Fog

[ckhris]

My front camera lens is foggy. I have cleaned the outside and its still foggy.

google Blackvue lens fog and you'll find some how-to's on fixing that

That sound strange, if it was / is fog on the inside of the lens, or at the sensor you would thing prolonged use would "boil" it off.

haven't seen it in the 750 before but earlier models were a problem for this, something in an adhesive they used that was off gassing after a period of time and fogging up the inside of the lens, it's a 10 minute fix once it's pulled down

 

[ckhris]

Is it easy to get the focus back after pulling it? Wonder it this is gonna be an ongoing issue too.

 

[ckhris]

Ill take it apart tomorrow and clean it. Its very simple to do from watching vids

 

[jokiin]

if you take the lens base off the PCB you won't alter the focus setting

 

[kamkar]

Yeah if you can get at it, then unscrewing the lens + its base / mount will be optimal, then you dont have to worry about focus shifting as the base / mount will screw back against the PCB in the exact same place.

I dont see a video on how to take apart the 750s. Its different than the 400s posted

someone here pulled one down previously to fix a focus issue, might be some pics there

 

[ckhris]

I have it almost all apart. There is something holding on the end where the wifi illumination is. Ill look and see if I can find it here

Lens is soldered on. No screws on 750 to take it out

265.00 mistake

that's just a cover on the back to shield the EMI, you can remove that then unscrew the lens base from the PCB, or you can unscrew the lens but you will need refocus if you do it that way

Battery pack soldered
Top cover soldered

it's normal for those to be soldered on
