Olympus SP-600 UZ vs Panasonic GH3: A Detailed Hands-On Comparison for Enthusiasts and Pros

Choosing a camera today can be overwhelming, especially with so many models spanning wildly different categories - from budget compacts to high-end mirrorless beasts. In this article, I’ll dive deep and compare two intriguing cameras that, at first glance, might appeal to very different users: the Olympus SP-600 UZ, a small sensor superzoom compact from 2010, and the Panasonic Lumix GH3, a serious advanced mirrorless Micro Four Thirds camera from 2012.

I’ve personally spent hundreds of hours testing cameras across the years, and here I’ll draw on that experience to help you understand the real-world differences, strengths, and tradeoffs of these two models. Whether you’re a casual snapshooter, a budding enthusiast, or a working pro weighing your options, this comparison will help you make an informed choice. Let’s get into it.

Getting to Know the Contenders: Form Factor, Build, and Handling

First impressions matter, and size, shape, and ergonomics play a big role in how happy you’ll be carrying and using a camera day to day.

The Olympus SP-600 UZ is a chunky compact superzoom with a fixed 28-420mm (35mm equivalent) lens. It’s definitely designed for users who want all-in-one flexibility without switching lenses or fussing over settings. Measuring 110 x 90 x 91 mm and weighing 455g, it’s relatively pocketable but chunky for a compact.

The Panasonic GH3 is a proper mirrorless interchangeable lens camera (MILC), resembling a DSLR in size and controls but lighter and more versatile in many ways. At 133 x 93 x 82 mm and weighing 550g (body only), it feels substantial in hand, with a thoughtful grip and robust build.

The image above clearly shows the SP-600’s stubby, compact form versus the GH3’s more traditional camera body. The GH3’s design includes a large handgrip and a layout optimized for serious photography sessions, with plenty of dials and buttons (more on that next). The SP-600 is simpler, geared toward casual shooters who prefer point-and-shoot ease.

Build quality? The GH3 offers weather sealing - a major bonus for shooting outdoors in challenging conditions. The SP-600 UZ has a plastic body with no environmental sealing, so it’s best kept dry and handled gently.

Ergonomics and controls: The SP-600 mostly forgoes advanced controls - no manual exposure modes, no aperture/shutter priority. The GH3, by contrast, features a comprehensive control scheme with shutter priority, aperture priority, manual exposure modes, customizable buttons, and an illuminated control dial. It caters to hands-on photographers who like full creative control.

Looking at the top view, you can see the GH3 sports traditional dials for mode, exposure compensation, and a cluster of function buttons within easy reach of your right thumb and index finger. The SP-600’s controls are much sparser, with zoom control dominating and limited exposure options.

In summary: If you want a grab-and-go all-in-one that’s simple but limited, the SP-600 fits the bill. If you prioritize strong ergonomics, durability, and the ability to grow your system with lenses, the GH3 is a clear upgrade.

Sensor and Image Quality: Bigger Sensors Still Win

Sensor tech is often the biggest determinant of image quality, especially in dynamic range, low-light performance, and detail. The cameras here couldn’t be more different in sensor size and tech.

The Olympus SP-600 UZ uses a tiny 1/2.3" CCD sensor measuring around 6.08 x 4.56 mm (~28 mm²) with 12 megapixels resolution. This sensor size is common in compact cameras and limits overall image quality, especially at higher ISO settings and in dynamic range.

The Panasonic GH3 sports a much larger Four Thirds CMOS sensor measuring 17.3 x 13 mm (~225 mm²) with 16 megapixels. While not as large as APS-C or full-frame, the GH3’s sensor offers a big leap in image quality and flexibility compared to tiny compact sensors.

When shooting side-by-side in good light, the GH3 produces images with noticeably more detail, improved color gamut, and richer tonal gradations. Noise levels start low and remain manageable up to ISO 1600 and beyond, while the SP-600’s CCD sensor noisy by ISO 400-800, limiting low light use.

Here are some technical highlights:

The ability to shoot RAW on the GH3 means you can extract much more detail and control tonal curves in post-processing compared to the SP-600’s compressed JPEG-only output.

Bottom line on image quality: The GH3 delivers substantially superior image quality, especially in low light and challenging conditions. If you value crisp images with rich colors and fine detail, the GH3 is worth the higher price and learning curve.

Autofocus and Performance: Speed Matters

For action or wildlife photographers, autofocus speed and accuracy can make or break a shot. Here, the GH3 again flexes its advanced capabilities.

