Hockey tournement Batam B

[pjibe]

Here is a few pictures I took last week in a Hockey Bantam B tournament
where my son was playing. I took these pictures with a Sigma lens 70-200mm
f/2.8 that I rent with my Canon Rebel XTI. I'm in a process to decide wich
telephoto zoom I will buy.

It's my first experience in this area and so far happy with the results
knowing that I need more experience. I was wondering if we can expect even
more picture quality with more experience. Do you have tips to give in order
for me to have better results.

Even with a f/2.8, I was working between ISO 800 and 1600 to have a shutter
speed of at least 1/250 at 2.8. I found these type of ISO very noisy and
I found desapointing the contrast between the ice an the player. The players
were looking dark.

thanks
