Review Excerpt

Pocket-friendly design; Popup electronic viewfinder; Bright lens across the zoom range; Great performance with very fast autofocus; Very high resolution gives lots of detail in good light; High ISO noise levels much better than most pocket camera rivals; Wi-Fi wireless networking
Feels a little unbalanced without an accessory grip; Not as much telephoto reach as its siblings; Noise processing is heavier-handed than in earlier models; Quite pricey for a fixed-lens camera

Impressive image quality; Sleek design; 4K video recording; Good overall performance; Tilting touchscreen; Enjoyable user experience.
No EVF; No hot shoe, Short 4K clip limit; MicroSD card slot, Poor battery life.
