-On Deep Dive Into Two Superzoom Compacts

Choosing the right superzoom camera is a balancing act between portability, image quality, zoom capabilities, and versatility. Over my 15+ years of rigorous camera testing, I’ve handled everything from tiny pocket cameras to robust pro-grade models. Today, I'm dissecting two notable entrants in the superzoom compact / bridge camera category: the Olympus Stylus SH-3, a petite powerhouse tailored for travel and casual enthusiasts, and the Sony Cyber-shot RX10 III, a bulkier but much more advanced, large-sensor superzoom beloved by pros and serious hobbyists.

This comparison mixes detailed technical analysis, real-world shooting experience, and value judgments to help you figure out which camera suits your photographic passions - be it wildlife, portraits, nightscapes, or travel snapshots. I’ll also weave in sample images and specs side-by-side to illuminate each model’s strengths and compromises.

First Impressions: Size, Handling, and Design Reality

When I first picked up both cameras, the distinct design and size differences were immediately clear. The Olympus SH-3 is compact and pocketable, perfect for tossing into a day bag or even a jacket pocket. In contrast, the Sony RX10 III carries a solid, SLR-style heft, weighing nearly four times as much.

The SH-3’s physical dimensions (109x63x42 mm) make it nimble for street photography and casual shooting, though its grip and control layout lean towards simplicity, which I’ll get into shortly. The RX10 III is much larger (133x94x127 mm) and heavier at over 1 kg, primarily due to its large lens and weather-resistant metal body.

This size difference directly affects prolonged shooting comfort. The RX10 III’s substantial grip and textured controls are ergonomically designed for serious use - I could hold it steadily even during extended wildlife sessions. The SH-3 felt a bit cramped in comparison, but its light weight meant I rarely felt fatigued on relaxed photo walks.

Control Layout and Interface: Ease of Use Meets Responsiveness

Examining the top plate and handling controls gives insight into each camera’s user experience philosophy.

The Olympus SH-3 has a modest set of buttons and dials, aimed more at casual shooters or those preferring mostly automatic operation with some manual override. Its manual exposure mode exists but lacks dedicated aperture or shutter priority dials, meaning you’ll navigate settings via touchscreen or menus. The touchscreen itself is a neat addition, offering clearer, faster setting adjustments than many compact cameras I’ve tested at this price point.

By contrast, the RX10 III configures a classic three-dial setup: mode dial, control ring on the lens, and top control wheel. This camera feels like a DSLR bridge in terms of direct, tactile control - a big advantage when shooting fast action or complex scenes. The handling benefits from the tilting LCD and high-res electronic viewfinder, which the SH-3 lacks.

Sensor Technology and Image Quality: The Heart of the Matter

While superzooms often sacrifice sensor size for greater reach, the difference here is vast and a major factor in image quality and creative control.

• The Olympus SH-3 uses a 1/2.3” BSI-CMOS sensor measuring just 6.17x4.55mm with 16 megapixels - typical for compact superzooms but quite small.
• The Sony RX10 III houses a much larger 1” BSI-CMOS sensor measuring 13.2x8.8mm with 20 megapixels.

Sensor size translates to several practical differences. Larger sensors can capture more light, yielding better dynamic range, less noise at high ISO, and the ability to produce shallower depth of field for background separation. For instance, I observed dramatically cleaner night and low-light shots on the RX10 III at ISO 3200, whereas the SH-3 images started showing grain and color smearing beyond ISO 800.

The 16MP max resolution on the SH-3 is sufficient for social media and prints up to 8x10”, but the RX10 III’s 20MP sensor provides a clear edge in detail and cropping flexibility, useful for landscapes or portraits requiring nuanced sharpness.

Autofocus System: Speed and Accuracy in Real Conditions

Accurate, quick autofocus is paramount when shooting fast-moving subjects like wildlife, sports, or street scenes.

In controlled conditions, the SH-3 performed decently on static or slow-moving subjects, thanks to its contrast-detection AF and face detection system working reasonably well. However, when panning or tracking animals, especially birds in flight, the lag was noticeable - focus hunting disrupted sequences often.

Conversely, the RX10 III’s 25-point AF layout and advanced tracking algorithms delivered sharp focus nearly every frame at 14fps burst rate. I tested it on busy soccer matches and a local bird sanctuary - it locked on almost instantly and tracked unpredictable movement reliably. This makes the RX10 III a better investment if you want serious telephoto and action shooting capabilities.

Build Quality and Weather Resistance: Shooting in the Elements

For landscape, travel, or wildlife photographers, sturdy construction and weather sealing can be a deal maker or breaker.

• The Olympus SH-3 has a compact plastic body with no weather sealing or rugged protection. It’s designed mostly for casual, urban, or family snapshot use.
• The Sony RX10 III offers professional-grade weather sealing against dust and moisture, with a metal chassis that can handle moderate outdoor abuse.

While the SH-3 handled light rain and dusty conditions if careful, I wouldn’t risk it hiking in the mountains or coastal spray. The RX10 III, on the other hand, accompanied me on several drizzly forest hikes without issue, inspiring confidence for rougher environments and extended outdoor use.

LCD and Viewfinder: Framing Your Perfect Shot

The presence and quality of a display and viewfinder profoundly affect the shooting workflow.

The Olympus SH-3 sports a 3” fixed touchscreen LCD with decent 460k-dot resolution - bright and accessible but limited by its fixed angle and modest resolution. I occasionally struggled with visibility under harsh sunlight.

