The door to the battery compartment is a big plus. If you film on Superview all the time, then the 8 isn't better than the 7. It's only on Hypersmooth High that the 8 distiguishes itself from the 7.
Well right off the bat, the damn thumb screw on my actual rig ends up being in the way of the door. i can fix that by just flipping the mount, and letting the camera ride a little lower (cant put camera right side up since the angle on a chest rig would suck balls then. and possibly show mine.) Minor gripe. Guess i could also use the mount adapter that has the mini ball head swivel deal built in and just rotate that to put the thumb screw on the other side. Either way, still worth it. =)
as for field of view, im not really married to any single option there, and my hero 7 has been sitting on wide for as long as i can remember. Even with the cropping involved in the increasing stabilization levels, i think i kinda like the view it provides more than native wide (or superview even.)
Managed to get a short ride in after work today and picked the rockiest trail segments I could think of for the test. Despite my eyeballs rattling in my skull on these bits, im impressed as hell with how the 8 smoothed it out.
pardon the ****-tastic exposure. never really shot in the light just before sunset (not for video anyway) and was less concerned with quality than testing function and stabilization.
Did a little nerd-checking comparing files between the 7 and 8 as well.
The Hero 7 Black supposedly pumps out 78mbit file bitrates in 4k/protune. Maybe that's only in 60fps? All my 4k30 footage seems to be 60mbit on the hero 7. that said, a 4gb video from that camera has 8 minutes and 52 seconds worth of footage in it. hevc of course.
The hero 8, also 4k30 for my footage, hit the newly increased 100mbit output almost exactly (100.158mbit actually) and the sae 4GB of recorded footage has a runtime of 5 minutes and 20 seconds. hevc as well.
Just something for folks to consider if storage is an issue =) Thankfully, fast/quality 128GB cards are dirt cheap these days, as are computer hard drives and cloud storage.
I look forward to some more testing in lighting im more familiar with to see if that 66% bitrate increase pays off.
