Re: Here Are Some Claimed Specifications For One of the Prototype Canon Full Frame Mirrorless Camera
Perhaps not.
First of all, there's a question of selectable AF points. Even if you have millions of data points for creating focus with DPAF, the camera will only offer you so many to choose from.
Secondly, just because it's a mirrorless doesn't mean that it can't have PDAF. We could potentially be looking at a hybrid system, like Sony, where there is PDAF and DPAF operating simultaneously, as they do with PDAF and Contrast Detection.
Is DPAF superior to PDAF for autofocusing on every type of subject? I don't know this for a fact, because I really don't use DPAF enough on a DSLR, and I down own a Canon EVF camera. But even so, comparing an M5 to a 5D wouldn't be fair.
In the Sony world, the PDAF is used for fast autofocus; the CDAF is used or needed for a lot of the "advanced" features. It's one of the odd paradoxes of using an adapted lens through Metabones: you have your choice of using PDAF and getting usable autofocus minus all of the cool features ("Green" mode), or getting all of the cool features but having AF that's horrendously slow ("Advanced" mode).
ahsanford said:dhachey77 said:63 AF points! Is that a joke?
That's why I think this is off. Who says it has 'AF controls like a 61 point AF predecessor'?
It would say:
X# of AF points
Touchscreen AF pt selection like the 5D4
Also, it will have a s---ton more AF points than 61 because it's DPAF!
They may discrete-ize (discretize?) the points into something easy to select with a joystick, but there will be a ton of AF points. At B&H, the M5 and M6 didn't publish their AF pt numbers, but the mid-level crop M50 lists 143/99 depending on contrast vs. phase detect. Expect no less from a much pricier FF rig.
Again: not buying this rumor.
