Whilst testing the new Mobius Maxi, I thought it would be interesting to install the fast F1.5 lens B from the Maxi onto a Mobius 1, and compare it to the F2.0 C2 lens which is possibly the one most often used for dashcam purposes.
The first thing to notice is the different Field of View. The C2 FOV is wider than the B. In my car that means the corners of the A pillar are visible in the C2 video, but not in the B video. Whilst some may prefer to have as much of the road in view as possible, others may feel that the C2 is too wide. In previous testing I found that the FOV on the Maxi B is very similar to the FOV on the Maxi A (which is identical to the Mobius 1 Lens D). The downside of Lens D for dashcam use is the slower F2.8 aperture, with poorer quality video at night and in low light.
Apologies for the varifocal lens on another Mobius which intrudes into the FOV for the C2 lens

Looking at the FOV when parked, the C2 picks up more of adjacent parked cars, whilst objects in the Maxi B scene appear larger and better defined.

If you have a Mobius 1 with C2 lens and want a narrower FOV, but don't want to use the slower F2.8 lens D, then the Maxi lens B may be a suitable option. NOTE: The Maxi B lens is not yet available to purchase separately.
