Reviewing shots and composing without an optical viewfinder requires a solid rear display.

The Olympus’s fixed 2.7-inch LCD with 230k-dot resolution is serviceable but uninspiring by modern standards. The lack of touch sensitivity or articulating mechanism limits flexibility, making it challenging to shoot from unconventional angles or preview fine details.

Meanwhile, the Sony A77’s 3-inch fully articulated display with nearly 1 million dots offers remarkable clarity and viewing angle freedom. While not touch-enabled, the combination of a high-res rear screen with an ultra-sharp electronic viewfinder caters well to photographers who compose in bright outdoor situations or prefer eye-level shooting.

For photographers who rely heavily on LCD feedback - travel shooters, vloggers, or street photographers - the Sony’s screen is far superior, enhancing usability and composition accuracy.

Autofocus System: Speed and Accuracy Across Genres

Autofocus (AF) can make or break your shooting experience, particularly in dynamic scenarios.

The Olympus SP-600 UZ employs contrast-detection AF with 143 focus points, which sounds generous but lacks phase detection, limiting continuous autofocus ability. In practice, this translates to decent performance for static subjects and casual use but sluggishness and hunting under low light. Its manual focus aids precision but is not ideal for fast-action scenarios.

The Sony A77 uses a hybrid AF system including 19 phase-detection points (11 cross-type), enabling swift and accurate focus acquisition. It supports continuous AF (AF-C), face detection, and multi-area AF - boosting reliability and tracking for wildlife, sports, and portraiture. Notably, eye detection autofocus is also functional, streamlining portrait workflow.

During field tests, the A77 consistently outpaced the Olympus in locking focus on moving subjects, especially under variable lighting. This makes the Sony a natural choice for sports and wildlife shooters, while Olympus suits static or landscape scenes better.

In the Field: Portrait Photography Performance

Portrait shooting demands natural skin tones, pleasing bokeh (background blur), and sharp eye focus.

The Olympus SP-600 UZ’s small sensor results in deeper depth of field at equivalent apertures, reducing the ability to isolate subjects creatively. The lens’s max aperture of f/3.5-5.4 yields limited bokeh control, and the weaker AF system lacks dedicated eye detection. Nonetheless, in good light, skin tones are passable for casual social use.

The Sony A77’s larger APS-C sensor coupled with fast lenses on the Sony Alpha mount allows exquisite background separation and subtle skin tone gradation. Face and eye detection AF streamline capturing crisp portraits, and RAW support facilitates nuanced post-processing. The A77's built-in sensor stabilization further assists in handheld portraiture with slower shutter speeds.

Overall, for serious portraitists, the A77 is vastly superior, while the Olympus meets basic Instagram or snapshot needs.

Landscape Photography: Dynamic Range and Resolution

Landscape photography benefits greatly from high resolution and expansive dynamic range to capture shadows and highlights evenly.

The Olympus’s 12 MP small sensor, combined with a moderate zoom, delivers images acceptable for web sharing and casual prints. However, limited dynamic range makes handling harsh sunlit scenes tricky, often necessitating HDR stacking or filters.

The Sony A77’s 24 MP APS-C sensor produces ample resolution for large prints and cropping flexibility. Its 13 stops of dynamic range ensure greater detail retention in high contrast scenes - whether sunrises, forests, or cityscapes. Weather sealing and robust body design also mean the Sony can handle rugged environments better.

Consequently, landscape photographers will find the A77 a distinctly more capable tool, especially when paired with quality wide-angle glass.

Wildlife and Sports Photography: Burst Rates and Tracking
