SIMPLE.He wants to buy it cuz he likes the old look of like vx's I believe as well as the ability to servo zoom. Just because you seem to have the biggest hard on EVER for gopros (as I've seen from your other posts in M&a) doesn't mean everyone else has to love them. Personally I hate gopros because it has terrible auto exposure and poor picture quality. Unless u have time to edit the shit out of it like Kyle Decker, you can always tell gopro videos apart from dslr video. You can't seriously tell me you can't tell the difference between a Gavin Rudy edit and a 12 year old gopro edit.
How do I in any way have a hard on for GoPro's? I recommend them to people where it seems appropriate. Are they the best camera of all time? Of course not. They have limitations, but there are also a huge list of advantages to them. I wasn't even trying to sell him one. I simply asked if he considered the new $130 GoPro. He wanted it to be so that so "any one can operate it and i dont really have to care about it."
That's the best part about the camera, anyone can use it, and they don't break. Sure you have only one focal length, sure there isn't a screen you can see, there's no servo zoom; but at the same time you gain a ton of other features that aren't present in $100-200 cameras. You get full HD, small form factor, relatively good optics, waterproof, extremely durable, records to sd cards, etc.
I'm not sure why you hate GoPro's either. There isn't really any reason to specifically hate the camera. The auto exposure isn't terrible by any means. In what ways is it terrible from your point of view? And ot say that it has poor picture quality is ridiculous. The new Hero4 shoots 4k at 30fps, nothing compares to that for $500.
Your point about being able to tell GoPro videos apart from DSLR's is irrelevant too. Gavin Rudy puts a ton of hours into making an edit, and he, to an extent, knows what he is doing professionally. Comparing this to a kid who simply put all of his GoPro clips straight off the camera onto Youtube with a terrible song. Of course it makes it easy to spot which was made on a GoPro.
But when you give the camera to someone who knows what they are doing (In this case, the OP), then you can produce some extremely impressive results. Sure the camera will never replace the RED that he has, but it is something simple, easy to use, and inexpensive.
In the end, it's not the camera gear you use to get the video, it's the person who uses the gear that determines the quality of the video.
