Not sure if this should go in the Motorsports forum since its mostly about sharing pictures.
I've been asked to do some official photography for the Targa Newfoundland rally next month. Its a 6 day, 2200km tarmac rally covering rural and urban roads all over the island of Newfoundland on the East Coast of Canada.
I was still new to SLRs last year and my pictures represented this but I was also shooting for myself so it wasn't that big a deal. I've done a lot of motorsports photography since then but I'm still rather anxious. I've done my best to make sure the organizers expectations are on par with my abilities at this point but you know how it goes. They're looking for pictures for their website, for various advertisements and magazine articles.
Anyway the advice I'm looking for is about some shooting techniques, sunny bright days are easy but the weather for this event often doesn't cooperate. Rain, fog and twilight stages are common. Should I be using my 430EX for these days? I've never used it for motorsports before so I don't know if it will 'harshen' the pictures.
Unfortunately my only long lens is my 70-210 f4 which is just marginal at best and very slow at focusing. My 28-135 produces sharper more reliable images but sacrifices the reach. That may or may not be an issue depending on where I can be relative to the cars of course. I'm trying to rent a friends 70-200 f4L but I don't think he's going to go for it. (And I really can't blame him there)
You can see my pictures from last year here and see where I'm coming from about the conditions:

We won't even get into the fact that I've been asked to take pictures at the Black Tie gala at the end of the week. Thats a whole other pucker factor.
