Another What dSLR should I buy?

[rolledmymazda]

1st, Hi all, new to the forum but I have tried to read most of the more recent posts on "what SLR should I buy".


I am coming from a Sony Cyber-shot DSC-V3


Most of the pictures are "sport" pictures, specifically MMA and Boxing.

- Ringside shooting, so NO FLASH! "low light"
- Mostly website pictures (but large size prints would be a bonus, poster size)
- Again ringside, so distance would be 1-24ft
- I work for the Local Combative Sport Commission, so MMA and Boxing seminars, with the "group shot" at the end.

Less important shoots.
Some car shots as I'm in a couple car clubs (Drive a 89 Nissan Skyline GTR w/6 speed Getrag swap)
- car club guys like their night shots ;)
- a few friends race local GT series, so some races/lap days, drifting and the odd drag race.

Price range
- $1300ish for just the camera

I am looking at the Canon EOS 40D

from what I have read ISO 3200 is good for low light?
1/8000 shutter speed
and CMOS Sensor again for low light?
- Compared to the Nikon D200?

also, the $1300 price range is a personal limit not a financial one, so I'd be willing to go to $2000 for just the camera, like the Canon EOS 5D, Olympus E-3 or Nikon D300. if it would help with my sport type of shot.
- EOS 5D 3 fps? this is a bad thing for sport shots right?
- Sony 700? at $1400 with close to same specs as D300? (one thing Sony does well is market their stuff, all the fancy words and technical jargon on their 700 page sure makes it look good, too bad I don't understand any of it lol)

And any lens info would also help, again mostly for low light, NO FLASH, sport shots.
Not sure of price range as I have never bought a lens, so $500-1000?


Haven't used any Editing Software before, but I'm a quick learner so that's not a issue.
