I haven't figured out Samyang's naming convention yet but the lovely 8mm f/2.8 fisheye I have says UMC E (former for ultra multi coated) where I assumed "E" was indicating the same thing as on Sony lenses ("E" being used for Sony E-mount APSc lenses). Of course, until the launch of a7/7r, we didn't see FE designation.I searched to find out as well. It appears its for APSc as the release mentioned Fuji X, Smasung NX and emount so I am assuming APSc as Sony FF is FE lens.

Now I wonder if CS implies Crop Sensor and if that is the case, that would be Samyang's choice to differentiate between FF and any lens that is not FF.
Sigma uses DG for FF, DC for APSc and introduced DN for mirrorless (not differentiating various formats within, so far).
Tamron has used Di for FF, Di II for APSc and Di III for mirrorless bodies.
On E-mount, Sony is using FE for FF and E fir APSc
On A-mount, there is no designation for FF (being aouny which was all FF until digital) and DT identifies APSc lens.
Nikon uses FX (FF), DX (APSc) and CX (1-series)
Canon uses EF (FF), EF-S (APSc) and EF-M (Mirrorless).
This 12mm f/2 looks like an intriguing ultra wide option.
