i did a quick comparison lately when my friend drop by. I try to get the similar angle, sorry didn't use tripod, but i think it's pretty accurate. Result were consistent even though i change angle



guess which is which

quite obvious there are couple of images, and i also asked which is which filter and i also mention comparison... so in short, different filters were used for each images to prove differences in filter.

here's the filter used



conclusion, rank of filters

1) Hoya HD
2) B+w (alloy)
3) Hoya Pro1
4) No filter
5) Hoya HMC

the ranks also correspond to the price paid i believe...

Equipment used is Canon 40D + Canon 70-200mm F2.8 IS L

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

if u think it's flaw, then it's flaws

if u think i cheat, then i cheat

nothing i want to defend and rather nothing i want to explain cause i understand LYN too well.

I'm believing what i'm seeing. I'm only getting B+W and Hoya HD filters for all my future lenses... if you are not believing it, i'm not forcing u to believe it

the test was what i think is simple, screw in the filter, shoot something. Ppl in LYN will argue day until night why don't u shoot something else... why use canon and not nikon, why use auto WB, why use 70-200 f2.8 IS and not any other lens... why don't use tripod... i don't think i wanna go about explaining that.

As i say, it's a simple test, my friend came over to test out some lenses, i grab wat i have and use the normal setting i normally use and shoot. The only difference are filters used. I took the image with this '\' angle, i also took the image with '/' angle.

I don't work for Hoya, B+w or Canon, i don't really care if u think it's flaws/cheat or watever u call it i believe wat i see... and i'm sharing wat i see... i won't spend too much time doing another test too to prove i'm right as i say, i don't care if i'm wrong

HiroBoroi: no the post is not against u... hope u don't get offended... cheers

i also don't know 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...

I check the EXIF, shutter speed is 1/1600. I shoot at different angle too... and it's consistent

it could be flickering, but it should be on both sides... See that Pro1 and B+w has some yellow / brownish only on the bottom right side of the photo and not on the left side of the photo. It's a round tube, it's not possible to have it on one side and not the other.

Hoya HD is clean however i shoot it... i first thought it was the angle... i shoot -, /, \, |... all same on HD, no yellowish...

i even clean the lens and filter thinking it could be some oil

some of the point to note
1) how often do u have time to figure out how to fix the problem when you have an event going on?
2) is angle the problem ? Hoya HD has not have such issue. B+w only has some yellowish on this photo and shows none on other angles.
3) if it's flickering, how come it's not both sides since the tube is round
4) why yellow? i don't know hahahaha
5) is that something u'll be happy to see on ur photos? yes and no... in my case, i would say no...

no hassle, Hoya HD or B+W only, I don't have Pro1 with me now, it was my friend one, y don't u guys try it ? Hoya and B+w might be paying me under table, who knows... hahahahaha.. u guys try it out and share ur results

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

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 amhahaha, it was at night, my only source of light for flare is fluorescent

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