FroKnowsPhoto has posted a video asking with Canon full frame camera is for you (plus the EOS 7D Mark II). Jared talks about the EOS 6D, 5D Mark III, EOS-1D X and the APS-C EOS 7D Mark II.
I agree with most of what Jared says, outside of the EOS 6D. I think for $1499 after rebates, it’s still a buy now camera. A replacement is going to cost closer to $2000 than the current $1500 pricetag.
