Protective filter… or not? I say beware of filter quality.

Case closed: use it if the QP of your filter is high!

Those pics were taken with my A77, and my Minolta 28-105mm RS lens. I took two shots per filter, and used the best of each.

Tripod was used I guess?

Even at 100%, its tough to see the difference between the No filter and the VF62MPAM. (I incorrectly listed it as a CPAM)

Here you tend to confirm my post above, since it depends of the combo lens/filter used (since I noticed it's very picky between the choice of two copy of the same lens w/ VS w/o), the only thing left for us is to try on, imho... BUT: as you wrote, no visible difference with an excellent filter VS without, so why not mounting a filter with a walkaround lens?!? (And more).

OTOH it  seems to be you don't tried in such light situations which these filters are made for (faulty lens haze nor UV colour cast...). I regret it, but it's a good news as well, since that proves the lack of harmfullness in a "normal lighting situation".

I think the case can be closed like this: "evaluation of benefit/risk depending of the way we use (and we care of) our gear".

The Quantaray Pro Digital is also very good. The Quantaray DMC-UV filter is not looking too good, but that filter was probably sitting on the store shelves for decades.

It's a known fact that old or cheap coatings sucks VS highest Quality Products (QP) and dedicated to the digital era...
