Olympus SP-820UZ vs Sony NEX-5T

Exploring Two Unique Worlds: Olympus SP-820UZ vs Sony NEX-5T Detailed Review and Comparison

When it comes to selecting a camera for your photography adventures, the choices can often feel overwhelming - especially when models come from distinct categories serving different user priorities. Today, I’m diving into a comprehensive side-by-side assessment of two cameras that, on paper, couldn’t be more different: the Olympus Stylus SP-820UZ, a superzoom compact focusing on long reach and simplicity, and the Sony Alpha NEX-5T, an entry-level mirrorless marvel aimed at enthusiast shooters craving flexibility and image quality. Having logged many hours testing and shooting with both, I’ll break down where these cameras deliver, where they fall short, and most importantly, help you decide which might fit your specific photographic needs.

Breaking Down the Form Factor: Size, Build, and Handling

Right off the bat, the physical attributes of these two cameras tell quite a story. The Olympus SP-820UZ embraces the “bridge” camera ethos - relatively compact but substantial, delivering a considerable zoom, and designed for ease of use. It measures 117 x 78 x 93 mm and weighs a hefty 485 grams. By contrast, the Sony NEX-5T, although larger than most point-and-shoots, is considerably sleeker and lighter at 111 x 59 x 39 mm and 276 grams, a difference that’s immediately noticeable when you hold both. With its rangefinder-style mirrorless design, the NEX-5T focuses on portability without sacrificing image quality or control options.

Handling-wise, the SP-820UZ’s heft gives a secure, “stay-put” feel, albeit with a physique that some might find bulky for travel or street photography, where discretion and comfort matter. The NEX-5T’s minimalist frame is remarkably ergonomic, with well-placed control dials and a tilting touchscreen that easily adapts to challenging shooting angles - a nod to Sony’s careful design targeting enthusiasts and travelers alike.

The ergonomics battle slightly favors Sony, thanks to its dedicated exposure controls - shutter and aperture priority, plus full manual exposure - versus Olympus’s simpler interface with no manual exposure or shutter speed priority modes. For photographers who demand interaction with exposure parameters, the NEX-5T is clearly ahead here.

Sensor Tech: The Heart of Image Quality

At the core of any camera’s performance lies its sensor, and here the gap is pronounced. The Olympus SP-820UZ’s 1/2.3-inch 14-megapixel CMOS sensor, measuring just 6.17 x 4.55 mm (about 28.07 mm²), is typical for superzoom compacts of its generation. The tiny sensor size, while enabling a massive 40x zoom range - from 22 mm to a jaw-dropping 896 mm equivalent - presents physical constraints, particularly visible in low light and dynamic range capabilities.

The Sony NEX-5T boasts a significantly larger APS-C format sensor at 23.4 x 15.6 mm (365.04 mm²) and 16 effective megapixels. This sensor is over 13 times larger in area than Olympus’s, a massive advantage for capturing detail, preserving tonal gradations, handling noise, and extending dynamic range.

What does this mean in practice? The Olympus struggles to compete beyond brightly lit scenarios, showing limited DR flexibility and early onset noise above ISO 400. The NEX-5T, conversely, produces superb image quality for its category with a measured DXOMark overall score of 78, excellent color depth (23.6 bits), dynamic range (13 EV), and low-light performance rated at ISO 1015. This translates to cleaner images at higher ISO settings and the ability to recover detail in shadows and highlights - critical for professional-grade landscape and portrait work.

In portraits, for example, the NEX-5T’s sensor handles nuanced skin tones far more gracefully, while the SP-820UZ’s smaller sensor compresses tonal transitions, causing flatter renditions.

Lens and Zoom Capabilities: Reach vs. Flexibility

Any superzoom camera’s key selling point is obvious: massive zoom reach. The Olympus’s 40x optical zoom (22–896 mm equivalent) is impressive, and I have found it a boon for wildlife, travel, and even sports photography when you need to grab a distant subject quickly, no lens swapping required. However, this comes with trade-offs - the lens’s variable aperture from f/3.4 at wide-angle to f/5.7 at telephoto limits low-light ability, and image quality typically dips at longer focal lengths due to diffraction and lens compromises.

The Sony NEX-5T, however, is a lens-mount system camera with access to over 120 native Sony E-mount lenses, ranging from ultra-wide primes to long telephotos. This wealth of options enables far greater creative control and optical quality. Though out-of-the-box it ships body-only, pairing it with a quality 16–50mm kit lens already covers versatile focal lengths while maintaining superior sharpness and wider apertures.

