Nicholas, is that a compact camera or a SLR? Only SLR's produce suitable results for aviation photography, and I struggle with my SLR... But it sounds like you've a compact camera, that just won't work here. L-188, look for used equipment!! I know a proffessional photographer who says that you can get REALLY long used lenses for REALLY cheap. He mentioned a pricerange of about $150-250. He's got several cameras(FastGlass guess what, it's someone partial to Nikons!!), one is an N90s and the rest i dont know... Crud why am i not asking him for tips?!
