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
Incredibly small body for a fully-featured, full-frame camera; Resolution that rivals a medium-format camera; Excellent image quality even at very high sensitivities; Decent performance bearing in mind its extremely high resolution; Accepts existing Alpha-mount and E-mount lenses, and can optionally crop to APS-C image circle.
Extreme resolution makes focus and lens quality critical; Modest performance; Loud shutter; Lacks hybrid autofocus of the A7; Mediocre battery life when using electronic viewfinder; Slow X-sync; Limited selection of native Sony FE lenses.
Very good image quality; Great high ISO performance for its class; Very good optical performance from the kit lens; Decent battery life; Very good value for the money.
No built-in EVF; Slower than average full autofocus shutter lag in testing; Sluggish continuous AF for stills & video; Mediocre burst speeds; Limited dynamic range with JPEGs; No remote control with Wi-Fi.
