1. First Impressions: Design, Size & Handling

When first holding these cameras, the form factor difference is immediately clear. The Olympus SP-590 UZ is a bridge camera designed to emulate an SLR-like grip and control feel but with an all-in-one fixed superzoom lens. In contrast, the Panasonic GX1 is a compact mirrorless body styled after traditional rangefinder cameras, optimized for portability and modularity.

• Olympus SP-590 UZ:
  • Bulkier at 116 x 84 x 81 mm, weighing 413 g.
  • Ergonomically designed with a substantial handgrip to handle its long 26-676mm equivalent zoom.
  • Fixed LCD: 2.7-inch fixed screen with modest 230k resolution.
• Panasonic GX1:
  • Smaller, sleeker body at 116 x 68 x 39 mm and lighter 318 g.
  • Minimalist rangefinder style designed for easy travel and one-handed use.
  • Larger, sharper 3" touchscreen with 460k resolution for better framing and menu navigation.

My take: For users prioritizing a lighter, more pocketable camera with modern controls, the GX1 is a clear winner. The SP-590, while heavier, feels sturdy and its fixed long zoom means you have everything built-in - great for superzoom fans.

2. Sensor and Image Quality: The Heart of the Camera

Sensor performance is paramount for image quality. Here, the cameras differ drastically:

The Panasonic GX1’s Four Thirds sensor is substantially larger than the SP-590’s tiny 1/2.3-inch CCD sensor embedded in a superzoom. This difference results in noticeably superior noise performance, dynamic range, and color fidelity on the GX1, making it the clear choice for quality-conscious photographers.

Personal testing notes: The SP-590 produces acceptable images in bright daylight but shows significant noise at ISO 800 and above, limiting low-light usability. The GX1, in contrast, maintains clean output up to ISO 1600–3200 and also delivers richer, more detailed RAW files due to its larger sensor and more advanced processing engine.

3. Autofocus Systems Under Real-World Conditions

AF speed and accuracy define a camera’s usability, especially if you capture fast action or wildlife.

The GX1’s 23-point AF system far outguns the SP-590's simpler contrast detection with fewer, less configurable points. Face detection and tracking on the GX1 make portraits and moving subjects easier to shoot with confidence.

Having tested both extensively, I found the SP-590’s AF noticeably slower, especially in low light or at telephoto zoom ranges. The GX1’s contrast detection with face and subject tracking delivers snappier, more reliable focus lock, handy for event and street photography.
