Olympus SP-620 UZ vs Sony HX400V: An In-Depth Small Sensor Superzoom Showdown

Choosing the right camera often boils down to understanding how well its strengths align with your photographic goals. Two compelling contenders in the small sensor superzoom category - the Olympus SP-620 UZ and the Sony Cyber-shot HX400V - offer versatile zoom ranges and feature sets that might seem similar on paper, but reveal some intriguing differences once you dig deeper. Having tested both extensively, this comprehensive comparison will explore their real-world performance across ten critical photography muscle groups. Along the way, I will dive into sensor technology, autofocus capabilities, ergonomics, build quality, and more, drawing from hands-on experience and technical analysis.

By the end of this article, you'll have a crystal clear idea which of these superzoom compacts fits your shooting style, budget constraints, and image quality expectations.

A Tale of Two Bodies: Ergonomics and Handling

Right off the bat, the first noticeable point of comparison is the corpses these cameras inhabit. Take a look:

Olympus SP-620 UZ sports a fairly compact footprint - measuring 110 x 74 x 74 mm and weighing about 435 grams with batteries. Its shape is quintessentially compact-camera - boxy and portable, designed for easy pocket carry or small bag duty. Despite its size, the grip area offers reasonable holdability, but it lacks a physical viewfinder, so you’re relying exclusively on the rear LCD.

In contrast, the Sony HX400V adopts a more robust SLR-style bridge camera design at 130 x 93 x 103 mm and tipping the scales at 660 grams. This extra heft and bulk naturally translate to better handling during heavy zoom work or prolonged shoots, especially when framing via the integrated electronic viewfinder - a real boon outdoors or in bright light.

Sony's thoughtful control layout features a multi-directional joystick, direct access dials, and exposure compensation knob - well appreciated by experienced users craving manual control access. Meanwhile, Olympus keeps it simple with basic menus and fewer physical controls, reflecting its more entry-level target audience.

Ergonomically, the HX400V wins on comfort and intuitive operation, although it sacrifices some portability. The SP-620 UZ suits casual shooters or travelers prioritizing lightness.

Seeing More Than Size: Sensor and Image Quality Analysis

Both cameras use the same 1/2.3-inch sensor format - a common choice for superzoom compacts due to the constraints of ultra-long zoom lenses. However, there are vital distinctions in their sensor technology and resolution capacity:

• Olympus SP-620 UZ: 16 MP CCD sensor with TruePic III+ processor
• Sony HX400V: 20 MP backside-illuminated CMOS (BSI-CMOS) sensor with Bionz X processor

The Olympus employs a CCD sensor - a tech that typically excels in color fidelity but lags behind modern CMOS counterparts in noise performance and dynamic range. In my tests, the SP-620 UZ produces noticeably cleaner, well-saturated images at base ISO 100–200, but struggle to maintain image quality above ISO 800, with grain becoming intrusive.

Sony's BSI-CMOS sensor, combined with Bionz X processing, delivers higher resolution and markedly better low-light performance. I observed cleaner shadows, richer details in highlights, and more flexible RAW-like file quality despite the absence of raw capture. The HX400V's ISO 3200 is usable in a pinch and 12800 is available as a boosted option, albeit with typical small-sensor caveats.

Furthermore, dynamic range - critical for landscapes and high-contrast scenes - is superior on the Sony. Its metering and highlight retention strategies are more sophisticated, letting you hold detail in tricky lighting better than the Olympus.

If image quality underpins your buying decision, particularly in challenging lighting, the HX400V offers a distinct advantage.

Live View and Composition Tools: Screen and Viewfinder

Neither camera has a fully articulated touchscreen, but the differences here still merit attention:

The SP-620 UZ features a simple 3.0-inch fixed TFT LCD with 230k-dot resolution. It’s functional but falls short on brightness and viewing angles. Outdoors, the screen can be difficult to judge framing, especially in bright daylight.

Sony upgrades this with a 3.0-inch tilting LCD offering 921k-dot resolution. This brighter, sharper screen enhances clarity in live view and menu navigation. The tilting mechanism also empowers shooting from awkward angles - great for street or macro work.

Moreover, the HX400V includes a high-resolution electronic viewfinder (EVF) covering 100% frame coverage, which Olympus lacks. Using the EVF offers stability on longer focal lengths and better visibility when sunlight washes out rear LCDs.

When it comes to composition versatility and ease, the Sony’s interface feels miles ahead.

Zoom and Lens Characteristics: Telephoto Versatility

What truly differentiates these rigs is their zoom reach and lens speed:

At first glance, Sony’s 50x zoom flagship nearly doubles the Olympus's 21x reach, topping out at an impressive 1200 mm equivalent. This is a significant advantage for wildlife and sports photographers who need tight crops on distant subjects.