The SP-600 UZ uses a contrast-detection AF with 143 focus points (multi-area). It offers some basic tracking but lacks face detection or continuous AF modes. The lens’s large zoom range trades off speed for versatility, and focus hunting can occasionally frustrate quick grab shots.

The GH3 features a contrast-detection AF system with 23 focus points supporting face detection and continuous autofocus (AF-C) with tracking. While it lacks phase-detection AF (common in modern mirrorless cameras), its Venus Engine VII processor enables fast and reliable AF for most uses.

• Continuous shooting speed: The SP-600 can shoot up to 10 fps (frames per second) in burst mode. The GH3 doubles that to an impressive 20 fps, excellent for sports, wildlife, or any fast action.
• AF live view: Both cameras support live view autofocus. The GH3’s hybrid touchscreen interface further enhances focusing flexibility.
• Face detection: Only available on the GH3.

In my tests, the GH3 nails focus quicker, especially in continuous tracking scenarios like runners or birds in flight. The SP-600 feels slower and less reliable for fast-moving subjects.

The Viewfinder and LCD Screen: Critical for Composing

Both cameras rely heavily on their rear LCDs and electronic viewfinders, but the quality and functionality greatly differ.

The Olympus SP-600 uses a fixed 2.7" LCD with a 230k dots resolution - not cutting-edge even at release, and it’s not touchscreen nor articulating. No EVF is included, so you rely on the screen for composition (less ideal in bright sunlight).

The GH3 boasts a superior 3" fully articulating OLED touchscreen with 614k dots resolution, providing deep contrast, vivid colors, and excellent viewing angles for shooting at odd perspectives. It also includes a high-res electronic viewfinder with 1,744k dots resolution, 100% coverage, and 0.67x magnification - a joy for precise manual focus and stable shooting.

The sharpness and responsiveness of the GH3’s screen make a noticeable difference in framing and menu navigation. The Olympus’ screen often feels cramped and less detailed.

Lens Ecosystem: Fixed Convenience vs. Interchangeable Flexibility

One huge factor is whether you want fixed lens simplicity or the versatility of interchangeable lenses.

The SP-600 UZ has a fixed 28-420mm (35mm equivalent) zoom lens with max aperture f/3.5-5.4. This covers a very broad focal length range - great for travel or casual shooting where lens changes are a hassle. It even focuses down to 1cm for close-up shots, a nice bonus.

The GH3 uses the Micro Four Thirds lens mount, giving you access to over 100 native lenses and countless third-party options ranging from wide-angle primes to supertelephoto zooms. This system is well supported and versatile for virtually every photography discipline, including:

• Fast prime lenses for portraits with creamy bokeh
• Macro lenses for detailed close-ups
• Professional telephoto zooms for wildlife and sports
• Compact pancake lenses for street and travel

This choice represents a critical tradeoff:

• SP-600: Convenience and simplicity, but limited optical quality (small sensor lens design limits sharpness and aperture)
• GH3: Requires investment in lenses, but provides great creative freedom and optical excellence

Battery Life and Storage: Endurance and Convenience

Battery life is a practical concern, especially for trips and long shoots.

The Olympus SP-600’s battery life is unspecified in official specs but compact superzooms typically last about 200-300 shots per charge.

The GH3 boasts an impressive battery life of about 540 shots per charge (CIPA standard), excellent for a mirrorless camera of its time.

The GH3 supports SD/SDHC/SDXC cards, giving greater storage flexibility and speed options. The SP-600 has one SD/SDHC slot but naturally supports smaller capacity cards due to age.

Video Capabilities: From Basic to Pro-Ready

Video quality is a huge consideration nowadays for both hobbyists and professionals.

The SP-600 UZ shoots 720p HD (1280 x 720) video at 24 fps. It uses H.264 compression but offers no microphone input or advanced video controls. Good for casual home videos but limited for serious filmmakers or videographers.

The GH3 is a game changer for its era, offering Full HD 1080p video at variable frame rates (60, 50, 30, 25, 24 fps). File formats include AVCHD and H.264, giving high-quality footage. Key pro features on the GH3 include:

• External microphone and headphone jacks for audio monitoring
• Focus peaking and zebra pattern for exposure control
• Time-lapse recording
• Articulating touchscreen assists creative framing during video

If video matters to you, the GH3 is firmly in another league.
