So it seems like this problem isn't a figment of peoples imagination. I've been following these 7dii threads for months and have hears there are only 2 or 3 problems and the rest are user error or from not reading the manual. So either canon is trying to shut the customer up by saying there is a problem when there really isn't, or the problem exists and affects more than what the naysayers try to say on these threads. Just saying.
That was my problem. Mine worked so flawlessly as I mentioned, I thought I must be doing something wrong when I started missing shots on a consistent basis. I knew I hadn't changed anything except the firmware and I didn't really know anyone else who had a problem with the newest firmware.
I got a bit paranoid and bought a 1D IV to see if it was me. I was relieved to find out it wasn't me.... and a bit perturbed as well. I sold 3 lenses and my new Canon replacement 7D2 at reduced prices to pay for the 1D IV and the 16-35 f/4L I bought. It was right after Christmas so I priced things to move quickly. The purchasers both got a great deal.
That said, the 7D2 is a very fine camera. I don't think the problems are systemic. I think they are rare and random, based on the reading I've done. But when it's bad, it can be very bad. Because the AF is fairly complicated and there is a learning curve, people aren't sure if it's them or the camera when things are fuzzy/out of focus. I know I spent quite a bit of time early on reading about the AF system, took advice from a few people and was able to fine tune things for my shooting style. It takes some effort but isn't all that difficult if you work with it. Canon replaced my defective one, so they stood behind their product.
