Anyone ever tried Low Illumination CCTV Security Camera Lens F1.2 4mm on Mobius??

Has anybody actually done this, i.e. spent the money on these lenses and confirmed their superiority to stock ones?

The developer is meticulous about which lenses he uses and is constantly looking for the very best lenses that will fit the Mobius. The lenses used are not off-the-shelf items.
I very, very much doubt anyone will find a superior mass-produced lens with the same size as the stock lens. Individually produced lenses, maybe, but they'll cost many times more than the Mobius. Janke, from RCGroups, has evaluated a variety of different lenses but has not found anything superior to the lenses used in the Mobius. Most, if not all, can't match the Mobius lenses.
