Hi everyone, Another big step for me. I stepped in to the DSLR world last year with a used/secondhand EOD 40D with the kit lens EF-S 17-85 IS USM and I have to say that I'm loving each moment I'm out with my camera shooting anything and everything that interests me.Since then I've purchased an EF 70-200 L f/4 USM and the EF 50mm f/1.4 USM and Ive taken some pretty good photographs with these lenses. My wife and I was on holiday over the summer and there was a guy with a EOS 5D Mark I with a 24-105 L IS USM that got friendly and was kind enough to hand his camera over and have a play around with it. I really felt a difference with the 5D compared to my 40D (I'm not underestimating my 40D in anyway, I love it) and I felt the need for a Full-Frame Body. I've been surfing around for quite sometime looking for good condition secondhand full frame bodies...and I think if I wait patiently a little bit longer I would get a better deal with all the new models like the 5D Mark III and EOS 6D out soon. I'm no where near any of the above mentioned....but I've look at a 5D Mark I 12.8mp and a 1D Mark II 8.2. Both the same price and seems to be in good condition. I know that I would be stupid to be looking for an excellent condition body when it comes to these two models I would really appreciate if you could give your opinion on these two camera models and which one should benefit me on the long (phew) run? Maybe someday I would get a 5D Mark III or a 1DX....but by that time they would be called different names Thank you in advance and have a great week.
