The second problem is that many video 'reviews' on the photographic internet are about the professional attributes of the gear written by non professionals. Just what experience do they have? Some like Phillip Bloom have actually worked for film and television companies. But as to the rest, I can find no information as to what gives them the justification to give opinions. Now I'm far from being any kind of video expert, but I suspect that I have had more paying video/film gigs than the majority of those who pontificate about hybrid cameras. Years ago I shot a lot of 16mm film for a company that produced TV advertising and more recently I've done work for educational bodies, including DVD teaching materials and events, in school and out and trade shows. And yes I got paid for all of it, so I don't need to beg on the internet.
My video needs have always been simple. Nice looking footage obtained in the easiest way possible. The above video was shot on my Leica Q2. All hand held, using the Q2's IS and finished off in iMovie. It was easy and simple to shoot and edit and I think that the result is pretty good. The Q2 produces great looking 4K footage that converts really well to B/W. Now I'm never going to shooting a movie or anything for TV. I do put the separate clips on one of my library websites, but that's it. Like the vast majority of video users my output is designed for the internet. And in fact that's what a lot of clients want these days. They probably get better returns from the internet, rather than television advertising (which is seriously expensive), anyway.
Basically there are a lot of cameras out there that will do most required video work perfectly well. And some things just aren't required in the professional video world either. Sound is always recorded separately, for better control. So a camera lacking microphone and/or headphone ports isn't always a problem. It is also worth remembering that the majority of feature films, shot on digital, are not shot in 4K. Now maybe in the future they might be, but that will increase all kinds of things, cost, weight, size, time etc. and all the movie theatres and TV's out there will have to change as well. Plus I don't know about you but every time I watch something on a 4K TV I start to get a headache. And even for the internet you have to have fast broadband to watch 4K anyway.
So next time you see someone waffling on about video specifications, firstly check to see what 'qualifications' that person has and secondly check out their sample videos. Because some of the samples I've seen, including vlogger posts, are embarrassingly bad. Just like with still photographs it's not the gear that you use, but what you produce that's the important thing. But then video nerds are unfortunately as bad as stills nerds. Gear over aesthetics every time.
