I have to say, this camera is constantly convincing me that it has everything i need - fast accurate and sufficient AF system for tracking, great IQ/ISO performance (with 1.6 crop factor), liveview dual AF focusing, which is very useful, only my 24-70L is very poor regarding sharpness performance on 70D.
I have to admit I was close to sell my 70D, because my 5dmkII suddenly died and i was 99% ready to buy 5dmkIII.. instead i kept my 70D and bought 5Dc - best decision i could make
5Dc is working with 24-70L no issues at all, all pictures are sharp as should be, weird thing is, while i had to use MFA on my 70D, my 5dc is focusing right out of the box, i saved over 2000$ on camera. Don´t know why, but i really like pictures from 5Dc more than from 5DmkII.
I also tried 7D mk II, but couldn´t justify the price, for me, it´s absolute overkill - 70D IMHO works great even without those fancy additional AF points, but i like f/8 AF and improved weather sealing though.
