Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.
Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

Outstanding design and build; Exceptionally sharp 28-70mm equivalent zoom lens; Very good still image quality with accurate and realistic colors; Fairly speedy and accurate autofocusing.
Expensive, especially for a fixed-lens compact; Relatively slow f/3.5-6.4 lens; Below average video functionality and quality; Not at all pocketable, about as big and heavy as a mirrorless camera with a moderate zoom lens attached.
Shooting with a wide prime helps you see new shots; Good performance and fast autofocus; Excellent sharp, bright lens; Very customizable; In-camera Wi-Fi works with more than just Android and iOS; Supports Pentax wireless flash strobes
Fixed, wide prime lens isn't for everyone; Cramped controls; Burst capture is slower for JPEGs; Tends too warm under incandescent lighting; Wi-Fi app is poor, and web browser control has cluttered interface
