This post has really got my attention... thanks CR. I'm quite impressed at the 70D specs listed. They are not 'unreasonable' - as in, re-using the already very good 7D's AF, and some other improvements (eg LiveView AF, articulating screen, WiFi, etc). The new '5 times quicker' contrast detect AF sounds particularly useful in some applications (I wonder if that only applies to STM, and how much other lenses, eg USM - also benefit?)
As I have a 7D - and love that camera - it does give me hope that a very good improvement is around the corner for the 7DmkII.... as that will probably be my next camera. Because I use the 7D for all my photography needs - from landscape to macro to wildlife to events to casual sports and portrait - an improvement in the sensor (namely lower noise and better DR) will be come.
I have taken so many great photos - even landscapes and portraits - don't let someone tell you an APS-C can't produce stunning photos in those genres, even though FF will naturally have an advantage there... the quality of the final result is more about lighting, composition and knowing how to use one's equipment - including great lenses.
I'm looking forward to seeing photos soon - that were produced by the 70D - ie Canon's exciting new 'camera-on-the-block'! Yay for technological improvements. Roll on 7DmkII.
a happy Paul
