Can cheap filters damage your lens? A cautionary tale from Roger Cicala

Perhaps the title should be “Can Slim filters damage your lens?”.

Avoiding an el-cheapo deluxe generic filter on your high-grade lenses is excellent advice. But the article only finds tiny instance of budget “Slim” filter as the cause of front element damage.

Aren’t wide angle lenses the only ones that even require “slim” filters?

So for most other lenses it would follow that a reasonably priced multi-coated Hoya UV (non-slim mount) filter will pretty much do exactly the same thing as a $150 Heliopan or B&W UV.
