I use Panasonic Bridge Cameras. The DMC-FZ300 has this incredible zoom lens of 25-600mm and F2.8 over the entire range. I must admit though that using it beyond 400mm it gets tough to get a steady hand held shot, but it works great for Tractor Pulls and Drag racing. I usually travel by Motorcycle or Moped, so carrying all that extra glass isn't really practical, and at Motocross on a dry day there is too much dust to swap lenses anyway. I also have the DMC-FZ2000 and that is my main video Camera and I do the close ups with the FZ300 as it's low light capability is not suitable for wide angle shots. I bought these 2 Cameras for very specific reasons, but it's more important to get really familiar with the camera you have so you can react fast. Some folks focus on the equipment a lot, but the best Camera is the one you always have with you; it's the one that gets the shots :)
