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
Excellent build and comfortable handling; Bright, roomy viewfinder and articulated LCD; Great image quality; Good performance for the class; In-camera stabilization, GPS and Wi-Fi; Incredibly feature-rich design.
Bulkier than APS-C DSLRs; Top ISOs are for the spec sheet, not the real world; JPEGs are a bit punchy by default; Slow startup; Below-average battery life; Only a relatively modest update to the K-1.
Comfortable ergonomics and solid build; Versatile EVF and tilt-swivel, touch-screen LCD; Good image quality; Great performance for its class; New C-RAW format saves on raw file size; 4K video is an M-series first.
Somewhat limited dynamic range; JPEGs a little soft at base ISO, and more so at higher ISOs; Warm white balance under incandescent light; Poor battery life; Raw buffer is still shallow (but C-RAW helps).
