I've been filming my daughter's soccer games with a GoPro Hero 5 mounted to a 12' crane jib. I'm filming in 1080p 60fps Narrow FOV and the video, especially at farther distances, looks blurry and out of focus to me. I've filmed in both auto and with Protune turned on with various setting changes but I'm still disappointed with how it turns out. Objects that are fairly close to the camera look pretty good but everything beyond around 12ft seems blurry, out of focus, not sharp. I'm hoping someone can take a look at the youtube videos posted below and tell me if that's how they would expect the video to look at 1080p 60 Narrow. Any suggestions appreciated. Thanks!

I feel the same when I use my camera in ways the close up on a FF lens I know will be Blurry and everything in the center will be focused and while the grub in hte background is vlurry. My attention is not the background it's what I am aiming for and that is what matters. on an action camera Infinity is not going to be perfect. but ithas to look decent.

As mentioned above it might also be related to too much expectations from a fixed fisheye lens.
Doing 60 FPS which might invoke pixel-binning on sensor to accomodate the higher FPS as well as narrow FOV which crops out much of the sensor area will probably alleviate the quality further.
I live in PAL land so I do most filming in 25 FPS, but will give 50/60 FPS a go as well to see if there is a noticeable qulity reduction.
BTW: If you try the HD 240 FPS mode you will see the full effect of on sensor pixel binning.

Mic Bergsma has done a 24-120 FPS test on youtube.
Apparently 60 fps is also clean, artifacts creeps in at 90, 120 and 240 FPS modes (240 FPS was included later in Hero4 firmware so not included in this test.
Seems like best advice is to experiment with FOV and perhaps the sharpness setting.
I also recommend using an ND filter to adjust the shutter down in (bright) daylight scenes. I use the PolarPro series myself. This makes the image more professional looking.
