    Default Slim and Non slim CPL. What is the difference?

    Hi, i'm thinking of getting a CPL for my tamron 17-50mm lens. Must i get the slim version? Or can i save some $$ and get the non slim ones?

    slim CPLs are designed to reduce vignetting on ultra-wide lens like the sigma 10-20mm. on my tamron 17-50 i have been using a normal kenko CPL with no obvious vignetting

    You might also want to note that if you're going to leave the filter on your lens, nomal lens caps will not fit the slim filters.

    if you're going to stack filters (like a UV + ND + POL) u might want to get the slim version to reduce vignetting... helps a big deal for the wide angles...

    one I know of is Marumi... I got no problem attaching tianya ring and also my lens cap on top of the CPL... the CPL is as slim as normal Hoya UV.

    This I got to see. The reason for these filters is that their profile is slimer than the regular filters. Makes no sense to have threads unless they use thinner glass.

    I see what you mean now. If its for stacking then a few round of threads wouldn't thicken the profile too much. If you read my message again, I meant the clip on caps that comes with the lens. Those will fit?

    I already said in my last last post
    one I know of is Marumi... I got no problem attaching tianya ring and also my lens cap on top of the CPL... the CPL is as slim as normal Hoya UV.
    Im putting on the CPL as my "protection" filter instead of the UV, unless I need more light...

    ok another snappy shot

    Ok, the additional image makes it clearer now. So where do I get Marumi filters?

    I am actually ok with the provided cap by B+W slim filter though it caps on using "friction".

    Darn... I am also quite interested in the Marumi filters now... But I don't have a way to pay in ebay and I prefer to get it from a retailer... (And I cannot figure out which one is the slim version in that list of filters!!)

    I've got a hoya pro1 for my tele lens, and i can clip on the cap. So if i use a non slim cpl on my wide angle zoom, it'll be ok right?
