Hi, this is my firs post in the forum and I'm also about to make the jump to my first dSLR. BTW Gordon, I love your video reviews, it's nice to see the equipment one is planning to buy handled and explained by a pro, it gives you a very clear idea of what to expect (and what not) from the product one is considering.
Yves, I don't want to put you back into struggle just when it seems you've made you decision, but are you sure the D40x is the best choice for sport shooting? I mean amateur sport shooting of course, it's plain that pros out there use equipment (both the bodies and the lenses) far superior and well beyond the budget of almost everybody.
Perhaps Gordon or any other more experienced person will correct me, but it seems to me that one of the weaker points of the D40/D40x is that they only come with 3 AF areas (while the incredible D80 has 11 and the EOS 400D has 9 directly inherited from it's upperend sister the EOS 30D). I think you could find yourself loosing a few shots in Nurgburgring with the D40x that you wouldn't with the EOS 400D or better still the D80.
Note that I'm trying to show you the posible advantages of going for another model while I'm almost decided to buy myself a D40 (I'm not using my camera for printing life size posters at present
so I'll spend the money of those extra 4 MPs of the D40x on another lens or perhaps a flash). The difference is that I'm not planning to shoot sports regularly (though perhaps on ocasion) so the 3 point AF is not such a big issue for me, nor having to navigate a little more through the menus to adjust ISO or WB, I'm a newbie and as such I just have to love the in-camera help system of the D40/D40x. As for the EOS 400D, I love it, specially it's auto cleaning device, but it's a bit more expensive than the D40 and the kit lens is far worse that the Nikon's, so I think the D40 will be the starting point for me, in a couple of years perhaps I'll upgrade the body to the descendant of the D80.
To make my point with just one phrase: I'm pretty sure the D40/D40x is capable of making stunning fast action pictures, but I also think that you would fare better with a few more AF points (specially the D80, which BTW comes with the incredible 18-70mm kit lens, far superior to the 18-55mm of the D40 and a world away from those of the 400D).
Cheers from Spain.
