Is this serious? What should I do?
Thanks for your help by the way!!
I found this scratch on my lens, and I didn't know what caused it. It doesn't seem to affect the photo, but would there be any problems in the future? I'm new to cameras, so I don't know what to do with this...
Furthermore, I came to photograph a stream today, and suddenly it rained. I tried to keep my camera away, but water still leaked in. Thus, the first few drops of rain also made the camera somewhat wet. I've briefly dried the camera and the lens using some tissues, and currently drying it in a room with a fan and an air conditioner on "dry" mode. Would this help drying it? I don't have any silica gels, or oatmeal as my friend told me to. The images were blurrier afterwards, and also the focus seemed worse.
What is happening to the camera and the lens?
