I went up to Laguna Seca raceway, last weekend, to try to improve my auto racing shots. Keep in mind that this track is a very hilly place to watch a race, especially, if you want to get up to the "CorkScrew" corner at the top of the course. I talked with a motorsports photographer, before I went, by e-mail, and decided that a three lens kit would be best. In my case it was like this: Nikon F4s Nikkor 80-200mm f4.5 AI Nikkor 300mm f4.5 AIS Nikkor 35mm AF f 2.0 I thought I tossed in a new purchased 50mm f1.8 AIS to test out, but I grabbed my 24mm f2.8 AIS by mistake. So, make it 4 lenses. I also carried my Slik tripod, in case I wanted some sharp, non panned shots. Add to this my waist bag, which is sort of large, and my day pack to carry water and change of shirts, if the weather changed from morning to mid day. I also brought along and experimental "step" to attach to the chain link to get me a bit higher, as some of the fencing is just above eye level for me. This was made from a piece of aluminum bench, cut to size with rope attached. None of it weighed that much, on it's own, but all together, it got to be rather HEAVY to carry around , up and down hills, at about 90 degree temps ! I just put it all on the scale and it totaled 25.31 pounds. As I type this, that doesn't seem that much, but each time I picked it all up and strapped it on, it felt heavier and heavier. If the shots I took of on coming cars, come out sharp, the almost 6 pound tripod stays home, next time. I may be in the market for a light, but sturdy monopod, if they don't. Perhaps just because you CAN carry it with you, doesn't mean you SHOULD bring it along. Just a bit of advice for those that may think of doing the same thing.
