Comparing two small yet distinct digital cameras from Olympus and Sony in the 2010s - what can we learn? I recently spent several weeks testing the Olympus SZ-10 superzoom compact alongside Sony’s RX100 IV, one of the most celebrated large-sensor compacts of its era. Both cameras share the point-and-shoot spirit but cater to vastly different audiences and photographic ambitions. In this detailed comparison, I’ll walk you through everything from sensor tech and autofocus prowess to real-world handling and genre performance - sharing firsthand insights from my studio, city streets, vast landscapes, and beyond.

If you’re weighing an affordable superzoom against a pricier, pocketable powerhouse, this deep dive will clarify which one suits your shooting style, budget, and expectations.

Size Matters: Portability and Ergonomics in Hand

A camera’s physical footprint and feel drastically affect how you engage with photography day-to-day. The Olympus SZ-10 sports a classic compact body that’s slightly elongated, precisely because of its massive 18x zoom lens. Meanwhile, the Sony RX100 IV is built more like a chunky point-and-shoot but with a distinctly premium finish and superior build quality.

Olympus SZ-10 vs Sony RX100 IV size comparison

Handling the SZ-10, I noticed the light weight (215 grams) made it an easy grab-and-go for casual outings, yet the body feels a bit plasticky and toy-like, particularly around its zoom mechanism. It’s modestly comfortable for snapshots but not for prolonged shooting sessions. The buttons are minimalistic and flat - great for simplicity but lacking tactile feedback.

In contrast, the RX100 IV weighs in at 298 grams, noticeably heavier, but it feels solid and confidently built in hand. Despite its slightly taller profile (102x58x41mm), Sony’s use of metal and rubberized grips creates a reassuring hold, almost bordering on premium compact camera ergonomics. The tilting screen is a welcome ergonomic feature for shooting at odd angles or selfies, which the SZ-10 lacks altogether.

Under the Hood: Sensor and Image Quality Showdown

Perhaps the most defining difference between these two cameras lies within their image sensors - a crucial factor that defines all subsequent image quality attributes.

Olympus SZ-10 vs Sony RX100 IV sensor size comparison

The Olympus SZ-10 sports a 1/2.3-inch CCD sensor measuring 6.17x4.55 mm, packing 14 megapixels. This type of sensor was common in budget compacts of its time. It delivers decent daylight performance, but noise control and dynamic range severely lag behind modern standards.

On the other hand, the Sony RX100 IV houses a significantly larger 1-inch BSI-CMOS sensor (13.2x8.8 mm) with 20 megapixels. The considerable sensor area - four times bigger than the Olympus’ - means the RX100 IV excels in low-light scenarios, has better depth rendering, and captures broader dynamic range. Sony’s back-illuminated design further enhances light gathering, improving ISO performance.

During my tests, this translated into images from the RX100 IV exhibiting fine detail, vibrant but natural colors, and minimal noise up to ISO 3200. Conversely, the SZ-10 images showed early noise obtrusion beyond ISO 400, reduced sharpness, and tighter latitude in post-processing.

Finding The Focus: Autofocus and Shooting Responsiveness

Autofocus performance can often be make-or-break, especially for moving subjects or spontaneous moments.

Both cameras offer face detection for portraits, but the RX100 IV boasts 25 focus points and supports continuous AF with impressive tracking capabilities. Its hybrid contrast-detection system is fast and confident, even in dim environments - a testament to its advanced Bionz X processor.

The SZ-10 provides only single autofocus, relying mainly on contrast detection with fewer focus points. It occasionally hunts in low light or on complex subjects, and continuous autofocus is absent. Having relied on the Olympus for quick candid shots, I found the lag frustrating when subjects moved abruptly.

Continuous shooting speeds are unequal, too - the SZ-10’s 1 fps is virtually symbolic, ideal only for static subjects or casual shooting. Sony’s RX100 IV crushes that with a rapid 16 fps burst mode, perfect for capturing fast-action wildlife or sports sequences.

