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
High quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.
Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.
Eliminated sensor dust-and-oil spot issue from D600; Great controls for amateur or pro; Comfortable ergonomics and weight; Excellent image quality and low-light performance; Very good dynamic range; Excellent battery life; Built-in lens correction.
Not drastically different from D600; Moire with certain subjects; Auto WB still too warm in incandescent light; Slow AF in live view mode; Aliasing in videos.
