Composing your shots requires responsive displays and reliable viewfinders. The SL30 features a modest 2.5-inch fixed LCD with 230k dots, while the A77 shines with a 3-inch fully articulated LCD boasting 921k dots and an advanced electronic viewfinder (EVF) matching 100% frame coverage.

Sony A77’s EVF and Articulating Screen

• The vibrant EVF with 2.36 million dots gives you a DSLR-like experience with eye-level composition and real-time exposure adjustments.
• Articulating touchscreen (non-touch in this case but fully adjustable) adds flexibility for creative angles like low or high shots.
• Focus peaking and live histogram assist in manual focus precision and exposure monitoring.

Samsung SL30’s Display

• Fixed, small screen with limited resolution reduces the ability to review images critically.
