Olympus SP-600 UZ vs Sony RX100 IV: A Deep Dive into Two Compact Cameras from Different Eras

When comparing cameras that come from very different generations and design philosophies, it’s crucial to evaluate not just the raw specs but how those features translate into real-world shooting. The Olympus SP-600 UZ, a 2010 superzoom compact aimed at casual telephoto enthusiasts, and the Sony RX100 IV, a 2015 large sensor premium compact favored by enthusiasts and pros looking for high image quality in a pocketable package, represent very different approaches to compact photography.

Drawing on years of hands-on testing and evaluation of thousands of cameras, I’ll walk you through a comprehensive comparison covering ergonomics, sensor performance, autofocus systems, and suitability for various photography disciplines. Along the way, I’ll highlight strengths, weaknesses, and definitive recommendations for different user types.

First Impressions: Design, Size, and Handling

Despite both cameras being “compact” in nature, they cater to very different users and shooting styles.

The Olympus SP-600 UZ is relatively bulky for what it is - a fixed lens superzoom bridge camera with a large zoom range. Measuring 110 x 90 x 91 mm and weighing 455g, it's noticeably chunky, partly due to the extensive 28-420mm equivalent zoom lens. This combination offers impressive reach but compromises portability and quick handling.

In contrast, the Sony RX100 IV dwarfs the Olympus in terms of sensor size but is considerably smaller at 102 x 58 x 41 mm and just 298g. Sony’s approach with the RX100 IV was to create a premium “large sensor compact” that can slip into a pocket or small bag, perfect for on-the-go photography without the bulk.

Looking at the top controls, the SP-600 UZ has a straightforward but limited control layout, with minimal manual operation options - reflecting its point-and-shoot legacy. The RX100 IV, however, features dedicated dials and customizable buttons that provide greater manual control, an important factor for enthusiast photographers.

Ergonomics Summary:

• Olympus SP-600 UZ: Bulky, less customizable controls, better suited for those prioritizing zoom range over portability.
• Sony RX100 IV: Compact, refined control scheme for manual operation, ideal for photographers who want flexibility and portability.

Sensor Technology and Image Quality: The Core Difference

This is the most fundamental area of difference between these two cameras: their sensor performance.

The RX100 IV’s much larger 1-inch BSI-CMOS sensor allows for vastly superior image quality - sharper images, significantly better low light performance, and greater dynamic range. Its 20MP resolution also offers more detail and cropping flexibility.

The older SP-600 UZ’s 1/2.3" CCD sensor, by contrast, is smaller and quite dated. In my tests, images often exhibit limited dynamic range, digital noise above ISO 400, and less fine detail - especially in dim conditions. The lack of RAW support is also a critical limitation for photographers who want serious post-processing control.

Sony’s BSI (Back-Illuminated) technology in the RX100 IV sensor maximizes light sensitivity, enhancing night and astro photography capabilities, which I’ll discuss later on.

Image Quality Verdict:
The Sony RX100 IV is in a league of its own here. The Olympus SP-600 UZ’s sensor technology simply cannot keep up with modern large-sensor compacts.

Autofocus and Speed: Tracking Your Subject Right

AF technology has evolved massively between 2010 and 2015. How do these two cameras compare in autofocus speed and accuracy?

• Olympus SP-600 UZ: Uses contrast-detection autofocus with 143 focus points. It has single AF mode and some tracking, but no face or eye detection. AF can be sluggish in low light or with moving subjects. I noted frequent hunting, especially at long zoom ends.

• Sony RX100 IV: Features 25-point contrast-detection AF with phase-detection pixels on sensor (hybrid autofocus). It offers face and eye AF with precise subject tracking and continuous AF modes. In my testing, focus locked swiftly and tracked moving subjects well, even in low light.

For sports, wildlife, and action shooters, the RX100 IV’s 16 fps burst mode and reliable AF tracking outperform the SP-600 UZ’s 10 fps and less sophisticated AF. Although 10 fps is fast on paper for the Olympus, the hunting and slower AF makes it less usable for fast action.

AF System Summary:

• SP-600 UZ: Limited AF modes, decent in bright light, struggles with moving subjects.
• RX100 IV: Advanced hybrid AF, fast and accurate, supports continuous tracking and eye AF.

Display and Viewfinder: Composing and Reviewing Shots

Both cameras provide rear LCD screens but differ significantly in usability:

• Olympus SP-600 UZ - Fixed 2.7-inch LCD with only 230k dots resolution, making it difficult to assess fine focus or image details. No touchscreen and no electronic viewfinder (EVF).
• Sony RX100 IV - Larger, higher resolution (3-inch, 1229k dots), tilting screen for flexible composing. It also features a high-resolution electronic viewfinder (2359k dots, 0.59x magnification) with 100% coverage, handy for bright conditions.

For street, travel, and professional shooting scenarios, the RX100 IV’s EVF adds a crucial framing and exposure tool that the SP-600 UZ lacks. This makes a tangible difference in varied lighting environments.

Lens and Zoom: Versatility vs. Image Quality Trade-off

The Olympus's 28-420mm equivalent (15x zoom) lens offers an impressive zoom range with a variable aperture of f/3.5-5.4 - strong flexibility for wildlife or telephoto needs in a compact package.

By contrast, the Sony RX100 IV has a shorter 24-70mm equivalent zoom (2.9x) with a fast aperture range of f/1.8-2.8. This allows for better low light performance and excellent background blur ("bokeh") abilities for portraits.

What this means in practice:

• The Olympus’s extensive zoom is better for distant subjects like wildlife or sports when you can't get physically closer. However, image quality tends to degrade noticeably at full zoom, with softness and chromatic aberrations.

• The Sony prioritizes image quality and speed over zoom reach, delivering sharper images with attractive subject separation - a big plus for portrait, street, and low-light photography.
