Bizzare? You're living a very sheltered life, son. Looks like a Mamiya press camera - probably a 23 - to me. Very nice cameras with excellent glass (as is always the case with Mamiya). I think that's what it is because of the squared off top and the left hand grip for the camera. Probably the normal 90 - 100 range lens from the look of it. Then again, that is a camera I desire so I may be reading more into the shot than is appropriate... <shrug>
I'd be more curious about what he saw that was that interesting to shoot because he's terribly concentrating on something... 😱 Though if nothing else, he should be cheered on as he's using a real camera that will only ever take film... 😎
