Purchased this camera in March 2017 and during a photoshoot in August the AF system stopped working. When using either Back Button Focus or Shutter button to focus the camera struggled to lock in AF and when it did lock in to focus the AF point was obviously blurry, upon depressing the shutter button the camera completely shut off. I was using a Tamron 24-70mm and I read in an online article after the fact that this 80D is a little slower to focus using third party lenses such as my Tamron. Also the reviewer that wrote the article stated that using Live View mode with a Tamron 24-70mm lens caused the camera to shut off, much like what happened to me. I talked to Canon about the issue and they had me send it off. I am still waiting to hear back. I wish I had known about the issue of compatability with third party lenses before I purchased this camera. I will try to update as to how Canon resolves my issue, its a bummer being without my camera in the meantime.
