Lol of course it doesnt cost this. Ken Rockwell for instance has proven that great photography doesnt have to be expensive - see his review on a
$150 camera vs a $5000 camera.
The reason a lot of professionals go for these types of camera's is because they need a certain amount of flexibility and precision, and cheaper camera's obviously do have limitations, mainly to do with lenses they can support to be honest.
I have had some great shots (well I think so anyway) with my camera, yet its only a £200 - £280 bridge camera (dependent on where you buy), with a £30 set of 2400mAh batteries and 1 hour charger and a £40 2GB XD picture card and a £20 monopod, which I have to admit I never even use.
I doubt these real high end camera's would give much of an improvement in quality when considering the price difference. But at the end of the day, my camera is only entry level and doesnt have the flexibility of these. I can get addon lens extensions for it, and I am lucky in the fact the sensor and built on lens is extremely high quality and starts from 28mm to 300mm and has features like manual zoom and manual focus ring etc to keep it within "touching distance" of a low end DSLR.
I personally wouldnt pay anything more then a few hundred quid for a digital camera, I cant ever see me needing a full DSLR, but then I am not trained (yet) in using a camera professionally and dont particuarly like using the full manual mode on my Fuji to warrant the move over to a DSLR.
As long as it takes great shots, it doesnt matter on the cost, just because something costs more doesnt mean it will make you a better user.
For instance, I can get better shots out of my camera then I can out of a beast like Totopop is selling, merely because I wouldnt be able to control the camera and use its features well enough
You could probably DJ on an old set of belt driven decks better then I could on set of Technics 1210's - just because you have the experience and knowhow with decks and I have rarely used them in my lifetime, preferring CD's and MP3's.
So you see, a lot of it down the photographer rather then the camera, so dont be put off by the stupid pricing of these high end beasts, because in all likelyhood, you will take better shots on a lower end camera and be more comfortable using it then one of these hehe.
