Back in the day, lens cleaning was a front and center concern, with everyone discussing their preferred methods and products. I had a blower brush, tissues, and fluid as part of my kit.
But now, nobody talks about it, and not only do I not need to clean lenses on a regular basis but I don't recall when I needed to clean them at all!
Where did all the dust go? Are newer lenses coated to repel dust rather than attract it like they used to? Is the air cleaner?
I'd especially like to hear from anyone using both vintage and new lenses on a regular basis, who would be in a position to notice a difference.
