Carbon black was and still is the best lens cleaning substance ever used. Carbon black (ultra fine powder) acts like activated charcoal and a mild abrasive that is way too soft to hurt the coatings but will loosen and absorb almost any gook. It will lift oils and other stains that you can't get o

It might help a little bit in situations where the light coming almost sideways that would normally hit the front element is now blocked by the ring on the filter, but then why not just get a good lens hood? Todd At 01:29 PM 4/17/01 -0400, you wrote: >Let's say I mount a top-end multicoated (B+

The filter added to a single-coated lens, will not improve flare resistance. The lens must be considered separately from the filter. The flare of the lens will remain unchanged with or without the filter. The flare from the filter will be less (probably) than a single-coated or un-coated fil
