30D. no need to think about it. surpasses the 400D in terms of usability when it comes to build, frame rate and higher iso control. not to mention faster shutter lag and faster mirror blackout relative to the 400D.
Definitely the 30D wins in terms of features. But I find myself asking whether the TS needs the features.
No,pro as in the function.ie the ISo,shutter,FF and so on which i read from dpreview.
I have a drycabi already.The F1 im thinking of probly using the Sigma 70-300mm which cost only $120 second hand here
FYI, pros/enthusiasts who shoot F1 from the stands usually use lenses 300mm or longer, which are usually fast (f/2.8 or f/4). Use the 70-300 and I'd rather you sit in the stands and enjoy the race. The AF speed will make you cry.
sorry i referred FF as burst frame.
Sorry to be harsh but I don't see how FF can possibly relate to frame rate.
All in all, I'd think the money would be wiser spent when you learn more about photography. Buying a DSLR to shoot in P or Auto is not wrong, but it's not wise usage of money, and not wise usage of the equipment placed in your hands.
Of course, it's your money and you can spend it however you wish, but I think that learning more about photography first should precede plonking so much cash down on something which you will use 30% of the features of.
Frankly I don't see why you need the extra one stop of ISO (both 400D and 30D shoot as high as ISO 1600, but 30D has the option to shoot at ISO3200, but I've never used it; it's just too grainy to process out), the extra FPS (most enthusiasts survive on 3 fps. I seldom shoot continuous to begin with) and the better build (you're not a pro who throws your equipment around. I hope you don't even throw your equipment around to begin with).