From macro photographers’ perspectives, neither the Olympus fixed lens nor the standard Sony kit lens offers exceptional close-focusing magnification, but the NEX system’s lens ecosystem allows users to select dedicated macro optics with precise manual focus capabilities - something the Olympus’s fixed lens and limited AF system don’t support.

Autofocus, Speed, and Shooting Experience

The SP-820UZ uses a contrast-detection autofocus with face detection but lacks features like continuous AF, tracking, or eye-detection AF. In practical terms, this means it works fine for stationary subjects but struggles with moving targets or action sequences. Its continuous shooting speed maxes out at 2 frames per second, suited only to slow-paced shooting. Its shutter speeds range from 4 to 1/2000 sec, limiting creative control in very bright or fast-action conditions.

The Sony NEX-5T, with its hybrid AF system combining contrast and phase detection across 99 points (25 cross-type), delivers rapid, accurate focus locking and tracking, even in burst mode at 10 fps. It supports face detection, live tracking, and eye AF, making it far more capable for wildlife, sports, and candid street photography. This autofocus sophistication significantly enhances keeper rates in challenging scenarios.

Display and Viewfinder Usability

Both cameras sport 3-inch LCD screens, but here, the NEX-5T’s display is superior - tiltable for upwards or downwards angles, with a sharp 922k-dot resolution and touchscreen functionality. This makes composing shots at awkward angles - say, waist level or overhead - much easier and more intuitive.

The.SP-820UZ has a fixed 460k-dot TFT LCD, lacking touch input or tilt options, somewhat hampering usability in dynamic shooting conditions.

Neither camera includes an electronic viewfinder as standard, but the Sony NEX-5T supports an optional EVF via accessory mount, offering another compositional aid that professionals might appreciate - especially under bright sunlight.

Video Features and Capabilities

The Olympus SP-820UZ can record Full HD 1080p video at 30fps and supports slow-motion capture at VGA and below resolutions. Video codecs include MPEG-4 and H.264. However, it lacks manual video exposure controls, microphone input, or advanced stabilization - limiting its usefulness for serious video shooters.

The Sony NEX-5T is stronger here, recording Full HD 1080p up to 60 fps with AVCHD and H.264 codecs, opening better options for slow-motion and smoother playback. While it also lacks microphone and headphone jacks, its manual exposure controls during video and hybrid AF significantly improve video shooting capabilities.

Neither camera supports 4K or high-bit-rate video formats, but for casual or enthusiast filmmakers, the NEX-5T provides a more flexible and higher-quality experience.

Battery Life and Connectivity Options

In extended shoots, battery life can make or break a camera’s practical usability. The SP-820UZ’s battery info is less documented, but its compact body and simpler electronics suggest moderate endurance. The Sony NEX-5T, meanwhile, uses the NP-FW50 battery rated at around 330 shots - typical for mirrorless systems but shorter than DSLRs.

Both cameras feature a single SD card slot with SDHC/SDXC compatibility, but the NEX-5T also accepts Sony’s proprietary Memory Stick Pro Duo formats for expanded versatility.

For connectivity, the SP-820UZ offers only USB 2.0 with no wireless link, meaning offloading images requires cable tethering. The NEX-5T integrates built-in Wi-Fi and NFC, allowing quick image transfers to mobile devices - extremely useful for modern travel and social sharing demands.

Photography Use Cases: Which Cameras Deliver in Key Disciplines?

Portrait Photography

If capturing portraits - be it formal headshots or environmental portraits - is your focus, sensor size and lens flexibility dominate the priority list. Here the NEX-5T excels, with its APS-C sensor rendering skin tones with natural gradations and the aperture-priority/manual modes enabling precise control over depth of field and bokeh quality. Sony’s advanced AF with face and eye detection further ensures tack-sharp eyes - a crucial criterion.

The Olympus SP-820UZ can handle casual portraits but suffers in background separation and tonal nuance due to its small sensor and limited lens aperture. Its fixed zoom lens’s maximum aperture peaks at f/3.4 wide and f/5.7 telephoto - too narrow for exquisite bokeh effects.

Landscape Photography

Landscape shooters typically prize dynamic range, high resolution, and weather sealing. While neither camera offers robust environmental sealing, the NEX-5T’s larger sensor captures a greater tonal latitude and sharpness, allowing for detailed landscape photos, particularly in highlight/shadow recovery.

Resolution-wise, the 16MP NEX edges out Olympus’s 14MP sensor, though both cameras offer sufficient print size for web and moderate enlargements.

