Which one of these UV filters are better?

Canon UV-1 58mm
or
Hoya Standard UV Filter 58mm

I have some extras and I realize these aren't high end filters but which one is better to hang onto?

Nobody has any comments.... maybe because they are both junk? Still which one is better?

I think Hoya is better if you get their highest quality filter. I think they're on par with Schott glass.

Either one may or may-not degrade image-quality.

Between the 2 you have, the Canon may be better quality. If you look at the Hoay Pro1 Digital, I think it is better. For a spare, I would probably keep the Canon.

Spend the extra cash to get B+W MRC.

I already have them both though, actually I have two of each. I'm not a pro I just want protection.

I wouldn't bother with either one. Get a multicoated filter, such as
Hoya HMC, Hoya S-HMC, or Hoya S-HMC Pro 1.

Or, even nicer, try B+W MRC filters. They have nicer (brass) mounts.

You will find that non-multicoated filters are more prone to flare
than are multicoated filters. If you have a nice lens, don't corrupt the
image quality with a poor filter.

But the Hoya I mentioned is coated on both sides though.

I'd go with the Hoya then.

Still, muticoating doesn't simply mean coating on both sides.
It means multiple layers of coatings to attenuate reflections
over a broad spectrum of visible wavelengths.

Popular Photography magazine states that there's no detectable difference between single and multi-coated filters. Single coatings are so effective that any theoretical advantage of multi-coating just doesn't show up when the filter is put to use in the real world.

So far as to which filter to keep, why not keep them both? They don't take up much room and you never know when you might need an extra one or might damage it beyond repair (such as salt spray that damages the coating). I doubt that Canon makes their own filters. I'm sure they buy them from Hoya or some other filter company and simply brand it with their name. If one filter is coated (single or multi) and the other isn't coated, consider throwing away the uncoated one.

Thank you for that info. I think people tend to get a little carried away with these UV filters a little....

Reminds me of a "monster cable" discussion I had on a chat board when buying my home theater. People spend hundreds on freaking CABLES for a stereo system... I got mine for $5 bucks and can't tell a difference.

I'm with you on the monster cable thing. Seems ridiculous to me, when
my speakers are certainly a far weaker link in the system. [Still sounds
pretty good though.]

I think filters are a different story, though, and you might ask yourself

why lens makers go to a lot of trouble to multicoat their lenses if it's irrelevant.
Canon's flagship portrait lens, the 85L f/1.2 mark II is said to have improved
coatings. Coatings seem to matter, and in fact, I suspect they explain the
slightly different color rendering in Canon's versus Sigma's lenses.

Here is a long thread you can read through, if you are interested:

It references this filter test:

For most people, I suspect going without any filter is the best choice.

Search this forum all day long, or just visit my home, and you will see that I am a big fan of Canon photo gear. For filters though, Canon offers pure junk. Never buy a Canon filter, as they are all (so far as I can tell) garbage meant to collect sucker consumer Dollars. Did I mention that you should never, ever buy a Canon filter? Ever! Friends don't let friends buy junk filters.

Buy a Hoya HMC filter, or go for the gusto, and buy a Hoya SMC, or Pro 1 filter. They don't get any better than the high end Hoya glass, but if you are into serious Teutonic self abuse, you might consider the B+W multicoated line. They are stupid expensive, and B+W multicoating is limited to certain models, and is behind the industry curve a bit, but they are fine filters anyway. If that floats your boat, go for it.

Even with a pretty open budget, I will take a Hoya Pro 1 filter over anything else offered. Hoya high end CP filters are the best in the world by any standard, as they use Hoya patented glass polarizer technology that is not only tops in performance, but maintains an entirely glass sandwich, and doesn't incorporate a plastic polarizing element in the middle.

Whatever you buy, buy good filters, and avoid cheap junk. If it's cheap, it's junk. I don't care if you subscribe to my filter theory, and place Hoya at the top of the heap, or if you subscribe to the "German made is best, no matter what theory), and only buy B+W filters. The high end of both brands are fine beyond argument, and they will serve you well.

Just don't buy cheap Canon filters to screw onto your expensive Canon glass. That would be a terrible thing.....
