Don't read that as a review, just first impressions. I enjoy using the Session and I should say that an action camera should be set and record, deal with framing later as 4k gives you some cropping flexibility. The Session does that brilliantly. The record button on the top is really all you need when you are out and about.Haven't seen such a positive yet negative review.
Never wanted a GoPro, but the Session 5 is basically the Hero 5 in small form factor. Of course it's going to be expensive, but I'm sure it's worth it.
Not sure it's worth the price as I think GoPro tend to over price. Comparing it to the Black to see if it's value for money wouldn't be right. The Black, even though cheaper than the 4 Black, is still too much money I think.
