Longer stills battery life

Cameras with longer battery life can take more photos before exhausting their batteries.

More sensor area. Bigger is (generally) better.
Tiltable Screen
Tiltable vs Fixed

Higher effective ISO

Higher effective ISO

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.

4,505 vs 3,279 iso
Take photos in low light with less noise
More dynamic range

More dynamic range

Cameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.

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.

Review Excerpt

Same sensor and processor as professional D4; Great image quality; Arguably the best available-light shooter in its class; Handsome, retro styling; Weather-sealed design; Big, clear full-frame viewfinder; Excellent battery life
Expensive; Bulky, yet handgrip is quite modest; Some controls are clumsy; Plastic body panels don't gel with retro aesthetic; Autofocus isn't in the same league as image quality; No AF assist lamp; No movie capture; No portrait grip; Single card slot
Read our Nikon Df Review

Phenomenal resolution and detail; Great high ISO performance; Rugged, weather-sealed body; Huge, bright viewfinder; Fast autofocus works well in low light; Swift performance for a medium-format camera; Good battery life; Shoots Full HD video
Quite bulky compared to an APS-C or full-frame DSLR; Autofocus points clustered near center of frame; Most lenses aren't weather-sealed or optimized for digital; Prone to aliasing artifacts (but so are most high-end cameras these days); Attracts a lot of attention from passers-by
