It has 11 AF points and 9 of them are cross type points. Nothing can be worse than 6D's AF nowdays.I metioned the 6D may have the similar AF module as the new pentax k-5 II in another thread when digicame-info suggested the rumored 6D may have strong low light detection module.I'm really wondering how a native ISO of 25600 is not modern sensor tech. The D600 is all of 6400. Of course, its only hype, so we need to see the real tests, but, as long as we are comparing on paper, the sensor sounds pretty good. The AF is still a unknown, if the 11 points work, then thats fine for the intended users.
Another gem is the ability to autofocus at -3 EV. That is better than any Canon DSLR to date. Its literally focusing in the dark, and just whats needed when you are using that ISO 25600.
The only way Canon could achieve ISO 25600 was by weakening their color filter array. Red and Blue pixels are much more sensitive to green light than they used to be. Canon didn't innovate anything new there, for the 1D X, 5D III, or 6D. They cheated. I don't really call that modern, I call it cheap.
As for -3 EV, I think I mentioned that was a gem in my post above. Its certainly unheard of in any DSLR to date as fa as I know...previously the lowest light sensitivity was EV -2 (at least as far as I know). And it would be focusing in full-moon moonlight, not really the dark. When we can AF at EF -6, which would be starlight, then I'll be thoroughly impressed.
The Pentax K-5 II was announced 8 days ago claimed:
"The 16MP Pentax K-5 II DSLR is the company's 2012 flagship camera. It is built around a weather-sealed magnesium alloy and is bundled with the SAFOX X, autofocus sensor. This is designed to work in lower light than any of its rivals (down to -3EV) it will also provide greater accuracy when working with F2.8 and fast lenses. The SAFOX X also features more sophisticated focus tracking, to keep focus when the subject moves off the original focus point."
Ah, so -3 EV isn't unheard of, its just really rare and relatively new. Out of curiosity, how many cross-type points does the K5 II have? None? One? Many?
Frankly, I don't think a -3EV AF can work without an Autofocus assist lamp, let's wait and see.
