Where is that filter group buy thread?

lol, look around Gear and Equipment, it's not too far away from this thread.

Thanks for this link! I've been looking for reports on filters for a while.

Funny how Hoya makes the best and worst filters. The other Canon forum (POTN) has many reports of poor image quality after using the entry-level Hoyas.

Hoya polarizers aren't as good as others, even the HD series shows up at number 6 in this website's test

this makes me think b+w did a great job wit their marketing

Hmm, but if you're using UV filters as lens protectors (which a fair bit of us do I think), I would think Hoya HD should top that list. We need a tested till destruction test for lens protection. =p

Why don't we just use a cheap UV filter and break out the glass? I would think it highly unlikely that if you drop your camera and it hits the UV filter that the object your hitting would be pointy enough to hit the glass of your lens as well. Luckily I've never dropped a camera or lens ... knock on wood.

Thick plastic wrap held on with an elastic band
I think also there is more to filter quality than total
light transmission. I have seen glass fall out of cheap filter
when the retainer ring comes apart. It is also nice trying
to tightly grip a $2500.00 lens (without damaging it)
while trying to remove a stuck (cheap) filter.
The brass filters always seem to out perform in the install/remove
department. Also the test mentioned above does not measure distortion
due to thickness variations in the glass.
I don't go for the top line, but try to get the brass, not alloy
filters and sofar so good
But would I spend $90.00 on a B/W for my 50mm f1.8 canon lens.
Not likely. But a B/W goes in front of my 80-200 f 2.8 or
my 24 -70 f 2.8 when needed.

In the past I've mostly used the Hoya S-HMC filters, however I picked up a Hoya HD UV and C-Pol filter in the last maxsaver buy. The durability is a plus, but mostly the idea of them being easy to wipe clean appealed.
I was thinking about doing a test to destruction of one of the Hoya HD filters, but at $30 for the cheapest one, I just couldn't justify it.

I haven't had a chance to try with more stubborn material (shooting in chalky climbing gyms in the past has been an absolute pain to clean) but fingerprints do seem easier to remove than the standard ones.

I do plan on doing a visual reflection comparison between:
- Hoya HD
- Hoya S-HMC
- Sigma DG
- Hoya Green box (got this one for free with a lens. I believe it is the "G series" one that did so poorly in the test)

I'll hopefully have a chance this weekend to do that.

Browsing around the site, I found a supplement to the original test, where they add the Hoya HD UV filter.

Spoiler: it would have taken third place, beating the B+W.

Unless you are above 4KM altitude the UV function of a filter is useless and higher then that it may or may not help depending on many other factors so the only reason to put one on your camera is to protect your lens. Except maybe for the Leica M8 do you think the manufactures don't consider uv and ir when they design a lense or camera?

After getting a hoya polarizer stuck a couple of times in the middle of winter I would never buy another unless they changed to a brass holder.

I don't believe in any UV filters for my lenses. For protection I use the lens hood, but that's just me.
