I have a 7D, 1d3, 1d4& 5d3.... IMHO, the 7d does isn't in the same league as a 1d3 much less a 1d4... Drink the 1D koolaid, you'll see.... Files are nicer to work with, snappier feel, better build quality... I could go on... Between a 5d3 & a 1d4, closer call.... High ISO, 5d3, for me 1d4 gets the call most of the time for my sports stuff over the 5d3(which I like alot).
Not to stray, 1d4 is better than a 1d3... but twice as good? Hmmm tough call.
