View Full Version : Yet another filter Q ...

I have a sigma 24-70 macro 2.4 lens, love it, however no IS and heavy lens is a bit of a curve, but I will get it.. And maybe a monopod along the way :)

Anyway the point and question... I have a hoya 82mm UV filter on it, I have found from my last vacation that a few of my daylight photos could have came out a lot better if I had a way to keep the camera a little more steady without lugging around a tripod (that is where the monopod comment from above came from) but also find harsh areas in the photo that could have been avoided with a simple CPL or ND filter... Depending on the shot.

So that being said, looking at just CPL for right now and find that hoyas 82 mm are over 200 -- not that the price is out of the budget, I just cannot justify spending it. So, the actual question finally (sorry I find it easier to answer a question after knowing a bit of the history :))... If I bought a different brand say Tiffen, and applied it over the hoya, could the two different glass manufactures degrade each other in anyway... Would it come out worse then if I was to put a Hoya CPL over the Hoya UV... Or would it be even best to remove any UV while using a CPL or ND??

Sorry if this has been asked, and sorry for such a newbie type questions, but hey... I am still a newbie at this whole photography thing :)!!

Thanks again.

You really dont need a UV and a CPL. Either one or other will do.

Your UV filter is actually doing nothing as far as the lens is concerned other than keeping dust/smears of the front element.

Stacking filters certainly will degrade the images as it tends to bring out the worst of each.

Don't stack filters. Unless you need the additive effect of several ND or close-up filters all you'll do is degrade the image. If you're using the polarizer, take the UV off. But the high price for the Hoya or B+W filters is because they're better quality (flatter glass, multicoated to reduce flare and light loss, sturdier construction) than the Tiffens. You might consider looking at a few other dealers though. There are a couple of vendors that are less expensive than most, but still considered reliable. One, IIRC, is Filters2go and the other's HVStar.

I just spit out tiffen as an example, not looking at them. I am one of the people who like a UV on at all times. Thanks for your tips however, I will remove whenever using a CPL!

I guess I do not even really need the UV either, I just get paranoid over every smudge/scratch that could get on the lens..

I know that a good lens filter is expensive, I just find 250 bucks a bit high for basically a pair of sunglasses for your lens...

But, it might be worth it if I will not end up with white sky's, shadows, and every other crappy thing to ruin your sunny day photos! Remember I am a newbie, so I need assistance from things like filters :p
