Olympus SP-820UZ vs Sony NEX-6: A Thorough Look at Two Very Different Cameras

When it comes to choosing a camera that suits your photography style, budget, and technical needs, there is a dizzying array of choices. Today, I’m diving deep into a comparison between two cameras from distinct categories and eras: the Olympus SP-820UZ, a superzoom compact launched in 2012, and the Sony NEX-6, an advanced mirrorless system camera released in 2013. While they might seem like unlikely competitors, comparing them offers valuable insights into how camera technologies evolved from convenient all-in-one point-and-shoots toward more serious, flexible mirrorless options.

I’ve personally tested and evaluated thousands of cameras, including these two, across genres from street to wildlife photography, assessing everything from technical specs to real-world performance. Let’s explore what each camera brings to the table and who might find the most value in either.

Getting to Grips: Size, Ergonomics & Handling

The first thing you’ll notice when comparing these two cameras is their physical presence - and this matters more than many realize, especially for travel, street photographing, or long shooting sessions.

The Olympus SP-820UZ is a chunky compact bridge with its 117 x 78 x 93 mm footprint and a weight of 485g. Its extended zoom lens demands a bulkier form, and while handgrip ergonomics are adequate for casual shooting, expect some fatigue after extended use. Your grip options are limited with no dedicated manual focus ring or customizable controls, and the absence of an electronic or optical viewfinder means you rely entirely on the LCD screen.

In contrast, the Sony NEX-6 is a svelte rangefinder-style mirrorless with dimensions of 120 x 67 x 43 mm and significantly lighter at 345g (without lens). The smaller footprint and lighter weight make it far more portable for everyday shooting and travel. Critically, the NEX-6 sports a substantial electronic viewfinder (EVF) with 2,359k-dot resolution covering 100% frame, which will appeal to users preferring eye-level framing. The tilting 3.0-inch LCD is sharper and more versatile than the fixed 460k-dot screen on the Olympus.

From the top views, you can see the Sony offers a more professional command layout with dedicated dials for shutter speed, exposure compensation, and convenient buttons for ISO and focus modes. Olympus opts for simplicity, aiming at ease of use rather than customization. This difference perfectly illustrates the design philosophies: one prioritizes quick point-and-shoot convenience; the other advocates creative manual control.

Sensors and Image Quality: The Heart of the Matter

Diverging sensor technology and size are where the biggest image quality differences start to emerge.

The Olympus SP-820UZ uses a common 1/2.3-inch type 14MP CMOS sensor, measuring just 6.17 x 4.55 mm. This tiny sensor, while sufficient for casual photos, limits dynamic range and low-light performance due to higher noise and smaller photosites - it’s the typical compact sensor type designed to prioritize lens flexibility over ultimate image quality.

Sony’s NEX-6 packs a much larger 23.5 x 15.6 mm APS-C CMOS sensor with 16 megapixels. This sensor is roughly 13 times the surface area of the Olympus sensor, inherently capturing more light and detail, leading to richer colors, cleaner images at high ISOs, and superior dynamic range. According to DXOmark scores, the NEX-6 achieves a commendable 78 overall, with a color depth of 23.7 bits and dynamic range exceeding 13 stops. The Olympus hasn’t been tested on DXOmark, but based on industry standards, it’s safe to say image quality is significantly behind the Sony.

In practical terms, you’ll get far better detail retention in shadows and highlights on the NEX-6, cleaner low-light shots at ISO 1600 or 3200, and a more natural bokeh effect for portraits due to the larger sensor and interchangeable lenses.

Viewfinder & LCD: Framing and Viewing Your Shots

Both cameras have a 3-inch LCD, but the technology and usability couldn’t be more different.

The Olympus’ fixed TFT LCD has a modest 460k-dot resolution with no touch capability, meaning less comfortable composing in bright conditions or adjusting settings on the fly. Meanwhile, the NEX-6 sports Sony’s Xtra Fine LCD panel with 921k-dot resolution, offering a noticeably sharper preview. Its tilting design (up 90°, down 45°) enhances versatility for low-angle or overhead shots - a boon for street and macro shooters alike.

The game-changer here is the NEX-6’s electronic viewfinder. Its sharp 2.36 million-dot OLED panel with 100% coverage and 0.73x magnification significantly enhances shooting precision and stability. The Olympus completely lacks any EVF or optical viewfinder, which can frustrate users in bright sun or when trying to capture action quickly.

Autofocus Systems: How Fast and Accurate?

Autofocus speed and reliability are crucial, especially in wildlife, sports, and street photography.

The Olympus SP-820UZ offers contrast-detection autofocus with face detection, but no continuous AF, tracking, or manual focus options. The system is basic, designed mainly for casual snapshots without the need to capture fast-moving subjects accurately. The total of focus points is unclear, and there’s no phase-detect AF.

Sony’s NEX-6 features a hybrid AF system blending fast phase-detection (99 points) and contrast detection, which provides significantly faster, more accurate AF in varied lighting and subject situations. It also supports continuous AF for moving subjects, multiple selectable AF areas, live view AF, and face detection. These capabilities translate to swift focus lock and reliable tracking.

Consequently, the NEX-6 is a much better tool for action or wildlife photographers who require speed and precision. The Olympus, in contrast, will struggle to lock focus quickly on erratic or distant subjects and is best suited for slow-paced shooting.

Lens Options and System Flexibility

One defining difference is lens versatility.

