5.0 megapixels (effective); 5x optical zoom/4x digital zoom; auto and manual focus; program and manual exposure ; JPEG and TIFF file format; ISO range 64-400; proprietary Lithium-Ion battery; movie mode with sound
The Pentax Optio 550 manages to cram a 5-megapixel sensor and a 5x optical zoom into body little bigger than a deck of cards. This long zoom sets the Optio 550 apart from other compact 5-megapixel cameras, most of which offer only 3- or 4x optical zoom. Offering an impressive suite of manual controls, and a durable metal body, this camera combines form and function remarkably well.
