Soooo.....not to bring up an overdiscussed topic yet again, but I'd really like everyone's feedback / opinions on this decision. If one hopes to upgrade to a nicer full-frame sensor one day, is it worth getting the 5D original over the 7D simply so that the lenses we collect will be useful for the upgrade someday? Some facts: Portrait / low light / some landscape / scenery / architecture / general action (kids running around, not sports or true wildlife photography) is what's important to me I like shallow DOF in general, and have heard that full frame achieves this at smaller apertures than apc - should that be a factor? I'm not heavily invested in any lens type, and this is what really draws me to the original 5d - so i can easily upgrade someday to another FF. I really like that the 7D is newer and in general looks and feels like a modern camera with a ton of powerful features. The 5D is older, looks older, etc. - not sure if I'm being nitpicky on this front. The two main things that are "negatives" in my mind for the 7D are 1) not full frame and 2) boy do I wish it had dual SD slots like the nikon d7000 - but i just like the handling, image rendering / colors, and controls of the Canon way more, which is why i've eliminated the d7000 from my list after much debate. So from the memory card perspective - no difference between the 5D and the 7D. Thanks in advance for your feedback!