The Sony RX10 III expands usability with a 3” tilting LCD at 1.23M-dot resolution, which enables comfortable low-angle or over-the-head composition. In addition, it boasts a 2359k-dot OLED electronic viewfinder covering 100% of the frame. This EVF is indispensable on bright days and offers real-time exposure preview, assisting with manual focus and zone composition - features the SH-3 misses altogether.

Lens Performance: Zoom Range Meets Aperture and Sharpness

Both cameras offer a fixed superzoom lens with very similar focal length ranges (25-600mm equiv. for SH-3, 24-600mm equiv. for RX10 III), but their aperture, optical quality, and stabilization vary dramatically.

• The Olympus SH-3 lens has a max aperture ranging from f/3.0 at wide angle to f/6.9 at telephoto, indicating modest light-gathering ability, especially at long zoom.
• The Sony RX10 III lens is much faster - f/2.4 to f/4, enabling brighter viewfinder images, faster shutter speeds, and shallower depth of field control.

Both have macro focus to 3 cm, allowing close-up shots, though the larger sensor on Sony benefits from improved depth and detail rendition.

Image stabilization plays a vital role here. The SH-3 uses sensor-shift stabilization - effective but limited by its smaller sensor and lens speed. The RX10 III employs optical image stabilization integrated into the lens system, resulting in noticeably steadier handheld shots, especially at long focal lengths or slow shutter speeds.

Portrait Photography: Skin Rendering and Background Separation

I put both cameras through several portrait sessions to test skin tone reproduction, bokeh quality, and face/eye detection autofocus.

The Olympus SH-3 produces pleasant, slightly softer images with a warm tone palette - pleasant for family snaps but lacking in fine detail when composure is crucial. Its small sensor and slower lens limit background blur, resulting in busier, less isolated portraits.

The Sony RX10 III excels here with its large 1” sensor and faster lens, delivering beautifully smooth bokeh. Skin textures emerge naturally with less noise and better dynamic nuances. Its face detection autofocus was reliable but noticeably lacked eye detection autofocus, a feature introduced in newer models.

Landscape Photography: Detail, Dynamic Range, and Weather Robustness

Landscape photographers will appreciate the RX10 III’s superior image resolution and dynamic range - rated at 12.6 EV by DxO, far surpassing the SH-3’s modest sensor. This difference becomes evident when recovering highlight and shadow details in tricky light.

The Sony camera’s weather sealing further encourages outdoor adventure photography, while the Olympus requires more prudence.

Sports and Wildlife: Autofocus and Burst Shooting at Speed

In crowded stadiums and wildlife hideouts, I need quick focus and fast shooting.

• The SH-3 caps at 11.5 fps burst but with less reliable AF tracking.
• The RX10 III offers 14 fps with continuous AF, delivering sequences that more often hit the mark.

Combined with the faster lens and better high ISO control, the RX10 III outperforms for demanding sports and wildlife capture - though at the cost of increased weight and bulk.

Street and Travel: Discretion, Portability, and Battery Life

Street photographers prioritize discretion and quick access.

The Olympus SH-3’s diminutive size and silent-ish operation make it ideal for candid shots, blending into crowds, and slipping into tight spaces. Its battery life of 380 shots is adequate for day trips.

The RX10 III is more conspicuous, heavier, and requires a larger bag. It balances this with a longer battery life (around 420 shots per charge), excellent all-day reliability, and a versatile zoom range that ably handles everything from architecture to street portraits.

Macro and Close-Up: Detailing the Smallest Wonders

Both models feature 3 cm macro focus capabilities.

Thanks to the RX10 III’s sharper optics and larger sensor, macro images show better detail, color fidelity, and background isolation. The Olympus delivers acceptable close-ups but struggles to produce the creamy background blur that adds artistic impact.

Night and Astro Photography: ISO Performance and Exposure Modes

Low-light shooting puts the sensors through their paces.

The SH-3’s max native ISO of 6400 is respectable but produces significant noise beyond ISO 800, limiting usefulness for astrophotography or dim indoor portraits.

The RX10 III doubles max ISO to 12,800 native (expandable to 25,600), maintaining quieter images at higher ISOs thanks to its larger sensor and superior noise reduction algorithms. The RX’s electronic shutter also allows ultra-fast 1/32000s exposure to control bright scenes creatively.

Video Features: Recording Quality and Usability

Both cameras offer UHD 4K video, but with dramatically different capabilities:

• The Olympus SH-3 records 4K at 15 fps - more of a timelapse or multi-shot format than smooth video.
• The Sony RX10 III shoots 4K at 30 fps, with advanced codecs (XAVC S), microphone and headphone jacks, and full HD 60p modes for slow-motion.

The RX10 III’s superior video specs make it a practical hybrid for vloggers and filmmakers, while the SH-3 is limited to casual video capture.

Professional Use and Workflow: Raw Support and Connectivity

Both cameras shoot RAW - great for professional workflows. However, the RX10 III integrates better with tethered shooting setups and supports NFC for wireless transfer (SH-3 does not).

Battery options and storage support are comparable, but the RX10 III’s wider compatibility with Memory Stick Pro Duo and multiple SD cards offers flexibility.

What the Numbers Say: Overall and Genre-Specific Performance Evaluations

Though I rely primarily on real-world testing, it’s worth noting that DxOMark scores rate the RX10 III substantially higher - particularly for color depth, dynamic range, and low-light performance. This numerical edge translates into noticeable practical differences I experienced shooting portraits, wildlife, landscapes, and night scenes.
