Hi guys
I am currently looking for a new lens as recently been appointed "official photogrpaher' for the local rugby team. I am looking to buy a lens to suit. My budget is not that high as i am only volunteering for my mate. Max spend is around $1000 Aus. I am fairly close to the sideline running up and down with the newspaper guys with their L lens.

Massive lens envy!!
I am currently using a 75-300mm non IS and Non USM ($200) lens and the results are not that great. I was almost going to buy the Canon F4 70-200 USM (non IS) but concerned that i need more zoom. I noticed the Sigma 120-400mm at the local cam shop and the price wise is great. But wondering how it performs for action sports.
HSM compared to USM?
So my question is from the list below what would be the best lens for contact sport? I am close and on the side line, I will be buying a monopod shortly to assist so IS need not be an issue.
- Canon 70-200mm F4 ($800ish)
- Sigma 50-500mm (seen in local shop on special for $1200)
- If i consider the $1200 on the sigma its not that much more for the Canon 70-200mm f2.8 non IS.
- Sigma 120-400mm DG OS HSM ($850)
- Sigma 150-500mm DG OS HSM ($950)
I have 2 small boys soon to start sport so the lens will get plenty of use.
Any advice would be most welcome
Thanks
