@Dashmellow Could you start a new thread that explains what we should look for in aftermarket lenses? Although what you said above must make sense I can not take that information to figure out what kinds of lenses might work well or not. I have no idea why f stops and such matter or how to match any lens to a maxi. Although I took most of the yearbook pictures when I was in high school that was years ago and I only used the schools manual 35mm camera with just one lens.
I would assume the starlight lenses should provide a better night image. Why they should be better than stock I have no idea. A basic here is what we look for and why tutorial could help those of us who can only blindly follow another members success to perhaps make some good (or not quite so good as nothing is ever guaranteed) lens choices of our own. I would like better night vision but do not know how to decipher which lenses might provide that potential improvement. Of course, we are all flying blind as mobius does not provide its exact lens source or technical specifications.

@c4rc4mM12 lenses, originally designated “S Mount” have been around since long before dash cams and action cams came into existence. There are many different types of S mount lenses made for a wide range of tasks but these lenses have to be carefully matched in optical performance and lens dimensions to suit the particular camera they will be installed in.
Those of us here on DCT who have devoted a lot of time and effort engaging in actual HANDS ON experience with aftermarket M12 lenses have learned to evaluate the appropriate specifications when we purchase lenses. We look at BFL (back focal length) MBF (mechanical back focus), sometimes FFL (flange focal length.......as with the M12 varifocals) and other significant specifications such as resolving power (Megapixels), Of course, a key consideration in choosing a lens are the actual dimensions of the lens, such as width and barrel length before we make a purchase.
If you go on AliExpress and look at some of the lens offerings you'll see that most vendors not only provide all the necessary information required to make a purchasing decision for your specific needs but that a very helpful technical drawing with all the precise dimensions of the lens is usually on display.

Trial and error often plays a huge role when experimenting with M12 lenses. This is how all of us on DCT who have been experimenting with alternative dash cam lenses for several years now have learned what to look for when we evaluate M12 lenses for purchase.
