Cokin filters on Sigma 14mm f/2.8?

Discussion in 'Accessories' started by tklancer, Sep 8, 2004.

  1. So, I've got a Sigma 14mm lens -- the kind with no filter screws on
    front and a built-in lens hood. I love the lens, but I'd like to be
    able to shoot landscapes with a grad ND filter on it. Are there any
    tools out there to hold a cokin P-type filter in place on this lens?
    Has anyone made a custom filter holder? I'm not entirely sure a plain
    P-type filter will cover the entire field of view (though, I'm using
    the lens on a 10D, so that may help) -- is there anyplace I could get
    larger graduated filters?

    Any help would be most appreciated, thanks.

    I have seen a filter holder, sold by Cokin, for point and shoots that the holder is attached to the tripod mount of the camera. Mind you, it was the smaller filter type, not the larger P that I think you would need.
     
  3. Have you considered 2 dabs of Blu-tack on the filter and stick it to the lens hood? I've no idea though, as you say, whether the filter is physically wide enough.

    Another alternative is digital post processing to merge photos together and add dynamic range. I've been doing some of this in Photoshop 5.0 LE and it's worked well for me. Here's a couple articles that were of use to me...

    Hope this helps!

  5. I've got the Sigma 14mm f3.5 on *istD. I'M nearly able to shoot with the metal rim holding the lenscap still placed over the built in lenshood. So my advice would be cut some ring from black cardboard for a first test and build a second version fom black painted metal with some velvet glued in and attach the Cokin to it.
