And by 5D, I mean the original, Mark I. The release of the Canon 5D Mark II has put a ton of used 5D's out on the market, ready to be grabbed up by aspiring photographers. It is pretty incredible that a full-frame DSLR can be had for a little over $1100 (and dropping).
I bought my 5D new in the summer of 2006 just before my trip to Australia. It proved to be a truly excellent travel camera. There's just no way I could have covered so much ground in Sydney and the Blue Mountains lugging my huge 1D Mark II. It's just the right size for a small camera bag or backpack with a couple lenses (the 17-40/4 and 70-200/2.8 at the time). The charger and batteries weren't a burden either, which is a real consideration when traveling with a digital camera. Have you seen the charger for the 1D?
I was considering buying a 5D Mark II when it first came out, mainly for it's HD video feature and 14-bit color depth. Since then, I've started to lean more toward film as a real option for color depth and resolution, keeping the original 5D as my general camera. I'm also expecting the second generation of video-enabled DSLR's to bring some great improvements.
So before you blow your dough on a 5D Mark II, consider the original 5D as a real option; it still rocks. Instead, spend that money on some sweet glass that you can use for many (more) years to come.
