  • Total Game Changer
    Reviewed by Kujav98 - March 12, 2018

    As a sports photographer I was extremely hesitant to make the move away from Nikon, but after 2 weeks with the Sony A9, I'm sold! Paired with the Sony GM 70-200 f/2.8, it's a total game changer for sports photography with the ability to comfortably shoot 10,000 ISO, tilt screen LCD, 20fps and a nearly silent shutter. Shooting state championships this past weekend, I was surrounded by Nikon and Canon shooters and was the only Sony there, but had lots of people asking me about it! On Saturday I shot intermittently for 12 hrs for a total of 2168 images, no grip and still had 18% battery life left on my FIRST battery at the end of the night!

  • Shocked
    Verified BuyerReviewed by jay19945 - August 4, 2017

    I'll start by saying I've been a professional wedding photographer for 17years. I've shot Nikon for the vast majority of that time.(short time with canon). I can honestly say this is the best camera system I have ever had the pleasure to shoot with. I was expecting a couple shining points to stick out to me but after shooting 6 weddings with the gear I can't find an area where I am less than thrilled. Focus system is amazing, low light..amazing. Coming from the d5 I was a bit nervous about stepping into a small frame camera but it feels great in the hand even with the 70-200 2.8. For me it was a great change and would do it again without question.

  • NO BLACK OUT SPEED!!!
    Reviewed by Gabe Rogel - September 11, 2017

    As a Sony Artisan of Imagery and adventure sport photographer, I have been waiting patiently for this camera to be released. I was in need of a faster camera... one that could shoot more frames per second. Well, Sony delivered! Not only am I blown away by the 20 frames-per-second RAW capability with almost no buffer, but the fact the camera will do this with NO shutter black out, is unbelievable!!! In other words, as you're shooting stills and looking through the viewfinder, it almost looks as though you're shooting video... a continuous image. This is of course extremely helpful for tracking fast-moving subjects.
