Be thankful. My collection has 48, 52, 55, 58, 67 and 77 mm diameters.


Why does the size change with the different lenses? The 2 I now have are the same.


If you're talking UV filter that you want on the lens all time, obviously stay with 52mm.
If you're talking CP or ND filters and have plans to upgrade to better glass with larger diameters, you would want to consider high quality filters of a larger diameter like 77mm. Step down rings are cheap, nice filters are not.

Am I understanding that you are saying that "better glass" has the larger diameter's?

Also, how do I know which filters are higher quality?

Are there different quality filters for each size?

As a general rule the more expensive the lens, the larger the diameter (to let in more light). Look at your kit lenses (the ones that came with the camera and are fairly inexpensive as lenses go) and compare those (beer can diameter) to the mini-telescopes (frying pan diameter and quite expen$ive) that pro sport shooters have on the sidelines. The pro shooters have those huge diameter lenses so that they let in more light, to have lower ISO (better color quality, less noise), faster shutter speeds (to freeze the action), and wider aperture (to blur backgrounds and isolate the subject which will be in sharp focus). If this doesn't make sense yet, it will soon as you learn more.

Some lenses have large front elements because of their nature. My 10-22 Ultra Wide Angle lens is 77mm, and my 100-400 Telephoto is also. Other 'middle of the road' lenses usually hover in the 58-67mm size. Like telescopes, the larger the front element, the better the light gathering ability. If you look at the big white Canons in use at any sporting event, you'll see some whacking great big front elements.

In the mid-range consumer lens, it's not so necessary, and also, much less expensive. A 77mm front element is nearly twice the actual size of a 58mm front element. That stuff ain't cheap.

Picture worth a thousand words?

The short version is the more expensive filters are better. If you stick with known name brands like (in order of quality good to better) Tiffen, Hoya, B&W, Heliopan, and Singh-Rah; you should be OK. If you have to speak Mandarin to say the manufacturers name, probably not a good idea.

If you are going to buy online stick with the big name stores like B&H and Adorama.

EricLPT speaks the truth. In most cases with name brand camera lenses, BIGGER=BETTER. Size matters.

They're not $12,000 lenses because of the aluminum casings.

The large fluorite elements in top-of-the-line lenses are actually GROWN from crystals and polished down.

(And yeah, I know, the fluorite is usually an internal element but I grabbed the first big pic I could find...)

Use what I use bunny-boy.. an ring adapter step up to your largest (77) and buy only one set of filters!
Step-ups are cheap $3,00 each 77 caps are also cheap $2,50

You can save tons of money and doing that, convert it in more burrow space for the next generation! :shock: :mrgreen:

Duct tape, man... Haven't you guys ever heard of duct tape? I got only one size filter, the super-size, and then I just duct tape it to the front of whatever camera someone will loan me. Problem solved.

Shoot, I just haul a big ol' piece of plexiglass around and prop it up in front of my tripod.
