So I find I like taking pictures while outdoors hiking, it likes to rain a lot. I take my XSi out in my backpack, I haven't had any issues with a light misting, and frankly, if it ever breaks from a light misting then so be it. But a lot times I don't take pictures because it is actually raining. Is the Nikon D300s really weather sealed? Same as a professional Nikon? I see on the website it says dust and moisture resistant or something of that nature. Obviously it won't take a dunk without having...issues....but what is the extent? The D700 looks like it is a FF sensor? That is a lot more expensive, and I am happy with my 1.6x crop and am happy with 12mp. But is the D700 better weather proof? I am not interested too much in switching, as I like the function and layout of my XSi, but I would like to move to something more weather proof, and when it comes to spending $1500 (at least) for new body (and even more for a Canon as far as I can tell), I am not vested enough yet to avoid the switch. I just have one lens so far, remote, batteries, and memory cards. ..and the D300 seems to offer a professional AF. I guess what I am asking, which Canon/Nikon models are suitable for outdoors? Are weatherproof Nikon lenses comparable in price to Canon? I need to figure out where I am going before I start putting money into glass.
