Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)
More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

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.

GR II test data on DxO Mark P7800 test data on DxO MarkCameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.
Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

GR II test data on DxO Mark P7800 test data on DxO MarkExcellent image quality for a 1/1.7" sensor; Versatile 28-200mm eq. lens with fast f/2-4 max aperture; Built-in EVF; Fully articulating LCD; Generous set of physical controls; Built-in flash with wireless support; Standard dedicated hot shoe; Full HD and slo-mo movies.
Slow cycle times and buffer clearing with RAW files; Shallow burst mode buffer; Mediocre autofocus speed and shutter lag; Sluggish UI at times; Slow to switch to movie mode; Optical zoom not supported during movie recording when using manual exposure modes; No built-in Wi-Fi.
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
