[sport photographers] .. please help me to pick my new camera !!

[no_1]

hello everyone ..

i'm in a very hard spot and i really need you advise ..

whiten a few days i'm gonna bay my first SLR camera .. and i wanna spend my precious money carefully

so .. i'm gonna give you some pointers and wait for you recommendations :-

1- i'm gonna use it for sport photography ( soccer ) .. and it's gonna be most used in Stadiums at night time :cryin:
2- it should cost me no more than ( 800 - 850 $ ) .. :mad2:
3- i'm gonna use it mostly with the sigma version of [ 70 - 200 / 2.8 ] lens ..

::

by the way .. my first choice was nikon d300 or d700 .. but unfortunately it's to expansive for me ..!

now i'm thinking about the nikon d5000 which i heard is bad in focusing or something like that i'm not really sure !!

or the nikon d90 which i thinks is great but gonna make me miss the monitor of the d5000 !!

or finally the canon EOS Rebel XS .. which i have no info about .. but some people recommended it for me !

::

so .. the bottom line is i need a fast camera with a high ISO capability which i can use as a beginner in sport photography ..

::

i'm so sorry guys about my poor ENGLISH .. i did my best .. and i hope you understand what i'm saying ..

waiting for you replies ..

::

best regards
ADNAN

Question,

Is the Sigma already yours and what mount is it? If you went to Canon from Nikon, can you change the mount?
