It records stuff!
I've purchased my laptop, iPad Pro 11" (2G, Cellular), the fancy iPad Pro cover/keyboard, my laptop, and this GoPro, as open-box or refurbished. Not a single item has been defective in the slightest way and I saved hundreds of dollars so far. No reason to pay full-price for these items.Also, before settling on my current iPad Pro 11", I had other versions, all refurbished, all were just fine (no cosmetic damages or malfunctions), and again, saved a lot of money. I was able to return the items when no longer needed at no cost to me.So don't be a sucker- try buying refurbished items first and if something is wrong, Amazon and other stores have generous return policies.Anyhow, the biggest gripe I have with GoPro is their crappy desktop software. GPS signal reception by these things is incredibly weak...although when using 3rd-party apps, I can see GPS data was encoded in the video, but the GoPro software won't ever display it.The Hero 8 is much improved over the Hero 7 and earlier, but the Hero 9 isn't much more than a, "My male part is bigger than yours". Can't watch 5K video in 5K if your GPU and display don't support it, so what's the point? (yes, I said 5K, because that's what the 9 advertises, IIRC) Also, the larger the resolution, the more space you'll need on your SD card.Anyhow, that's my rant. Go away now.

A good purchase
Excellent night visionCamera works great! The connection is a little slow at longer distances, but it doesn't affect usability. Setup should be pretty easy for the experienced, I was using it for the first time and thankfully my husband figured it out quickly.

Q
Is the K&F Concept adapter for Pentax PK K mount to Sony NEX e-mount compatible with the Sony A6000? Does a P-KA mount adapter exist?
A
Yes it should work with the sony a6000. As long as the ka lens has an aperture ring on the lens and is not solely dependent on receiving aperture control from the body, this adapter should work fine with ka lenses. To my knowledge, there are no sony e mount to k mount adapters with electronic coupling so no lens control through the body (meaning aperture and focus are fully manual).
