Review Excerpt

  • 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.

  • Excellent still image quality for its class; Fantastic, highly-detailed video quality; Superior video recording chops with 4K video (both Cinema 4K and Ultra HD); Responsive all-around performer with great AF performance and burst shooting; Rolling shutter is minimal with 60p and 30p video; Splash- and dust-proof magnesium alloy body; Built-in Wi-Fi with NFC.

  • High ISO performance not as good as some APS-C models (IQ drops quickly past ISO 3200); Overall still image quality not significantly better than the GH3; Sluggish buffer clearing with RAW files; Rolling shutter noticeable on 4K video; Not as compact as most mirrorless cameras.
