How i focused my Mobius dash cam

[Gilbates]

This may or may not work for some of you but i found a successful way of focusing my Mobius lens C by simply using my Pc and a test image on my screen from the internet

i was not happy with the focus on the Mobius Lens C, its only 2 weeks old and has not yet been subjected to high heat but the focus at a distance just seemed slightly off... maybe it was me being fussy but i wanted the best i could get, i do not have a laptop to take out to the car and test with the Mobius plugged in, nor do i have the patience to move, fit,test over and over until it might or might not be slightly better, so i set about looking on the internet for a test image that might simulate distance for me to focus the mobius on.

doing this entails using the Mobius in web cam mode plugged in via its supplied data cable, the lens screw undone on the Mobius and an image from the internet, the image i used was THIS scroll down to image
Auto Focus Test 2
i held the Mobius about 3 feet away from the screen and using the freeware program amcap used this to preview the Mobius webcam image, i have 2 screens so i was able to put amcap on 1 screen with the Mobius webcam image and screen 2 had the test image, i simply adjusted the lens until i got the best image my eyes could see.

Today was a sunny day and using the Mobius the images appeared sharper than previous sunny day footage

I dont know why focusing on the image worked as i suspected focusing on a near object would probably mean out of focus far object but that didnt happen and i am happy to say my focus is now the best i have seen

Hope it helps others, it worked for me and saved a lot of trial and error focusing

Thanks for the tip, I've managed to refocus my Mobius C.
To do that, I winded the outer metal lens part round with a paper tape to get proper grip.
Then, after unscrewing the screw with a hex and assembling the camera back, I squeezed (really carefully) the mobius in vise and used a special clamp fitting the lens size just fine to move the lens. But I didn't get to tighten the clamp, because in the process I've realized that the lens was already turning by hand. So maybe the tape's roughness and this little gain in angular moment (larger diameter) let me apply required amount of force to move the lens.

As a result, the picture became sharper: before I did the refocusing, I couldn't have read little written text at the photo taken, and now I can. Didn't have a chance to make a proper test at daylight, though, and at night the license plates are reflecting too much.

UPD: Here is a sunny day:

Upper left corner looks much softer than everything else, I think that's the price you pay for the wide.