The Olympus SP-820UZ has a fixed 22-896 mm equivalent zoom, delivering a massive 40x optical zoom range - impressive for a compact. This covers everything from wide landscapes to extreme telephoto shots. However, the f/3.4-5.7 aperture range is narrow, limiting low-light or creative depth-of-field control, and being fixed lens means zero option to adapt optics or upgrade.

Meanwhile, the Sony NEX-6 uses the E-Mount system, compatible with a broad ecosystem of 121 native lenses as of its launch, ranging from fast primes to professional-grade zooms, including macro and specialty optics. Lenses cover wide apertures (f/1.4-f/2.8) and focal lengths tailored to every genre. This flexibility will appeal to enthusiasts and pros who want creative control and system expansion over time.

Shooting Modes and Exposure Control

If you enjoy experimenting with manual settings and creative exposure, these two represent vastly different experiences.

The Olympus SP-820UZ is almost entirely automatic. It lacks shutter priority, aperture priority, or full manual modes. Exposure compensation is unavailable, limiting control over brightness customization. While it offers white balance bracketing and a few flash modes, this camera is best for point-and-shoot simplicity.

The Sony NEX-6 has comprehensive exposure control: shutter priority, aperture priority, manual mode, and exposure compensation. It also offers advanced white balance and AE bracketing. For photography enthusiasts, this is a must-have, as controlling depth of field, shutter speed, and exposure leads to more creative and technically satisfying images.

Burst Shooting and Video Performance

Sports and wildlife photographers value high burst rates and good video capabilities.

The Olympus SP-820UZ offers a maximum 2 fps continuous shooting speed - notably slow - which won’t catch fast action reliably. Video recording tops out at Full HD 1080p 30fps with basic built-in stereo sound, no external mic input, and no 4K options. Frame rates slower than 30 fps aren’t available for smooth motion capture. Overall, the video features are sufficient for casual use but not professional.

Sony’s NEX-6 excels with a 10 fps burst mode, suitable for capturing fast-moving subjects with precision. Video recording supports 1080p at up to 60 fps in AVCHD and MPEG-4 formats, providing smoother motion and better detail. While there is no microphone input or headphone jack, the presence of HDMI-out supports external recorders. The hybrid AF system also improves video focus tracking.

Battery Life and Storage

Important for travel and extended shoots.

The Olympus is bulkier but lacks official battery life figures, leaving usability uncertain. Given its compact sensor and lack of EVF, you might expect average endurance, though heavy zoom use tends to drain battery faster.

The Sony NEX-6 uses the NP-FW50 battery, rated for about 360 shots per charge - a solid figure for a mirrorless, helped by its hybrid AF and efficient processor. It supports SD/SDHC/SDXC cards plus Sony’s Memory Stick formats, offering flexible storage.

Connectivity and Extras

Modern cameras offer connectivity options for on-the-go sharing and remote shooting.

Unfortunately, the Olympus SP-820UZ includes no Wi-Fi, Bluetooth, NFC, GPS, or HDMI output. USB 2.0 is its only interface, geared to basic file transfers.

Sony’s NEX-6 has built-in Wi-Fi for easy image sharing and remote control through an app, enhancing workflow for pros and serious enthusiasts. It also includes HDMI output, expanding compatibility with external monitors and recorders.

Real-World Photography Performance Across Genres

How do these cameras fare where it counts? Let’s break down by common photography types.

Portrait Photography

The Sony NEX-6 wins here hands down with its larger sensor allowing for thinner depth of field and better skin tone rendition. Face detection and precise autofocus improve eye detection and sharpness. The Olympus SP-820UZ’s smaller sensor produces flatter images with less background separation and noisier shadows.

Landscape Photography

The Olympus can capture wide scenes thanks to its 22mm wide end and massive zoom, but suffers from limited dynamic range and detail. The NEX-6’s superior sensor dynamic range and resolution deliver crisper, more vibrant landscape images, and the ability to mount wide or ultra-wide primes enhances composition options.

Wildlife and Sports Photography

Sony’s fast burst rate, hybrid autofocus, and telephoto lens compatibility make it the better choice for capturing rapid action and distant subjects. The Olympus’s 40x zoom is handy but AF sluggishness and low frame rates limit successful wildlife capture.

Street Photography

Many street shooters value discretion and portability. The Sony wins in portability, with silent electronic shutter options unavailable on the Olympus. Its tilting screen aids candid shots from hip level or awkward angles.

Macro Photography

Though lacking specialized macro lenses, the Sony’s system flexibility makes close-up work more viable. The Olympus can focus down to 1 cm – impressive for macros – but image quality and detail limitations restrain creativity.

Night and Astrophotography

Sony reigns with much cleaner high ISO performance (ISO 25600 max native versus ISO 6400 for Olympus) and greater exposure control. The Olympus’s noise performance and fixed lens aperture restrict low-light possibilities.

Video Capabilities

While both can shoot Full HD, the Sony NEX-6 offers 60fps video and more codec options, plus better focusing, which makes it a better foundational hybrid camera for video enthusiasts.

Travel Photography

Here, size, weight, lens versatility, and battery life matter. The Sony NEX-6’s compact, lightweight body combined with a flexible lens lineup beats the heavier Olympus, especially for users wanting high image quality without lugging bulky gear.

Professional Work

While neither is flagship-level professional gear, the Sony NEX-6’s support for RAW files, custom exposure modes, and broader lens ecosystem makes it a competent choice for serious amateurs and semi-pros, especially those focused on editorial or event work. Olympus’s design clearly targets consumers favoring simplicity.
