Struan, that third one is a screamer, that is the first racing picture where I have seen pits. Although I assume they weren't meant for the cars in this instance.

Nathan, there are many of these events in this country but they do require some good planning and you may end up travelling near and far.

We recently had a good historic event at Philip Island the week before the Grand Prix.

This is lifted from the Age:-
And, in contrast to this weekend's formula one circus, it's quite probable you will bump into famous drivers, such as Vern Schuppan - former grand prix and Le Mans ace - milling around the pits or strolling through the crowd. Yes, you can shake hands, say hello and chat.

The intimacy of the event is rare in this age of no-go zones and automaton security guards. This is a relaxed and friendly meeting, despite a collective field of glossy machinery estimated by organisers to be worth more than $40 million.

There are cars as diverse as ancient Bugatti racers to the world's most powerful race car of its day, the Porsche 917/30, which was so successful at the time that officials changed the rules.

In motor sport, the chance to witness an object of absolute domination doesn't come around very often.

The Porsche 917/30 is such a car; an awesome, intimidating behemoth that didn't merely beat its opposition, it smashed it with clinical ruthlessness on the way to victory in the 1973 Canadian-American Racing Series and is cited as the car that killed Can-Am racing.

An evolution of the 1970 and 1971 Le Mans-winning 917/10 cars, its 5.4-litre, turbocharged V12 engine could make up to a staggering 1178 kW in qualifying trim and was capable of speeds up to 355 km/h.

Although not employing the "ground effects" aerodynamics of formula one racers, Porsche Museum director Klaus Bischoff says the 917/30 gets significant aerodynamic advantage from its low, improbably wide stance and a massive rear wing.

These days the 917/30 is occasionally used as a guest pace car. "I don't know why they ask us to be a pace car, because usually no one is able to keep up," says Mr Bischoff.

End of the Age stuff.

As for another lens, what about a mirror lens. I have a Sigma 600 f8 mirror lens and it is perfect for getting closeups of cars/bikes on a track. The downside is the speed, but with 400 ASA film and Australian sun you will be shooting at 1/250.

It almost hand holdable, but I find a monopod is brilliant for this type of set-up.

I picked mine up about 15 years ago for $180.00, recently there was one that sold in the photo trader for $150.00.

There were also a bevy of 300 f5.6 mirror lenses about 15 years ago, not sure what brand they were but someone here may know. For tight tracks that would be better.
