It's aimed towards hard-core professionals who have studios and stuff. It's an investment that should make money. it's not for your average deviantart casual/amateur photographer
Nail hit firmly on the head.
Back when I was younger and heavily into photography I used to own and use a pair of Canon F-1n's and a pair of Canon T-90's.
These were the 35mm film versions of the above at the time (I'm talking £1k a body for the F-1n and £650 a body for the T-90 in the early '90s).
The pictures they took were arguably no different that with any other Cannon body, but thet did offer features that no other camera in teh range did. The T-90 had a inbuilt 5fps drive and 1/8000 top shutter speed, making it a significant choice for sports photographers of the day. The F-1n was an amazing tool, so well built it could stand almost anything, one of my bodies had a pint of beer spilt over it when I taking shots for a friends band. wiped it off and it never missed a beat. I swear you could you that damn thing as a hammer.
Thats what yo pay for here, the difference in built quality from amatuer to pro kit is huge.
Anyway camera bodies have always been the cheap bit, now lenses that when things get silly.
EF 400mm f/2.8L IS USM $10,833
EF 500mm f/4L IS USM $9,055
Any sports photographer is almost certainly going to want both of those, and all that before we start to look at larger format stuff.
Just take a look at the Phase One stuff (and remember thats just for the camera back - the body and lenses woul dbe on top of that), starts at around £11,000 and rises quickly.
