had quite a bit of a nightmare cleaning my filter just now.
There was a fingerprint on it and so i tried using a microfiber cloth to wipe it off. Ended up making the fingerprint into a smudge.
Decided to try using the lens solution provided in the cleaning kit together with the microfiber cloth. same result. The solution probably left streaks there as well.
Then went to use lens tissue...fortunately it helped to clear up most of the mess on the filter.
What methods do you guys use?
Sometimes i wonder does the ease of cleaning depend on the filter itself? The one i tried to clean was a cheap Massa multi-coated UV filter. I wouldn't mind spending on a better filter like Hoya HMC ones as long as they're easy to clean
