Ok, so it probably doesn't affect image quality, but,
How clean can you clean the surface or a lens or filter?
Are you ever able to clean it to that pristine never-been-touched look for a mint lens?
Or even close?
I use a blower, followed by lens tissues with formula mc, but can never get it perfect.
Like, if you look at it, you can see some cleaning marks, you can see that it isn't perfect.
If I'm out, I'll use blower, breath on the lens, and a microfibre cloth, then followed by a blower.
Whether it is the lens or a filter, it's never pristine. There are some marks that just won't come out.
How do you clean? and can you clean it as good as, or close to brand new?
I know I should only clean the lens when it's really dirty, or if it affects images, but,
there's something irritating knowing that something is there.
It's like not washing your hands, a very disgusting feeling.
