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.

  • Class-leading resolution; Excellent dynamic range; Very good high ISO performance; Very fast AF and burst shooting; Durable weather-sealed body; Improved ergonomics; Touchscreen; Dual card slots; 4K video.

  • Live view/video mode still uses sluggish contrast-detect AF; Viewfinder only tests at ~98% coverage; No 4K at 60p; 30-minute video clip limit; Focus peaking not supported with 4K.
