Enjoy your 7D2!
I went out hiking this weekend, shooting some fall foliage with my T6i and 17-55/2.8. Most of my photos are severely front focused. I was shooting with a B&W CPL. I have noticed that the AF accuracy goes way down when the CPL is on. When I got home I noticed some big smudges on the filter. My theory now is that any smudges, condensation, or anything like that throws off the T6i AF. It seems that the camera drives the lens to minimum focus distance, gets a focus confirmation somehow, and then goes ahead with the exposure.
I wish focus confirmation had a real check for focus. I would prefer focus hunting over instantaneously shooting a photo out of focus.
