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.
You can learn more at our glossary entry.

Cameras 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.

Cameras with longer battery life can take more photos before exhausting their batteries.
Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
Very good image quality with high-resolution files; Excellent high ISO performance with RAW files; Very good dynamic range; Fast AF performance; Compact design with good build quality; Better ergonomics than predecessor; 4K video recording.
High ISO noise reduction too strong; AF struggles in low-light; Buffer depth is shallow with RAW files; No option for EVF; No built-in flash (external one included); 4K Video is cropped with narrower FOV.
