Re: What is Happening to My Lens?

Sunscreen can be gnarly stuff, but that looks far more easily visible than any coating damage I've ever seen before. I obviously can't know for sure, but I think it's residue.

I'd get in touch with a professional lens repairer. You can find a high-quality optical glass cleaner for non-water-soluble contaminants, pop the front element, and do it yourself, but if you've never disassembled and cleaned optics before, this ain't the best way to start IMO.

In the future, use a cheap-ish UV/protector a la Hoya HMC when near sunscreen and other hazmats in case the glass is exposed, and only clean optical glass of any kind with a quality microfiber cloth and distilled water (aka warm breath).
