Review Excerpt

  • Side-mounted tilt / swivel LCD screen; same sensor and processing as the Nikon D7000; good speed and battery life; in-camera HDR and filter effects; Full HD video capture with aperture control; audio levels control and external microphone jack.

  • AF-S lens mount doesn't offer autofocus with screw-drive lenses; popup flash isn't the greatest; no built-in wireless flash control; HDR function doesn't microalign source images.

  • Excellent image quality similar to Rebel T4i, T5i and SL1 DSLRs, with 18-megapixel APS-C-type sensor delivering considerable resolution for a mirrorless camera; Solid build and sleek design; Bright, high-resolution 3-inch LCD touchscreen monitor; Full 1080p HD video recording that's virtually silent with an STM lens.

  • Barely acceptable autofocus speed still lags far behind most mirrorless cameras despite firmware update fix; Limited physical controls and buttons, including no Program, Priority, or Manual on Mode dial; Lacks built-in flash or electronic viewfinder option; Only two compact EF-M mount lenses currently available.
