Ugh... bought a new Hoya HMC UV filter 67mm and only noticed there were small bits of coating marks on the glass when i reached home.

Anyone with similar experience on how this affects image quality?

1. is the coating mark in dead center of the filter?
2. do you often shoot at above F5.6?

if both answer is No, then it is not an issue.
if either one is Yes, then you 'might' notice softness or marks on your photo.

1. Not in dead center, but there are some bits (less than 5mm) here and there spread out..

2. Yes especially landscape/scenery shots.

Arggg I didn't see any of those marks at the shop when inspecting. This is frustrating...

Recently purchased a Hoya HMC filter... but I see there are many fine dots on the filter itself. Is it a defect?

Tried to clean it using microfiber cloth, but still can't remove it.

Quite common with Hoya UV filters, I had a few and also exchanged a few but am never happy with their quality. Stopped using Hoya from then on...
