The Mobius C Lens was sent to me by GearBest to test and review. While the Mobius C has the new V3 PCB that improves charge time and over-voltage protection and also has the 820mAh battery that gives around 2 hours of runtime, the main difference of this model is the lens, so rather than review the whole camera again, I would prefer to discuss and show the differences to my A lens.
The Mobius now has 3 different lens choices, with different FOVs:
The A Lens field of view (approx.): 86 degrees (1080p)
The B Lens field of view (approx.): 116 degrees (1080p)
The C Lens field of view (approx.): 131 degrees (1080p)
The big improvement of the new C lens, is that it is has noticeably better brightness across the entire frame and has extremely better flare reduction when compared to the B lens. That brightness is very noticeable at night time and I that find night recordings are much brighter than my A lens. That brightness on sunny day recordings can make videos look slight over exposed and I expect some improvements to come from the developer to improve the exposure settings of the C lens setting.
The main disadvantage is the change from a metal to FRP composite lens module. It appears from reports that refocusing the C lens is very difficult because the set screw can dimple the adjustment screw on the lens, making it almost impossible to turn without tools and damage. Some reports here have also claimed that the focus changes when the camera gets hot. In my test, so far, I have not been able to reproduce it and further testing is necessary when the weather is warmer or possibly warming the camera with a hair dryer.

As you can see each FOV has its advantages. Narrow lenses like the A are great because reading number plates numbers is easier and the view is more accurate to what your eyes see in real life. Wide lenses can capture so much more side to side and let more light in at night, though that close call you just filmed, doesn't look so close when filmed on a wide angle lens. Wanting the best of both, I have the C lens and A lens mounted side by side as my full time setup.

So far, after a month, the C lens is performing well and is a good addition to the Mobius line, the video is sharp, their is no flare nor vignetting like on the B lens, the color accuracy is better than the A and night performance is great. I will do some more heat testing to see if there is any focus shift as well as some night videos using the different WDR settings to maximize low light performance. Here's the link to the camera
