:rolleyes: Some progress has been made after all these pages!
Those who advocate routine use of the 'protective' filters are now apparently agreeing that they also need to use hoods and pricey multicoated filters.

With repetition, enough repetition, acceptance will be inevitable? Nice try!
I do NOT advocate against or for the use of filters for protection. IMHO a UV (etc.) filter adds valuable protection, at very little cost in terms of quality to any optical system.
In summary, it seems that we've established that...
"We" ??? What's with this "We"???
(b) no amount of optics nor logic is going to affect decisions that have already been made...
Agreed.
