A theoretical question (Page 2): Whatever Canon puts inside its cameras should stay inside its cameras unless you want to do something unusual.

A burning question.
If it has a new, denser sensor,
If it can capture 4k,
If it comes with a newer processor,
Will it necessitate the removal of the anti-aliasing screen for higher acuity when used in 4k?

Inquiring minds want to know.
(OK, maybe only I want to know).

If you want great 4K, get a Lumix GH5, GH5s, or G9. No AA screen to worry about.

MP wars are over. All sizes of sensor have valid uses. Find a camera with a reasonable blend of features that meet your needs and go make photos and videos!

Whilst I agree, and I do believe that Canon is catching up, Sony is huge, and makes many of the sensors for smartphones, as well as Nikon. It's going to be an interesting game. Canon could use Sony sensors if they wished to, and have acknowledged that, which would be trouble for Nikon. Perhaps Canon is being kind to Nikon.

Love whilst!!

As canon has produced the world's largest ultrahigh sensitivity CMOS Image Sensor I don't think they are lacking in capabilities as much as taking a more conservative approach. Canon has very deep pockets not fueled strictly by consumer camera sales and I would not write them out.

How about Phase One and many of the other Medium Format Sensors; I believe you're talking about just the 35mm-sized sensors, eh ? I believe that several of the MF sensors are well over 100MP. The best of the Canon sensors are less than 1/2 of that.....

I suppose my real question is:
Can 4k be achieved with the anti - aliasing screen doing its job.
I could care less about 4k.
I would just like to see the the screen gone.

4K will be fine with an AA filter. Maybe even better. Are you aware that camera's without an AA (also known as "low pass") filter are prone to issues with moiré? https://photographylife.com/what-is-moire

4K actually is a lot lower resolution than a current Canon 80D, 24MP, APS-C format camera (although that camera DOESN'T do 4K... it's max is HD).

According to Wikipedia: There are several different 4K resolutions in the fields of digital television and digital cinematography. In television and consumer media, 3840 × 2160 (4K UHD) is the dominant 4K standard. In the movie projection industry, 4096 × 2160 (DCI 4K) is the dominant 4K standard.

A 24MP DSLR sensor is 6000 x 4000 pixels.

Current Canon models that can do 4K include:

EOS M50 (mirrorless)... 24MP, 6000 x 4000, APS-C (max video resolution: 3840 x 2160p at 23.98 fps).
EOS 5D Mark IV (DSLR).... 30MP, 6720 x 4480, full frame (max video resolution: 4096 x 2160p at 23.98/24/29.97 fps).
EOS 1DX Mark II (DSLR).... 20MP, 5472 x 3648, full frame (max video resolution: 4096 x 2160p at 50/59.94 fps).

After recently introducing the M50, I'd be surprised if Canon didn't introduce a 4K-capable APS-C DSLR soon, like a "90D". However, it's hard to say when they'll get around to it. Or if it will even be the 80D-series models where they'll introduce 4K. It might instead be the more upscale 7D-series (the Mark II is 1.5 years older than 80D)... Or the lower spec 77D or other Rebel/xxxD-series models ( which tend to be updated more frequently).

Of course, there are also the Cinema EOS, if your pockets are deep and you get really serious about it...

C200... 4K, 4096 x 2160, up to 60 fps
C700... 4.5K, 4512 x 2376, 4.5K up to 100 fps, 4K up to 120 fps
C200 Mark II... 4K, 4096 x 2160, up to 30 fps.

I don't know if they use an AA filter or not. I know some of them have built in neutral density filters.

The 5DIV has a low pass filter and it shoots 4K.

No, he is talking about the Canon CMOS sensor that is 40 times the size of a 35mm sensor. It is a specialty use sensor.
