the 70d is the best aps-c camera so far. i have owned or tried them all, the iq is the same as the 6d up til iso 3200
In fact, I believe the 70D is in fact the 7DMkII
because Canon consolidated its lineup mostly by stepping down the specs of the 'old' product as follows (I've posted this earlier, elsewhere on the forum):
The 5DMkII was combined with the 60D and has become the 6D (For enthusiast stills/MF shooters
).The 7D was combined with the 60D and has become the 70D (For enthusiast aps-c sports and wildlife shooters with AF lenses).
The 1DsMkIII was combined with the 5DMkII and has become the 5DMkIII. (For studio and professional use but with AF lenses).
The 1DMkIV was combined with the 1DsMkIII and has become the 1DX. (For professional use in all conditions but with AF lenses) This is a step up of course but the ability to play well with MF lenses was lost.
Note that this is in line with the way the Canon Europe site has listed the XXX(X)D and M camera's 'for beginners', the 60D,70D,7D,6D 'for enthusiasts', and the 5DMkIII, 1DX and 1Dc 'for professionals'
So from this we can conclude that we already have the 7DMkII (it is the 70D),
and the 1DsMkIV is here as well, it is the 5DMkIII.
