5D IV-Zoom and crop factor

[Cunha]

Hello,

correct me if I´m wrong; please.

Using the 5DIV in 4K video mode, the crop factor is exactly x1,7. Or less (rumors?)?

Using these Canon zooms in 4K what will I get?

24-70mm wil be 40-120mm?

16-35mm will be 27x60?

Less wide than the lens native focal lenght in a Full Frame.

This means I must put myself a bit far way from my subject to compensate.

Thank you for your help.

Hello Cunha, 

There are no official specifications that mention a 1.7x crop factor when shooting 4K with the EOS 5D Mark IV.  I see where some web sites mentioned that but nothing from Canon which means I cannot substantiate whats on a third party site.

Thank you Tim.

But there is indeed a crop factor .-) when shooting 4K.
