Longer stills battery life

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

Review Excerpt

Very good image quality; More consumer-friendly control setup than NEX-7 but more advanced (actual Mode dial) than step-down models; OLED EVF and 3-inch tilting LCD monitor provide viewfinder flexibility; Fast and decisive AF on stationary subjects, and good continuous AF on normal moving subjects; Full HD 1080p video recording at up to 60p.
Hybrid AF system speed and accuracy still lags somewhat behind higher-end DSLRs; Wi-Fi features still rudimentary (join the club); LCD is not a touchscreen; User interface foibles.
Read our Sony NEX-6 Review

Top-notch image quality; Spectacular detail from Pixel Shift Resolution; Better performance than K-3; Geotag images with no accessories; Great ergonomics in a compact body; Clever on-demand low-pass filtering; Broad sensitivity range; Large and bright viewfinder for an APS-C camera; Dual card slots
No built-in flash strobe; No wireless flash support out of the box; AstroTracer function can be finicky; AE Lock button is poorly located; Below-average battery life for a prosumer DSLR; Requires a different battery grip accessory than its predecessors
