Disclaimer:
This thread is (hopefuly) about the difference between filter brands, not about whether or not you should use a filter. I am VERY aware and respect the fact that there are many folks who prefer not to slap a piece of glass in front of their awesome lenses. I get it. Ok. Respectfully, this thread does not apply to you.
I'm looking for a decent, clear protective filter. UV is not a major requirement for me, so if it is a UV filter or not is no deal breaker for me. My objective is to simply protect the front element of my lens so I won't have to worry about using a lens cap or lens hood. I recently scratched the front element of one of my favorite lenses (a lens hood would not have been able to protect it due to the way it got scratched) , so I am looking for clear protective filters for my other lenses.
Not a fan of slim profile filters ( I use EF lenses on my crop sensor Canon, so a thick filter won't cause any major vignetting issues), so paying extra for a slimmer filter is not my intent.
Seems there are fans who swear by their favorite brands (B+W, Heliopan, Hoya, Tiffen, Zeiss, etc). As expected, non-fans always find faults in the filters of brands they don't like. So, my question for those of you who have owned or tried out protective filters of different brands:
- Which filter is the clearest with the least amount of ghosting issues?
