FOV guide for Scarlet

The questions are floating everywhere. Can someone in position please clearify things?

How is crop-factor when shooting in 4k? (a lot of people do think in terms of crop factor)

How are lens options on each of the mounts? Links would be very useful

crop factor is around 1.5 or 1.6 the same as aps-c

More like 1.4 for full frame 35mm "L" lenses and 1.1 for 7D "S" lenses . . . at full rez. Much less as you rez down in camera ie: 5K to 4K

well most people will be shooting 4k not 5k which is only for stills in scarlet so for 4k the crop factor will be 1.6 if I'm not mistaken

There's no vignetting on Scarlet using EF-S @ 4K? APS-C is smaller than S35, so I'm just wondering. I'm sure 2k is fine for EF-S. I dont actually own any EF-S lenses at all, but it would be good to know when I need to rent lenses in the future (the 17-55 f/2.8 is nice).

OK, let's look at this relative to a 24mm x 36mm "full frame" image.

The Epic sensor they're using is a 30mm x 15mm sensor, so it starts off with a 1.2x crop in terms of width and a 1.6x crop in terms of height.

So when you shoot at 4K that's a 1.25 crop multiplied by a 1.2 crop for width, so that's a 1.5x crop for width. For height it's 1.25 multiplied by 1.6, so the crop factor in terms of frame height is actually 2x.

So 18mm RPP on Scarlet4K will correspond to a 28mm in FF.
The big question then is, what is a good solution to cover the 18mm FF area?

With canon mount, the market is massive, but how do we know which lenses can cover the sensor in 4K and if they will be "sharp/good enough"?
