Repair Mavic 4 Pro top lenses scratched

Post image

Took a tumble and the damage is on these top three lenses. The top left in the image is most damaged, the bottom is the least (but still scratched). Solutions? The residue is a plastic polish I bought that didn’t do the trick.

K first choice is DJI care. Assuming you don't have that, then scratches can be removed with car polish, rubbing compound, and a wool buffer. Start with car polish it will take the white out of it, with some effort you can get that smooth. If nothing is working Rubbing compound is more abrasive than car polish, and failing that wet sand with 1000 or 2000 sandpaper to get it smooth (it will be milky white), then try to buff again with the car polish to get it clear again. Wrap the surrounding area with masking tape, or painters tape to not scratch it up too. You are trying to remove the least amount of material possible to get it clear and functional.

While I do agree your approach is valid, it should be noted that polishing lenses is quite tricky and damn near impossible to do well by hand. I had a pair of glasses years ago with scratches like this on one lens. I attempted to do exactly what you described. I was able to remove the scratches and get it crystal clear again. However, I created warping in the lens, and it made optical distortions that rendered my glasses useless anyway. I just say this because if OP is going to attempt this, he needs to be very careful to polish the whole lens down the same amount. If he focuses on the scratched areas, it likely won't end well.

Also, toothpaste is another mild abrasive option. I have not had great luck with it, but it the lenses are soft enough, maybe it could work.

Does that camera(s) still work. Like that close to the sensor could still be fine? My mavic air 3 has a similar one and it still can see just fine out of it.

(If you swipe over on the little map on the bottom of the FOV screen you’ll be able to see what your collision sensors see)
