I have been using polarizing filters for years, mostly 72mm on the 15-85. Recently I bought a 6D kit that came with a 77mm CPL. No idea what brand it was, all it said is "made in China". I put it on the Sigma 120-400. The quality went down, at 400mm it is poor. Then I remembered that many years ago when I did not have my current experience, I got a Vivitar brand CPL, probably for a UWA lens, and never used it. I put it on. It was beyond poor. It was just plain blurry, even though the AF worked.

I knew that a good quality filters is a must. In fact, all my other filters, clear or CPL, are by Hoya or B&W, and I have seen no noticeable IQ degradation. I guess I have to pay more attention to "free" stuff like filters...

I'm often asked by friends to provide advice on camera purchases. Often they send a link to an amazon or other online retailer that includes a package of the body, lens along with filters, cleaning kit, closeup filters etc. Its difficult to make them understand that free stuff that hurts image quality isnt a god thing. Almost all of those free add ons are total junk.

Not paying over a thousand dollars on a quality lens to put on a fifty bucks cheap glass in front of it. So no filter for me thank you. :D

Just bought the 135 2.0 couple of days before the Christmas and when the salesman asked me if I wanted to get a filter? When I said no he asked why and when I told him the exact same words he looked at me like I was committing some kind of a sin lol. :lol:

Since there have been a lot of discussions on filters/no filters, I did test mine, and did not notice any difference. Again, they are expensive filters. In real life, though, there were cases when I had to take filters off. But I never expected crap like that to come from B&H.

I spent thousands on quality filters, i know that i don't want to lose IQ with lenses and filters to be use with, i feel lucky that i went from cheapo to expensive high quality filters and i never look back.

Well, sometimes you can get quality filters from 3rd party if you know where to find, and China is able to produce many items of high quality at lower prices if they want, for example i saw that filter comparison of 10 stop ND, and they were comparing Lee Big Stopper with Haida 10 stops ND and Hitech, and the test shows that Haida was the best out of 3 and it is cheaper than LEE, i bought LEE Big Stopper before i know about that Haida, now i bought Haida i don't know if i should sell LEE BS.

Also i bought 3 GND glass filters, they don't have a big brand name, and honestly speaking, they were expensive, but they are better than LEE and Hitech resin GND filters i have, i can imagine if LEE and Hitech have glass GND filters of same sizes and stops, they may be about double of the price than that 3rd party one.

I started to look around of big names and alternatives, and i now only go with glass filters as i know i can get the best IQ, i placed 3 glasses filters in front of my TS-E 24II and the quality was still amazing, in fact even if IQ is low but i didn't see lose in quality or sharpness and at the end i've got results i dreamed about which is the purpose of use filters.

I found this out as well. When I bought my rebel xti with kit lens I also picked up one of those DSLR starter packages with the Canon Bag, Filter and 1GB CF card so in the interest of protecting the kit glass (laugh..I know...) I put the UV Filter on right away...I thought the pictures were ok but chocked it up to my inexperience. Several months after getting the camera I had it up on a tripod and it got tipped over. Not sure if it was the dog chasing the cat, cat chasing the dog, or whatever but the front cap and filter broke. After cleaning the lens and shaking it make sure there wasn't anything broken inside I started shooting with it again and the pictures looked better than new. Those cheapo filters really kill things. Since then I've started looking around at more expensive filters. :)

I bought a set of the Polaroid filters when I was on a road trip, not because I buy cheap gear but it was the only thing that the store had on hand. I tend to shoot into the sun a lot, and it was instantly clear that there were major problems. It wasn't a matter of just managing flare, but rather weird purple spots all over the place.

I threw them away - it was far preferrable to shoot a bare lens than use cheap filters in this case.

Heya,

I'm pretty sure everyone has tried a cheap filter at some point.

And learned how much of a waste of time & money it is.

It just makes no sense to put low quality plastic/plexiglass/gla​ss in front of your high quality lens and expect it to be fine.

Very best,

Very best,

I've been in photography for more than 40 years as a serious enthusiast and professional. I have never dropped a camera/lens or damaged a front element. The only filter I have ever used is a circular polarizing filter to reduce flare and reflection and to darken blue skies. I do use black filters and lens hoods regularily but never UV or protective filters.

I guess I'm missing something but, I don't understand the need for a protective filter, cheap or expensive.
Maybe I'm lucky but to spend thousands of dollars on expensive filters rather than buying a new lens doesn't make sense to me.

Actually, we were talking about bad polarizes, not protective filters. Everybody here knows about problems with cheap "protective" filters, I just did not know that polarized can have such huge negative impact on the IQ.

Sure thing....many of the responses were discussing filters but hey, what do I know.

AFAIK, the LensTip test on CPL's is one of the better or possible only CPL test. I use the Marumi Super DHG CPL's and found them to be very good. Smooth skies, nice colors and very thin. Reasonably priced and rated #1 by the LensTip test.

Reasonably priced? how much it is for 82mm thread or 95mm size?

rated #1 by the LensTip test? So is it the best reference to build recommendation? and what if another link/site test gave #1 to another brand such as Hoya or B+W, who we should trust or follow? I can make a test and then pretend to give #1 to a certain name filter, honestly speaking, when 2-3 filters are very good it is really hard to put one as #1 by all tests or always, i have B+W and i always hear top high reviews about its quality, should i change that to this Marumi now because it is rated #1 from somewhere?

My first real camera the salesman must of seen me coming.
It was a canon t3i and I didn't know anything except I wanted to go to a camera that I could change the lens on.

I got sold on this POS camera accessory kit for a 150 bucks, I tried to call the company back up so I could send their crap back to them.
They would never answer their phone.
And in the old forum I seen they had taken out a ad here in POTN.

I have kept this to myself, because I don't like bashing companies.

But If I ever meet anyone from that company they better be prepared to get their ass chewed on and there 150 bucks worth of crap they sold me tossed in there lap for free.


I will make sure everyone there knows how they stuck it to a beginner..............​.
I got a tripod in that kit that maybe a midget piss ant could use, but in no way would it support a t3i with a nifty fifty on it..........

I guess this post is out of line.
