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.

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.

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 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).
Stylish "retro modern" design in two color schemes; attractive 3.3-inch AMOLED tilting touchscreen; new APS-C CMOS sensor with on-chip phase detection AF; better image quality, particularly in low light at high ISOs; faster all-around performance; improved Wi-Fi connectivity.
Camera feels more plasticky than expected when you pick it up; slower shot-to-speeds compared to rivals; poor buffer depth with raw files; aggressive anti-noise processing destroys detail in high ISO shots; display smudges easily and is rather dim; no EVF support.