Build and Controls: Balancing Simplicity Versus Creative Flexibility

When I placed the two side by side, the differences in top plate controls and overall design philosophy became clear.

The Olympus sticks to the basics: a zoom lever, shutter button, and a mode dial with limited options. There’s no dedicated manual exposure control or aperture priority, locking users into automatic or point-and-shoot modes. This could appeal novices or those who just want hassle-free shooting but limits creative expression.

The RX100 IV features direct aperture, shutter speed, and exposure compensation controls, plus customizable buttons for quick access. You can switch to full manual mode, aperture priority, shutter priority - significantly elevating potential for creative photography. For someone who enjoys tweaking settings on the fly, Sony’s design wins hands-down.

Screen and Viewfinder Magic: Composing Your Shots with Confidence

Both cameras offer a 3-inch screen, but the quality, resolution, and usability couldn’t be more different.

Olympus SZ-10 vs Sony RX100 IV Screen and Viewfinder comparison

Olympus’ SZ-10 screen resolution stands at 460K dots - adequate but grainy and with limited clarity under bright daylight. It’s fixed, lacking touchscreen functionality, making menu navigation slightly clunky.

Sony’s RX100 IV sports a high-res 1229K dot tilting LCD. Colors are vibrant and preview image sharpening impressively close to final JPEGs. Having a tiltable screen was invaluable when I shot landscapes low to the ground or quick street portraits from hip height.

Equally important, the RX100 IV has a built-in electronic viewfinder (EVF) with 2.35 million dots resolution and full 100% coverage, a feature completely missing in the SZ-10. For precise framing, composition verification, and shooting in bright glare, this EVF is a game changer.

Real-World Performance Across Photography Genres

Let’s now consider how these cameras perform across typical photographic styles drawing from my extended field tests.

Portraits: Rendering Skin Tones and Bokeh

Portrait photography hinges on nuanced skin tone reproduction, sharp eye focus, and appealing bokeh.

The RX100 IV’s larger sensor and bright lens (F1.8 aperture at the wide end) provide smooth background blur that helps isolate subjects beautifully. Sony’s advanced face detection and subtle eye AF feature consistently lock focus on subjects’ eyes with impressive accuracy. Color rendition favors natural yet punchy skin tones, which I appreciated during both indoor portraits and outdoor golden hour shoots.

In contrast, the SZ-10 shows noticeably less subject separation due to smaller sensor and slower lens (maximum F3.1). Its face detection works but occasionally misses focal precision. Skin tones tend to look flatter and somewhat washed out, especially indoors or under mixed lighting.

Landscape: Resolution, Dynamic Range, and Weather Sealing

Sharpness, detail, and dynamic range critically impact landscape images.

Sony’s RX100 IV, with 20MP resolution and a broad dynamic range (approximately 12.6 EV), excels in capturing expansive scenes with strong highlight and shadow detail recovery. Its RAW capture support also means you can squeeze extra latitude in post-processing - a must for serious landscape photographers.

The SZ-10’s sensor falls short here. Limited dynamic range and fixed JPEG output restrict post-processing flexibility. Its resolution is decent but cannot match the RX100 IV for crisp detail retention.

Neither camera offers environmental sealing or weatherproofing, so I treated both carefully during early morning dew and windy conditions.

Wildlife and Sports: Autofocus Speed, Telephoto Reach, and Burst Rate

For wildlife and sports enthusiasts, the 18x zoom on the SZ-10 (28-504mm equivalent) initially seems enticing, especially at budget prices. In my trials, however, the lens sharpness falls off noticeably beyond 200mm, and sluggish autofocus undermines quick capture opportunities. The 1 fps burst rate makes action photography almost impossible.

The RX100 IV’s shorter zoom range (24-70mm equivalent) limits reach but compensates with stellar autofocus tracking and 16 fps continuous shooting with AF/AE tracking. Coupled with superb image quality and low-light sensitivity, the RX100 IV performs admirably for near-to-mid telephoto action photos, especially in well-lit conditions.

