Transparent protection filter
I'm looking for a very high quality transparent filter. I have been using a couple of different models from Hoya and one from Sony/Zeiss. Can anybody point me to a review/comparison or even better add some personal experience?
I'm personally very satisfied with the Sony, but where I am, it's difficult to find it; Hoya is more common, but I read that Hoya was acquired by a chinese brand last year and their quality is not as it used to be.
