Chiming in on the camera talk.
To be fair on the video the photographer specifically says the 50mm is a target for people looking to upgrade from the kit lens. For people who thought the camera/kit lens was an investment an additional $100+ on another lens is going to sting. I thought that he compared both Nikon 70-200 zooms but I could be mistaken. I see why he harps on it so much since 1/3 of his shots are where the Nikon fails.
As an anecdote. A guy I work with probably has $4K or so in camera gear over the past few years and he says that if he was starting again, he would probably go Canon. He likes shooting wildlife and family. A lot of the strictly camera talk that's been discussed here he has echoed unprompted. it's always nice to hear it in 2 places.
After seeing the videos it made me go check out the Nikon product line to get an idea. For just a 50mm prime and body I could get way more features and better photo quality for the money with Nikon. Though after that, I'm not sure where I would be going in lenses, and I'm sure that will weigh the scales heavily.
