So a ~2.5 effective FF crop with the asp-c sensor and the 1.6 crop?

The crop part wasn't unexpected but the lack of dpaf in 4k is quite the downside - this has been confirmed?
I wonder why 30 fps couldn't have been done either, seems a bit of an odd limitation

It is 2018. UHS ll was introduced back in 2011 and it is expected to be in a camera in 2018.

But if it's of zero benefit, and UHS II cards just cost more, who cares?

Wow, no DPAF in 4K. Never mind, no longer interested. Maybe next time, Canon.

Wow, is this true?

Yep

I really should not be surprised, but I am. Why would a company make a product great by pairing their most powerful feature- DPAF- with a new feature- 4K (okay, new to Canon cameras)- that so many people wanted. They ALMOST had my money.

Because that would make it much too attractive for people   ;D

 The crop was kinda expected (although I think it comes out to ~ 2.5 FF equiv which is fairly heavy) but the lack of dpaf means it doesn't really have any standout video feature as a canon camera.

For the further cropping in 4K video, does it mean that it will use a small part of the censor but focal length remains the same as APS-C?

The sensor's resolution is 6000x4000 (=24mp).  4k is 3840x2160.

1.6 crop factor, if you applied it proportionately to the sensor would give you 3750x2500, but of course, the aspect ratio is different.  So all 1.6 crop means is that Canon is taking the center 3840 pixels horizontally and the center 2160 pixels vertically when recording video.

The lens hasn't changed, so the focal length remains the same as APSC for the purposes of perspective.  But for field of view, because you're only getting the center 1.6 out of APSC, you'll need a wider angle lens to capture the same frame.

I suspect that this is because it will be a differentiator between their $740 camera, and their future $1000 camera.  After all, what other $740 camera has DPAF 4k video?

So much for getting the vloggers back.

Fair enough- let’s get that camera out, then. Time to turn out some good products instead of protecting future brackets of ones that don’t exist yet.

But if it's of zero benefit, and UHS II cards just cost more, who cares?

Yep it is definitely of no use for you  ;)

Crop factory and no dpaf in 4k is disappointing. Let us see if at least matches with M5 with rest of the stuff except those missing physical buttons. Don't know why did they release this. Instead, they should just reduce price of M5.

no real use to anyone unless there's the communication lanes available to run it at a higher bus speed, outside of looking like the ultimate spec sheet warrior.

why would it have to match the M5 - it's really sitting above the M100.  not around the M6/M5 level of cameras.

UHS II cards are a way more expensive, so what's the point, unless the camera does something that takes advantage of the faster card?

I'm not saying that UHS II cards serve no purpose; just that they serve no purpose in this camera because of limitations either in other subsystems or artificially imposed to fit a $740 price point.

Right -- it should have specs between the M100 and M5/6, but (as with most Canon consumer body releases) because it's newer, it will get some nice features that will make it into the next M5/6's.

In practice, it looks like the 15-45mm kit lens on this would have a ~38 - 112mm effective focal length when using the 4k video mode, which is pretty similar to the ~40 - 120mmangle you get on the 5dmk4 with a 24-70mm lens in that camera's 4k mode.

performance tweaks I'm sure need to be done.  they have to sample 8 million AF points in between frames for DPAF. contrast is taken as part of the frame capture.
