    Wideband CPL filters

    Hi all, I have been encouraged to purchase a CPL filter. Is someone able to tell me the difference between a Kenko Pro 1 & a Pro 1 Wideband. The one I am looking at is the Kenko 58mm Pro1 D Digital Wideband CPL Circular Polarizing C-PL W Filter.

    Filter.

    I have one of them Zeta CPLs.

    I got one because I wanted to see if there was any quality differences between it and a lower or mid range product.
    I wasn't going to pay the inflated prices even on the online grey retailers, but last year at the photo show in Melb, an offer too good to refuse came up and I got it.
    The reason it was at the high end was the 82mm diameter of the filter I needed(Tammy 24-70/2.8).

    I can't test it easily against my other polarizers due to all their size differences and me lacking filter adapters to secure them all.
    Hand holding them in front of a lens could introduce errors.

    But from what I can see in the quality of the filter itself, it's very high.

    I did have one unfortunate situation where I mounted it to the lens cap of the Sigma 12-24mm, and if you know the lens cap design of this thing, it'll make sense.
    But needless to say, it basically got stuck, and nothing I could do by hand would remove the Zeta from the lens cap holder.
    I had to use a pair of multigrips(actually plumbers wrench) to get a strong enough hold of the ring .. and in doing so I've battered and bruised the metal rings of the filter.
    But it still operates very smoothly and tightly even after this botch job.
    So (and an important factor) the build quality of the filter is up there with the best.

    I'm 99% sure that had this problem happened with one of my low - mid range hoyas, it'd have bent and broken the ring and loosened the rotating ring from the base ring.
