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
Great image quality for a tiny camera; Excellent high ISO for its class; Built-in EVF; Built-in hot-shoe; Improved ergonomics; Improved image quality for long exposures; Improved burst rate with hybrid shutter; 1080/60p video.
Slightly bigger than GM1 (but not by much); No built-in flash; Shallow buffers with RAW files; Dynamic range not quite as good as some competing models; Below average battery life.
Enthusiast-oriented compact camera body; Good image quality in most situations; Impressive Dual Pixel CMOS AF; Very good overall performance.
Dynamic range and high ISO image quality aren't quite up to par with some of its competition; No 4K video recording; Video features in general are underwhelming; Native EF-M lens selection is limited.
