Hmm. I cannot stand their style, but it was a surprisingly informative video, and It led me on to the video they commented on, and then to a guy talking about audio.
As I have been buying audio gear recently, which has much in common with camera gear. it is harder than we think to get unbiased information. I was quite successful in my purchases, thanks to a mix of reviews and most of all user comments on forums.
User reviews and comments often pick up defects and downsides that a reviewer will never pick up. I recently came across a comment about a €8000 lens, where the lens bayonet mount wears out quickly, thanks to bad material choices. When i was replacing my worn out EM5, a forum thread illustrated the dramatic weakness of the tripod mount in my intended choice.
Editorial reviews need to be considered with a pinch of salt sometimes (It is actually fairly easy to sus a reviewer that has had some sort of kickback), Fanboyism often plagues gear forums. With camera gear I always like to try a camera or lens out at my dealers before buying. But buying new gear is always a lottery, you might miss a camera defect, or the lens you buy might be a bad copy.
