Think twice, see the result i posted. And you will use filter on the long run to protect front element of your lens, so stepping up or down is not recommended. You will try not to touch the filter as much as possible to avoid scratching the front element.

My 50mm f1.8 has no filter cause the normal Hoya which cost RM 30 is just bad. Hoya HD / B+w will cost almost half of the lens, i decided to leave it open smile.gif

I don't quite understand. Why is the shot of fluorescent light tube the determining factor for UV filter? Perhaps you can also explain a little bit more on the methodology of your test. What camera setting (exif of all shot would be nice), what white balance setting, etc. hmm.gif

i also don't know smile.gif it's a weird thing i pick up using different filter... no the images are not edited, just copy paste... might be my auto WB not working properly... but it's something i don't like seeing in my photos...

Youre using auto white balance? Maybe that explains the yellow cast. Perhaps the camera is adding some additional things into the equation. hmm.gif

It's not recommended to use CPL for indoors unless you want it specifically to cut some reflection on some surfaces. If you want protection then use UV. CPL more for outdoors. CPL as protection is overkill plus it cuts down on light.

If you want best IQ and you're shooting indoors with no obvious hazards then just remove all filters lor.

I always thought that no filter gives the best IQ. Apparently not from Vincent's study. No filter second last in terms of IQ.

1) Hoya HD
2) B+w (alloy)
3) Hoya Pro1
4) No filter <---------- see ... Very yellow. cry.gif
5) Hoya HMC

aiseh, tak ada Hoya HD ka... highest range of Hoya smile.gif

u can see from the test that some filters like Tiffen and King can really introduce more flare


Added on June 30, 2009, 10:39 am

hahaha, it was at night, my only source of light for flare is fluorescent smile.gif

i still don't get why one part of the tube was yellow and not both sides since the tube is round...

Maybe the shop in Poland dun have the HD. But what is interesting is that the Hoya HMC, the cheapest of the Hoya, is no different than the Digital Pro 1 with regard to IQ. shocking.gif doh.gif What is also interesting is that the Hoya HMC is rated last in your fluorescent tube test. hmm.gif whistling.gif
