Review Excerpt

High-quality constant aperture 10.7x zoom lens with excellent performance; Very affordable for what it delivers; Ergonomically sound with a solid, professional feel; Highly customizable; Fast overall performance; Built-in EVF and tilting touchscreen LCD; Automatic lens cap.
Smaller sensor size than 1-inch and Micro Four Thirds models mean far lower image quality as ISO tops 800; 28mm eq. is not as wide as some competitors and not overly suited for landscape photography.
