Considering Canon crippled the 6D to only 11 AF points with only 1 Xtype point
I just would like to point out that like the 5d2, the 6d has *no* real cross af point at all @f2.8, but if the horizontal-only f2.8 line cannot lock falls back to the less precise f5.6 overlay x-point. Thanks, Canon.
Sorry to go off-topic, but to speak to the prospects of the 7D2's AF system, consider from the FF world:
1DX: State of the art 61/41 AF system, state of the art metering with dedicated processor, fastest burst
5D3: State of the art 61/41 AF system*, but something like the current 7D's metering**, good burst
6D: Nerfed AF system (limited options), but something like the current 7D's metering**, slowest burst
* Yes, I realize that this royally p----- off 1D users accustomed to exclusive tech. As a 5D3 owner, I absolutely love this call.
** I don't study metering as often, but the specs seemed numerically similar if not identical from what I've (admittedly briefly) read.
So wouldn't it be logical for the following arrangement?
7D2: State of the art 61/41 AF system, but something like the current 7D's metering, fastest burst
70D: Ok AF system (decent but not 1DX/5D3), but something like the current 7D's metering, good burst
700D: Nerfed AF system (limited options),
for metering and slowest burst
XXXXD: Worst of everything, might spontaneously explode from users having even modest burst rate hopes
I fully understand why the 6D was nerfed. Great AF takes hardware (and therefore cost) to pull off, and they wanted (a) to get the 6D cost down and (b) protect the 5D3 as the all-around popular/mainstream FF choice. Mission accomplished on both fronts, but the D600 has far more AF points (albeit all within a hair of center) to sell against the 6D as a result.
But the 7D2 (a) will not be cheap (see my post on Page 5) and (b) is not in any way competing with the 5D3 unless you are the most discriminating pixel peeper who doesn't mind teleconverters or madly expensive long glass.
So give the damn 7D2 the AF system it ought to have -- the best one!
