Ease of Use:


  • Outstanding value! Beyond expectations
    Verified BuyerReviewed by TheEdge - March 25, 2019

    Been doing a lot of reviews of many of the new cameras. Wanted one that would provide excellent focus and 4k video. The 6400 was a lot less money than I was willing to spend, which allowed me to get more lenses and a gimbal and still spent less than many other brands or models. Such a great value. Once my wife and I started to take pictures and video, I found the camera went way beyond expectations for this price point. 10 frames per second of fast moving objects and found 95% perfect focus on what should have been in focus. If your willing to increase the iso in low light, even better percentage of in focus! And the higher iso looks really good.

  • Great Autofocus
    Verified BuyerReviewed by Phillexx - January 18, 2021

    Bought this to reduce the weight of my camera gear from a DSLR as I found I was carrying a compact camera around rather than my heavy gear, but as a consequence the quality and responsiveness was reduced. The A6400 has better autofocus than my DSLR, is as responsive and has the same if not slightly better quality (much more so than the compact I was using). The eye tracking is great and surprisingly sticky in that it will track like it is stuck on the eye or face or object. The exposure is highly accurate and I often do not need to dial in any compensation. All in all a remarkable camera in a small body that is suitable for most types of photography.

  • Great camera but...
    Verified BuyerReviewed by Anubis2490 - November 10, 2019

    Pros: - Excellent picture quality in 4k - Plenty of setting possibilities in 4k - Amazing autofocus even video mode - Light weight - Excellent picture quality in RAW Cons: - No tracking eye focus in video mode - No face detection if external monitor connected (Samsung Galaxy S10 plus via wifi) - No 60 fps or more in 4k - No IBIS - Poor battery life - Touch screen limitation - Power zoom speed not adjustable - Rolling shutter - Using DJI Ronin SC focus wheel for zoom: not smooth Walking with gimbal (DJI Ronin SC) the picture is shaking a little bit (other cameras, for example the Olympus Pen E-PL9 is not) - any solution (firmware update)? - The attached video has been made with Ronin SC, Sony 16-50 3.5-5.6 OSS lens, picture profile 10, no color grading, no warp stabilizer
