Hey guys, new to the forum. I'm leaving a Panasonic Lumix DMC-FZ20 behind in favor of a DSLR. I love to do aviation photography, and take pics of my car and all my buddies cars at the weekend get together and races at the track. I am really interested in the Sony A200 with the 18-55 and 70-300. The 70-300 would suffice for aviation stuff out at the airport where I need to stretch out and catch them from distance. I like the D40 too but its only 6 megapixel. I'd like a little more room to work with. The Canon's just don't fit my budget at the moment. I can't justify the cost of the D40X and two kit lens versus the A200 and two kit lens unless the 40X is going to really bring that much better of an image quality. Let me know what you guys think...you're the experts right?
