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
Noticeably better sharpness than standard K-5 II; Compact yet control-rich body packs in the features; Updated autofocus system focuses in near-darkness; Fully weather-sealed; Very good dynamic range; In-body image stabilization; Dual-axis level with horizon correction.
Prone to moire, aliasing, and false color artifacts; Can seem intimidating at first; Fewer autofocus points than competitors; Doesn't take advantage of high-speed UHS-I flash cards; Movie feature set is very dated and file sizes huge.
Very good image quality at low to moderately high ISOs; Blazing fast single-shot autofocus; Fast 9fps burst with RAW and JPEG files; Built-in Wi-Fi with NFC; Good build quality; Tilting EVF; Articulating touchscreen monitor; Bundled with Adobe Lightroom 5 software; Excellent value.
Dynamic range not as good as the best APS-C models; Slow buffer clearing even with fast UHS-I cards; Buffer depth with RAW files is underwhelming; Native lens selection is still fairly limited.
