Longer stills battery life

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

Review Excerpt

Excellent high ISO performance, one of the best APS-C sensors yet; 6.5 fps burst mode has very good buffer depths; Weather, dust, and cold resistant; In-body Shake Reduction corrects not only horizontal / vertical, but also rotational motion.
Default saturation and contrast a bit high; Auto white balance too warm in tungsten light; Fewer AF points than main competitors; Only a single card slot, and no UHS-I card support (slow buffer clearing).
Read our Pentax K-5 Full Review

20MP sensor; Better per-pixel sharpness; Very good, slightly improved dynamic range and high ISOs; Stellar 4K video up to 60p with no crop; 6K Photo; Dual UHS-II SD slots; Good battery life for its class.
Buffer is deep, but slow to clear; Expensive; Menus still confusing; No optical low-pass filter means greater risk of moire; No built-in flash.
