Hi, I've done a search on this topic and can see that non-canon crop lenses (that don't protrude into the camera body) work on the 5D IV with its crop factor of ~1.7x, but I'm wondering if this will work on a 1DX Mark II also. Please tell me if my working is wrong, and your thoughts
Okay, so what I'm after is to be able to capture Image Stabilized shots with an Ultra-Wide lens. The perfect lens would be a 16-35mm F2.8L IS, but according to my other thread, that is unlikely to happen:

The full frame resolution on the 1DX Mark II is 5472x3648. Using Pythagoras the diagonal for the full frame is 6576 pixels. If I crop my 4K DCI video footage to UHD, I'm using the centre 3840x2160 pixels of the frame: 4401 pixels diagonally (well the hypotenuse). This is a 1.49x crop.
Canon EF-S crop factor = 1.6
Nikon FX crop factor = 1.5
Thus if I use a Sigma / Tokina lens designed for crop cameras I can get an EF mount lens with a 1.5x crop factor which would work well with a cropped UHD output from my 1DX Mark II, yeah?
1.49x is close enough to 1.5x ?
So I could capture the equivalent of 15-36mm footage in 4k UHD with IS with a Tamrom 10-24mm F/3.5-4.5 Di II VC HLD. This lens also takes filters.
Is that mathematically correct? Thoughts?