The Olympus’s 40x zoom is not particularly relevant for landscapes, where wider angles dominate. The NEX system’s ability to wield ultra-wide-angle lenses offers a definitive advantage.

Wildlife and Sports Photography

The enormous zoom reach of the SP-820UZ initially tempts wildlife and sports photographers - but autofocus speed and accuracy, along with burst shooting rates, matter more.

The Olympus delivers only 2 fps continuous shooting and basic contrast-detect AF, often resulting in missed shots of moving wildlife or athletes.

Conversely, the Sony NEX-5T’s 10-fps burst and hybrid AF with tracking capabilities make it far better suited for action, provided you have an appropriate telephoto lens. The early adoption of phase-detection AF in this mirrorless model offers a distinct edge in focus acquisition speed on moving subjects.

Street Photography and Travel

When hitting the city streets or traveling light, portability and discretion come into play. The NEX-5T’s compact, lightweight profile and silent shutter modes (with manual controls) enhance its candid shooting credentials. The tilting touchscreen helps when shooting inconspicuously or in cramped urban environments.

The Olympus’s bulkier frame and louder zoom operation make it less covert, yet its all-in-one superzoom solution appeals to travelers who want ‘point and shoot’ convenience without carrying multiple lenses.

Macro and Close-up Work

Neither camera is explicitly designed for macro work. The Olympus offers a close focusing distance of 1 cm, which is surprisingly good for a superzoom compact and facilitates some interesting close-up shots, albeit with less sharpness than dedicated macro lenses.

The NEX-5T’s macro capability depends heavily on lens selection. With access to high-quality macro primes, it can provide superior magnification and focusing precision, but at an added cost.

Night and Astrophotography

Here, sensor size and noise performance dominate. The Olympus’s tiny sensor with max native ISO 6400 produces noisy images beyond ISO 400-800, often limiting night shooting to well-lit scenes.

The Sony NEX-5T’s APS-C sensor and higher maximum sensitivity (ISO 25600 native) paired with better noise control open real possibilities in astrophotography and low-light environments, although its relatively modest lens ecosystem can constrain ultra-wide starfield captures unless additional accessories are invested in.

Professional Applications

For professional workflows, raw image support, color fidelity, control over exposure, and ergonomic reliability matter.

The Olympus SP-820UZ lacks raw capture and full manual controls, aiming instead at the casual enthusiast market. This limits its value in professional contexts where post-processing flexibility is vital.

The Sony NEX-5T supports raw files, exposure bracketing, full manual modes, and is compatible with professional editing workflows, making it a more suitable entry point for those seeking to expand their photographic skill and produce print-quality work.

Build Quality and Durability

Neither model offers weather sealing or rugged construction. Both require careful handling outdoors, especially in harsh conditions.

The Sony’s mirrorless chassis feels more refined, constructed of quality plastics and metals, while the Olympus, although solid, is unmistakably a value-priced compact.

Quick Recap: Performance and Scoring by Genre

Looking at genre-specific strengths, the Sony NEX-5T leads comfortably in portraits, landscapes, wildlife, and sports due to sensor quality and AF prowess. Meanwhile, the Olympus finds modest success in travel and casual wildlife where zoom range and simplicity supersede image quality needs.

Summarizing overall performance, the Sony’s higher DXO Mark sensor scores and richer feature set place it well above the older Olympus in imaging potential and creative versatility.

Price and Value Considerations

When launched, Olympus’s SP-820UZ was priced around $299, while the Sony NEX-5T started at approximately $399 body-only. Today, both can be found used or refurbished within similar price brackets - a critical factor for budget-conscious buyers.

Choosing depends on how you prioritize zoom reach vs. image quality and system expandability.

Verdict: Aligning Your Camera Choice with Your Photographic Goals

If you seek a simple, affordable camera with an enormous zoom that lets you get close to distant subjects in a compact package - and you mostly shoot casual outdoor scenes with plenty of light - the Olympus SP-820UZ remains a respectable choice.

However, if your ambitions lean toward creating higher-quality images with impressive color depth and dynamic range, shooting a wider range of genres including portraits, landscapes, and action, and you appreciate manual control with lens versatility, the Sony NEX-5T emerges as the clear winner. Its mirrorless design ushers in more future-proofing and a pathway into serious photography.

Our hands-on testing confirms that the NEX-5T's real-world advantages in autofocus speed, image quality, and user interface deliver more satisfaction, although it entails a steeper learning curve and additional investment in lenses.

In brief: Olympus SP-820UZ is an all-in-one point-and-shoot with mega zoom; Sony NEX-5T is a compact mirrorless system for those serious about image quality and creative flexibility.