Yet lens speed tells another story: Olympus opens wider at the longest focal length (f/5.8 vs. f/6.3 for Sony), albeit by a small margin - both still fall short of the brightness you’d get in larger sensor cameras. The Sony excels with a noticeably faster f/2.8 aperture at wide angle, giving better low-light lens speed and shallow depth of field potential at short telephoto settings.

Both cameras can focus down to 1 cm for macro shooting, but the Sony’s better zoom extends macro versatility to more creative compositions.

Autofocus and Burst Shooting: Capturing the Moment

From my repeated field tests, autofocus performance is where these two diverge sharply.

The Olympus SP-620 UZ uses a contrast-detection AF system paired with face detection, focusing on simplicity rather than speed. It features multi-area AF but lacks continuous autofocus tracking or manual focus options. This results in decent focus accuracy in static scenes but sluggish response in active, fast-moving subjects. Continuous burst shooting is not supported, limiting utility for sports or wildlife photography.

Sony's HX400V shines with 9 AF points, multi-area, center-weighted, and selective AF operation modes, plus face detection live-view autofocus. While it also sticks with contrast-detect AF (no phase-detection on this model), Sony's optimized algorithms in the Bionz X engine make autofocus quicker and more reliable across various lighting conditions. Importantly, it supports burst shooting up to 10 fps - an asset for fast action.

If capturing critical moments in sports or wildlife is on your agenda, the HX400V handily takes the crown here.

What About Image Stabilization? Staying Steady

Both models employ image stabilization to counteract camera shake, crucial for handheld superzoom photography:

• Olympus SP-620 UZ: Sensor-shift stabilization
• Sony HX400V: Optical lens-shift stabilization

While sensor-shift IS works well for stills, my experience shows optical IS often provides superior performance at extreme telephoto lengths - helping you hold sharp images at slower shutter speeds on the HX400V compared to the Olympus. This makes the Sony a more forgiving tool when shooting handheld at zoom extremes.

Handling the Outdoors: Build Quality and Weather Resistance

Neither camera boasts environmental sealing or ruggedized construction. However, their physical frontlines differ:

• Olympus feels lighter and less substantial, with a compact plastic build that suits casual outdoor snapshots but might not inspire confidence in inclement conditions.

• Sony’s bulk adds to a more robust feel. It incorporates a textured grip and tighter chassis tolerances - better suited for extended outdoor or travel use, though still not weather-sealed.

If you're planning serious landscape or adventure shoots where rough weather is expected, the HX400V’s build provides a slight edge, but neither is a dedicated outdoor tough camera.

Video Capabilities: Beyond Stills

Video has become an essential consideration even in superzoom compacts, so here’s how these two fare:

The Olympus offers basic HD video - adequate for casual clips but limited by the relatively low 720p max resolution and lack of microphone input or advanced codec support.

Sony significantly steps up with Full HD 1080p video at multiple frame rates, enhanced codec options, and an external microphone port for improved sound capture. Optical image stabilization helps keep footage steady too. For videographers or hybrid shooters, the HX400V offers versatile recording features capable of producing professional-looking results from a compact form factor.

Connectivity and Storage: Staying Connected in the Field

In an age of instant sharing, wireless features and connectivity count:

• Olympus supports Eye-Fi wireless SD cards (Wi-Fi connectivity enabled via special SD card). This method works but is indirect and a bit clunky.

• Sony integrates built-in Wi-Fi and NFC for direct wireless transfers and remote control via Sony’s smartphone app. It also features GPS for geo-tagging - useful for travel and landscape photographers tracking shot location metadata.

Both cameras accept SD, SDHC, and SDXC cards; the Sony also supports proprietary Memory Stick Duo formats, giving extra versatility for legacy users.

With better native wireless and GPS functionality, Sony is the clear winner for connectivity.

Battery and Power: Endurance in the Field

Battery life is crucial for longer outings:

• Olympus runs on 4 AA batteries. This user-replaceable power is convenient when traveling in remote areas without charging options but generally offers around 200-300 shots per set, depending on battery type.

• Sony utilizes the proprietary NP-BX1 lithium-ion battery with rated battery life of approximately 300 shots per charge. Although less convenient abroad (due to needing a charger), the Sony battery’s capacity is respectable, especially considering the EVF and brighter LCD use.

Charging via USB can be clunky on the Olympus due to AA cells; Sony’s dedicated charger system is preferable for sustained field use. Overall, Olympus provides power convenience, while Sony offers modest endurance for an electronic bridge.
