I have a new lens and I have some dust on the edges of the front element that probably don’t effect on image quality. I’m using now a protecting filter to avoid dust on lens.
How often should I clean the front element of the lens? Is it okay to leave the dust there and clean like once a year or will leaving the dust there do some harm to the lens?
