Will Filters Fit My Lenses? When I am looking at different filters online, they usually have a mm number by them - like 77mm, 31mm, or something of that sort. Does this mean that the filter I am interested in buying might not match up with the lens I want to use it with? Or are they all universal sizes? Could someone explain to me how to find out what filters will fit over my lens?

On or near the front of your lens will the Ø symbol next to numbers like you've described. This gives the diameter of the screw threads on the front of the lens, given in millimeters (mm). Filters are sized to fit these. For example, if your lens has "Ø55mm", then you need to buy 55mm filters.

You can also buy individual resin filters that fit a specific holder. The holder, in turn, mounts to various sized lenses with the correct size mounting ring. Hitech, Lee, Cokin, Calumet, Sailwind, all make these rigs which, IMHO, work quite well and prevent you from buying and accumulating lots of filters of various sizes to work on different size lenses. Also, if your current lens is, say, 55mm diameter, remember that if you buy a larger filter - e.g., 75mm - you can get adapter rings to step it down to the smaller filter size, but you can't get a smaller filter to fit a larger lens. This is one of the major advantages to the resins I mentioned. Kind of a one size tends to fit most lenses with the proper size mounting ring. Take it light.

Welcome to BetterPhoto, Keith! The mm number for a lens filter does indeed have to match the mm diameter number of the lens (not to be confused with zoom). Jon already said how to find the diameter of your lens thread. Now, not all lenses are threaded. If it looks like you can screw something in front of your lens, it's threaded. Otherwise, either you can't buy filters or you need to buy an adapter from the camera manufacturer. Contact the company your camera is from and you can ask them about getting filters for your specific camera. Ariel ScrattyPhotography ScrattyPhotography Blog

Alright, thanks a lot everyone, that answers all of my questions and them some. I'll definately look into the resin filters too cause I'm planning on purchasing a 12-24mm lense later on, sometime within the next 1-3 years and I'm guessing that is going to be a pretty wide lense. My lense is 55mm too, very interesting how everyone used that for their example lol. Thanks again.

I didn't use that as an example! By the way, my lens is 55mm threaded, too. :)

You didn't use anything for your example though lol. But I lied too, I must have read my lense wrong, it was a 58, but it doesn't matter. Thanks to you people I just made some purchases, thanks again for all your help :)

LOL! Keith, you said everyone used that for their example. I didn't! Because I didn't have an example! I actually was thinking of using an example with 55mm, but saw Mark and Jon already did. :) P.S. I have a 58mm wide-angle lens with a 58 to 55 converter. ;)

77? Didn't know they came that big, thought 72 was the highest. Anyways, I should be getting my acessories in the mail by monday. And Ariel, what I meant was, everyone who used an example lense size used 55 lol. If anyone wants to know what I got, here it is. http://www.ritzcamera.com/product/251490678.htm I do a lot of lanscape photography and I always had a problem with overexposed skies. If I didn't want a bright sky, the landscape would be really dark. Now I won't have to worry about that hehe.

How did those products work out? I'm also looking for nd filters. Maybe I'll get the same things as you except the 55mm adapter instead of the 58mm.