If telephoto reach is paramount (say, birdwatching or soccer), the SZ-10’s zoom advantage is real but costs in IQ and speed are steep.

Street Photography: Discreetness and Low Light Handling

Street photographers often prioritize compactness, quick AF, and inconspicuous handling.

The SZ-10’s shape and zoom length draw some attention, and its noisy zoom motor adds to the footprint. Moreover, it struggles in dimly lit urban scenes.

Conversely, the RX100 IV’s pocketable size, quiet operation, fast autofocus, and clean high ISO performance make it an excellent street camera. The tilting screen also allows some creative framing while remaining discreet.

Macro and Close-Up: Magnification and Focusing Precision

The SZ-10’s macro capability boasts an impressive focus distance of 1 cm, achieving striking close-ups of textures and flora.

The RX100 IV allows close focusing at 5 cm minimum but still produces outstanding detail thanks to sharper optics and sensor resolution. Optical image stabilization on the Sony helps keep shots crisp despite handholding at close range.

If you’re macro obsessed on a budget, the SZ-10’s ultra-close focus wins. However, for overall sharpness and less limiting working distances, RX100 IV is superior.

Night and Astro: Noise Control and Exposure Options

Night sky and astrophotography demand sensors that can handle high ISO and long exposures elegantly.

The SZ-10 caps at ISO 1600 natively and lacks manual exposure controls (no bulb mode). I found noise at ISO 800 quite intrusive, limiting night photography options. Its brightest aperture is F3.1 - not ideal for gathering starlight.

Sony’s RX100 IV supports ISO up to 12800 (native) and extended ISO 25600. Manual modes, exposure bracketing, and longer shutter speeds (up to 30 seconds) empower astrophotographers. While a small sensor by pro standards, its BSI-CMOS sensor and superior noise performance make it a capable entry-level astro camera.

Video Features: Capturing Motion with Style

Video quality often separates average cameras from versatile multimedia tools.

The SZ-10 shoots modest 720p HD at 30fps, stored in Motion JPEG format with no advanced frame rate options or manual control over exposure. While serviceable for casual video, I considered it dated.

Sony’s RX100 IV records 4K UHD video up to 30p, 1080p up to 60p, and even 120 fps slow-motion. It uses XAVC-S codec providing better compression and image quality. Optical image stabilization smooths hand-held footage effectively. Although professional audio inputs are absent, the RX100 IV remains well-equipped for serious vloggers and filmmakers on the go.

Battery Life, Storage, and Connectivity: What Fuels Your Workflow?

Both cameras use proprietary battery packs meeting typical compact camera endurance: Olympus rated for 220 shots, Sony stretching to 280 shots per charge. In real use, I found the RX100 IV’s slightly better battery life helpful for extended trips without chargers.

Storage-wise, both use SD cards, but the Sony offers compatibility with Memory Stick duo formats as well.

Wireless connectivity is a decisive factor today: the SZ-10 supported Eye-Fi cards but lacked built-in Wi-Fi or Bluetooth, limiting instant sharing.

In contrast, the RX100 IV builds in Wi-Fi with NFC capability, easing transfers to smartphones and remote camera control via apps. This contemporary convenience adds a layer of workflow efficiency.

Price Versus Performance: Where Does Your Investment Go?

When new, the Olympus SZ-10 hovered around $300 - a budget-friendly superzoom tempting for casual shooters prioritizing range over image quality.

The Sony RX100 IV’s MSRP was near $900, clearly targeting enthusiasts or professionals needing a compact backup or main camera with exceptional versatility and image quality.

The value proposition depends heavily on your priorities:

  • If zoom reach and affordability matter most, SZ-10 delivers with caveats in IQ and responsiveness.
  • For image quality, autofocus, video, and creative control, RX100 IV offers a harder-to-beat compact but at three times the cost.
