canon 1d mk 4 settings for roller derby indoor

<p>I have a job covering roller derby indoor and would like opinions on autofocus settings from any users with a 1d mk4 as this is what i will be using.<br>

The skaters will be mooving fast at times and some erratic pushing and jumping shots.<br>

All this will be indoors not the best lighting in the world.<br>

lenses at my disposal= 70-200 is mkii 135mm f2 24-70f2.8 50mm f1.4 <br>

I have been using a mkiii for sports so the mk4 is new to me so is this sport.</p>

<p>How close can you get, and are you allowed use flash?</p>

<p>Are you shooting banked track or flat track? It makes a big difference in speed. I shoot banked track, it's a lot more exciting. You do have to watch out if you are shooting up close (which gets the rails out of the photo), skaters can come over the rails far faster than you expect.</p>

<p>I have never had problems shooting roller derby with flash. Nobody ever complains about it, and I've asked. I use a Mk3 and set up the AF with what are probably considered "standard sports" settings.</p>

<p>Typical shot.</p>

<p>Flat track and i will be able to use flash should be able to get close.</p>

<p>With flat track you can't get as close usually, the problem is that they can easily skate off the track without the barrier to slow them down. On the other hand, flat track speeds don't come close to banked track speeds, so you can't get hit that hard. Sometimes there is a pit for the players at flat track and you can shoot from there. You need to look into the setup if you can, maybe there are photos of the track on the web.</p>
