TextFields and FieldOfView

Would it be possible to expand the available TextFields in Rhino 7/8 to include “exotic features” such as DetailLens (24mm/50mm etc) and DetailFOV (75deg/40deg etc)? It would be great for Storyboards etc.
Clear Explanation

Using the “stock lenses” from 3dsmax (any version) as an example, you can translate the Lens to FOV (Field Of View) as follows: Lens: 15mm = FOV: 100.389deg + Lens: 20mm = FOV: 83.974deg + Lens: 24mm = FOV: 73.740deg + Lens: 28mm = FOV: 65.470deg + Lens: 35mm = FOV: 54.432deg + Lens: 50mm = FOV: 39.598deg + Lens: 85mm = FOV: 23.913deg + Lens: 135mm = FOV: 15.189deg + Lens: 200mm = FOV: 10.286deg. Theese are just a few standard examples that any user of Rhino 7/8 would benefit from having easy access to specify directly in the Properties Panel (Viewport/Camera) in Rhino. Clear Explanation

Using the “reverse calculation” from 3dsmax (any version) as an example, you can translate the FOV (Field Of View) to Lens as follows: FOV: 15deg = Lens: 136.724mm + FOV: 30deg = Lens: 67.177mm + FOV: 45deg = Lens: 43.456mm + FOV: 60deg = Lens: 31.177mm + FOV: 75deg = Lens: 23.458mm + FOV: 90deg = Lens: 18.000mm. We need to be able to specify Lens or FOV to match with fx Enscape. Clear Explanation
