I just bought a Xiaoyi (a cheap GoPro style POV camera made by Xiaomi), and after removing the protective lens sticker I found the lens to have a spot on/in it. It's either an air bubble or fungus, but I'm not sure which, or even whether it is a serious/uncommon enough issue with a camera to warrant demanding a replacement.
The bubble like spot appears to the top left of the lens. It is definitely not a reflection of any sort. It has an irregular shape and has a fixed position relative to the lens/camera. It has remained even after cleaning with microfiber cloth that I use to clean my DSLR lens.
Also, I'm not able to ascertain whether it is affecting my image quality. The only issues are flaring when pointed towards a light source, but I cannot confirm whether it is being caused by the said defect.
Even having Googled a lot, I've been unable to find a similar looking defect on anyone else's lens (on any camera).
Can someone please confirm what the wierd spot on the lens is? (Please see attached images). And whether it will potentially affect image/video quality? And how I can perhaps definitively confirm what kind of effect the spot is having on my images?
Thanks a lot.
