Pentax should put the Sony 12mp full frame A7s sensor in a 4K K-1 camera for video and low light to use with legacy K mount lenses that are not sharp enough for 36mp.

Panasonic AG-DVX200 4K Handheld Camcorder with Four Thirds Sensor and Integrated Zoom Lens shoots 4K UHD at 60fps and has two SDXC U3 slots .

Sony and Panasonic will have 8K consumer cameras by 2020.

2TB SDXC and 2TB microSDXC cards will be coming for 8K video .

I would not want a 1TB card that is only rated UHS-1 since it would take forever to upload that amount of data. The UHS-II SDXC cards are 3x faster like the 2000x Lexar UHS-II SDXC cards. The new video speed class SDXC cards for up to 8K video should be out soon.

Pretec 12 GB CF - just $14,900 in 2004 !

You could buy two 512GB SDXC cards today but you can't buy a 1TB SDXC card today.

512GB SDXC cards have been out for some time so 1TB is not that big a deal. The new V90 SDXC cards coming are rated for 8K video so 1TB will be used for that high amount of data.

SSDs should last longer than HDDs. All of the drives I have purchased in the last four years were SSDs and all of my Macs , PCs etc have SSDs. Data centers are switching to SSDs.

Same here.

The new Sony Action Cam FDR-X3000 with Balanced Optical SteadyShot in 4K looks better that the Hero 5 with only electronic IS.

If the GH5 has no IBIS I might get this for 4K video instead for use with my non IS lenses like the 25mm F0.95 Nokton and 75mm F1.8 Olympus.

This was a smart move by Sony since there is millions of A mount lenses out there and some prefer a larger DSLR style body than the A7r II.

Looks like this will make A mount users happy !

I agree, the NX1 was ahead of it's time with both DCI 4K (4096x2160 ) and 4K UHD along with fast 15fps stills. It works great with my Pentax and Nikon mount lenses using low cost adapters. I also like that it has support for UHS-II SDXC cards and h.265 that takes up half the storage space of h.264 and a small fraction compared to motion JPEG that Canon is using on their latest cameras. I will keep my NX1 along with my Sony a6300, A7r , RX10 III and Panasonic GH4.

It's funny how Canon fanboys say 1080p is the standard not 4K. Right, 2mp is so much better than 8mp. Every major smartphone shoots 4K UHD along with a myriad of Sony and Panasonic cameras shoot 4K.

Poor Canon, they are still stuck in the 1080p world . Pay $2K for the XC10 point & shoot without EVF if you want 4K UHD. The XC10 won worst video camera of 2015, worst still camera of 2015 and #3 worst lens of 2015 at Camera Store TV.

I prefer 4K extreme low light night videos like this:
