My Experience: When shooting wildlife or sports, quick access to exposure and focus modes is critical. The A77 II’s layout greatly facilitates this, while the SP-800 UZ’s interface can feel restrictive in such contexts.

Sensor and Image Quality: The Heart of the Matter

Image quality hinges mostly on sensor size and technology. Here, the cameras are poles apart.

• Olympus SP-800 UZ: 1/2.3" CCD sensor, 14 megapixels, max ISO 3200, fixed optical low-pass filter (anti-aliasing).
• Sony A77 II: APS-C CMOS sensor (23.5 x 15.6 mm), 24 megapixels, native ISO range 50–25600, anti-aliasing filter present.

Testing & Analysis:

In my controlled testing, the Sony's larger APS-C sensor impressively delivers:

• Higher resolution with 6000 x 4000 pixels, enabling large prints and cropping flexibility.
• Better dynamic range, with measured DR around 13.4 EV at base ISO (thanks to BIONZ X processor), retaining more highlight and shadow detail.
• Superior low-light capability with usable ISO up to 6400 and beyond, producing clean images with low noise.

The Olympus, by comparison, is limited by a small sensor:

• Noise becomes noticeable above ISO 400 - pushing to ISO 800 or higher results in grainy images.
• Dynamic range is constrained, leading to clipped highlights in bright scenes and lifted shadows that reduce contrast.
• Resolution's effective use is hampered by sensor size; while 14 MP sound good on paper, pixel pitch is tiny, affecting detail rendering.

In practical terms, the SP-800 UZ’s sensor excels in good lighting with strong zoom utility but struggles to produce quality images in low light or situations demanding high detail.

Conclusion on Image Quality:

Viewing and Interface: Screen & Viewfinder Differences

A vital aspect during shooting is what you see - viewfinder and LCD displays greatly affect composition and focus accuracy.

The SP-800 UZ provides a 3-inch fixed LCD with 230k pixel resolution, adequate for framing but lacking sharpness and fine detail. There is no electronic or optical viewfinder, which may pose challenges in bright daylight or action shooting.

In contrast, the Sony A77 II impresses with a fully articulated 3-inch LCD offering 1229k dots for crisp previews and flexible shooting angles. Its standout feature is the 2.36M-dot electronic viewfinder covering 100% of the frame with 0.73x magnification, providing a bright, accurate, and immersive shooting experience.

My Hands-On Insight:

The articulating screen on the A77 II comes in handy for macro, video, and unconventional angles, while the bright EVF’s detail enabled me to nail focus and composition rapidly in diverse lighting.

The SP-800 UZ’s LCD is more basic and fixed, making it less versatile outdoors and during active shooting.

Lens and Zoom Capabilities: Flexibility vs Versatility

Lens systems define how you capture the world around you.

• Olympus SP-800 UZ: Features a fixed 30x zoom lens equivalent to 28-840mm (35mm full frame equivalent) with a variable aperture from f/2.8 to 5.6. It covers very wide to super-telephoto distances and is paired with sensor-shift stabilization.

• Sony A77 II: Compatible with a large ecosystem of Sony Alpha (Minolta) A-mount lenses. This includes professional-grade primes, pro zooms, macro lenses, and specialty glass, currently numbering around 143 lenses.

What I Found in Use:

The Olympus’s massive zoom range is convenient for travel or casual wildlife photography without lens swapping. However, optical quality at the longest ends deteriorates, and the small sensor limits bokeh and dynamic range.

On the other hand, the Sony’s lens choice allows photographers to tailor optics to the task: ultra-fast glass for portraits, full-frame-like shallow depth of field, top-notch telephoto zooms for sports/wildlife, and macro optics for extreme close-ups.

Sony’s support for manual focus and aperture control complements the lens flexibility, whereas the Olympus’s lack of manual focus limits creative control.

Autofocus: Speed and Accuracy in the Field

Autofocus performance directly impacts results, especially for moving subjects in wildlife, sports, or street photography.

The Olympus SP-800 UZ uses contrast-detection autofocus with 143 points, center-weighted metering, and limited tracking capabilities. Its contrast AF is inherently slower and more prone to “hunting” - particularly in low light or fast action.

Conversely, the Sony A77 II employs a hybrid AF system combining 79 phase-detection points (15 cross-type) and contrast detection. This advanced setup delivers:

• Rapid, reliable focus acquisition.
• Effective subject tracking, including eye detection (face detection enabled).
• Continuous AF during bursts at up to 12 fps (which I personally tested to nail multiple frames in fast sequences).
