Here are some interesting zoom telephoto-vs-normal dash cam captures using the Mobius with this 6-22mm Varifocal ƒ/1.6 zoom compared to the FOV of the SG9665GC (112º).
In the following images, I set the zoom of the 6-22mm Varifocal to approximately 1/3 or maybe 3/4 of the potential zoom. The lens has no calibration markings so I can only guesstimate the actual focal length setting here but you get the idea. This is all experimental at this point, of course.
So, here are some recent screen captures of very nearly the same frame from the two different cameras. I've superimposed in green frames the actual FOV of the zoom telephoto varifocal as compared to the SG9665GC.
I would never wish to be without a traditional wide angle dash cam, but now that I've been playing around with CCTV varifocal lenses in a Mobius deployed as a second front facing camera for almost ten months, I think I wouldn't want to be without this capability.
Now that we have viable high quality dual channel dash cams, the chipset technology already exists to build a dual focal length front facing dash cam. All that needs to happen is to get rid of the cable and relocate the remote cam module to the front camera housing and engineer the best telephoto into it. Or it could be a base cam with a short cabled front facing telephoto with flexible positioning and aiming.
I predict such a product may yet come about.
