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
Phenomenal detail and "depth" at low ISOs; Extremely high resolution; Incredible image quality for the price and size (at low ISOs); Fast x-sync speeds; Unique design is unconventional but comfortable and balanced.
Poor high ISO performance; Very sluggish buffer clearing; Poor low-light AF; No built-in flash; Very limited third-party RAW file support; Bundled Sigma Photo Pro RAW software is slow and buggy.
Excellent image quality from both JPEGs and RAW files; Superb high ISO performance; Very fast hybrid AF; Robust weather sealing; Dual UHS-II card slots; 4K video.
Precise manual focus is tricky with fly-by-wire focusing; Battery life is only decent; Video quality still not on par with competing cameras.
