I was just wondering, what to do if certain things happen to the lens. I was taking macro pictures of water, today, and I got a few drops on the lense. Should I just let it dry? Or do I need to do something about it? Also, I heard fingerprints can be bad for the lens too. What should I do if I get a really small one? Is it safe to leave it if you can't see anything when the picture turns out? Thanks for any help!!!
