Let me compare the 70D to the A6000.
I know I specifically mentioned the A5100 when talking about the sensor, but I was speaking generally of Sony's crop cameras compared to Canon's in terms of overall camera capability so I'll use the a6000 as my example.
The a6000 is much cheaper at $800 (actually $648 now on Amazon).
Ok, that's true.
The a6000 is full metal compared to 70D being plastic.
I haven't seen any information on the internals so have no idea on whether or not this is true.
The a6000 shoots up to 11fps compared to the 7fps on the 70D
Good luck actually tracking anything that's not moving in an easily predictable way.
The a6000 has a 179 focus points compared to 19 on the 70D
And exactly zero of those are cross-type whereas the 70D has 19 cross-type points through the VF and ~20 million line-type on the sensor.
The a6000 shoots 60p video at full hd (note: also with better quality)
This is true.
The a6000 has 100% viewfinder coverage compared to 98% on the 70D
The A6000 viewfinder has better coverage but it's tiny as hell and overall pretty awful.
On top of that, it has a superior sensor with more dynamic range, color sensitivity, and tonal range.
These are also true.
Another thing you can't overlook is that the A6000 has the typical godawful ergonomics and controls that all Sony mirrorless bodies share.
