>Filter experience needed

Okay. So I'm looking to buy some filters; circular polarizers and protection (expensive lenses). Amongst other things, I need a 77mm circular polarizer, and as you know, those are expensive with multi-coating. I've been trying to figure out whether a multi-coating is actually worth it. I don't have the filters to do the testing myself. How big of a deal is it? I use lens hoods.

>Also
Are there any negative IQ effects of using step-ups and big filters on a small lens?

With filters, you generally* get what you pay for. Multi-coated performs better, especially with internal dispersion from angles.

* except for lol thinnest filturr on the market hurr

Hehe. I found some pretty decent tests on most of the filters on the market, both UV and CPL. So I managed to find the best ones on eBay pretty cheaply. Actually got a 77mm CPL for 58$. Turns out Marumi makes good filters.

B+W filters are horrible, though. Not what you pay for.

multi gives you less reflections/ghosting if you've got light sources in the frame. like with a cheapo non-coated filter you can look at a lightbulb and see the extra images where you wouldn't without the filter.

Yeah. That's what I figured as well, after looking through quite a lot of tests. I also noticed there's a bit of difference between the multi-coated filters as well. B+W did pretty bad overall, as well as being costly. Hoya were mediocre, but cheap at CPL. They had the best UV filters. The best CPL filters were actually cheap Fujiyama and Marumi filters with multi-coating.

I just ended up going for multi-coated filters, but saved a lot of money on finding those tests.

Hoya HMC UV(c) filters are so cheap and good too.

The tests were a few years old, so those weren't in it. I haven't read about them. I found some new Hoya HMC UV(0) on eBay. They were the test winners, and pretty cheap, but aren't in a lot of stores anymore. I think the UV(C) only has a thinner frame. It's probably the same thing.

Here are the tests

I'm off to bed now. Check out those links for the next time you're buying filters.

If you're putting more glass on your lens something negative is happening. A polarizer is all you need with digital.

As for ghetto insurance, you're better off with just a lens hood unless you shoot near seawater or in dust storms or like the feeling of glass under your fingernails.

Don't even think about using more than one filter size. It will drive you insane.

Honestly, if you are serious about photography you will eventually wind up buying the bigger filters, so if you start there you won't have to throw away all the smaller ones.

I suggest using step-up rings and bringing all your smaller lenses up to the largest common size. For Nikon and Canon that would be 77mm.

For instance, instead of using 62mm filters on your 20mm f/2.8 AF or 72mm filters on your 28mm f/1.4D AF, just step them up to 77mm and never look back. Do you really want to buy and carry an additional dozen smaller filters instead of just a couple of step up rings?

This saves a lot of fiddling when you are out shooting and trying to swap filters around.

I suggest B+W brand German step up rings because they cost about the same as the crappy Japanese aluminum ones. They don't get stuck and have nice knurling to make them easy to grasp.

I buy multi-UV filters for every lens to have on at all times since it's likely I'm just going to be shooting without any other filter type on them.
I buy only one polarized filter and ND filter in the 77mm size and just get step-up filters for those lenses. This is for the occasion I may use them.

I guess you have not seen the lenstip.com review of UV filters. Spectrophotometer doesn't lie.

Don't own any step up rings but I do own a UV filter for my Voigtlander 35/1.4 which is made by B+W. Probably the best filter I have. Sounds like a fucking suppressor being attached to a gun while I'm screwing it in.
