When I saw this...
I went into this place.
It's the Penang Khoo Kongsi.I'm just a normal person. I don't speak proper English. I even don't write proper English. So, you may need to forgive me, if you do find my blog is annoying.
I am not a fan of filters. I don't understand what a filter can do since the lenses are coated already? The only one thing that filters are useful is to protect the lenses from knocking by others. So, when one day on a shooting day, so no luck someone knock onto the lens, and the first thing to break is the filter, but not the lens.
And then, raised one question: how low quality the filter has to be so when the knocking incident happen and I will not be heart breaking? Once I got one super cheap Taiwan made UV filter which came free when I bought my first ever DSLR, the legendary Sony A100. The filter is so thick that it creates a noticeable vignetting effect to all my photos, and thin filters are not cheap though. Breaking a RM 100++ filters are as heart broken as breaking a RM 1,000++ lens.
Another question raised: I was told by others in order not to get fungus to for the lens, the lens need to be exposed to UV light from the Sun so to kill all the fungus. So, with a UV filter on, will the UV light from the sun kill the fungus?
