I've been following the threads here on POTN regarding the 7DII. Big Country, especially has had some real issues regarding his. I ran a 1DIIn for a LONG time, and about 2 weeks ago, got a 1DIV. I don't shoot birds, but I do shoot a LOT of grade and highschool indoor sports. I also shoot available light pics of my son. This camera is amazing. Indoor games shot at ISO 12800 are better than my 1DIIn's images at ISO3200. I seldom run shutter speeds lower than 1/1000 of a second, unless shooting pics of my son (who HATES to have his photo taken), but even when I put on my 50mm f/1.4, it runs like a Swiss watch. I think this camera is great for what I want to shoot, but I also don't shoot a lot of what others here do. I've used it in limited aspects of landscape photography, and in that role it with my 24-70 f/2.8 and it worked fine. I hope the issues with the 7DII work them selves out, and I cannot really understand why Canon stopped making this line; and NO, the 1Dx is not a camera I want, (not that I would be able to afford one anyways). I've always liked the 1.3 cropped sensor, but that may have been just me. In any event, I was able to find a great, albeit used, one on ebay for $1800 delivered to my door. Given that price point, AND from what I'd been reading about the 7DII, I chose the 1DIV, and haven't regretted my decision in the least. I still have my 1DIIn but am constantly being surprised by the 1DIV. Good luck in your decision. Happy Thanksgiving to all!
