    Just bought a Sigma 10-20mm. I bought an adapter ring to fit the 77mm lens for my cokin p-series filters.

    Anyway I notice the ND grads have more effect in the top corners. I assume this is because of the shape of the lens, being more fisheye.

    Is there any solution to this?

    Any advice much appreciated.

    Peter

    Yes you need a wide angle adaptor and Zpro filters or Lee.

    This is an often covered topic especially for this particular lens so have a search of the forums for all the options and suggestions, but in brief Andy is suggesting the best option (imho).

    I went with a lee system and wide angle adapter to be on the safe side for my Sigma 10-20, not cheap, but worth the money I think.

    if you stick with the P-series shoot at 12mm - it seems to avoid the worst of problems, or shoot in portrait format that works as well

    saving up for Z-pro or LEE system and suggest you do the same

    The problem with a wide angle adaptor is that you are restricted in the number of grads you can use (it may even just be one), so the only real solution is to move up to larger filters.

    However, there is an alternative - HDR.

    I recently bought a 10-20 but do not want to (can't afford to) buy larger filters for it, so whenever I use it I take HDR shots. If you check my portfolio, any shots you see which have been taken with that lens are HDR.

    I may buy larger filters at some time, but for now HDR does the trick for me.

    But you still need a wide angle adaptor and it has nothing to do with how many filters.

    Its used to hold the filter holder.

    Oh okay, I thought you were talking about the Cokin P series wide angle adaptor, which I think is just a single slot version of the standard filter holder.

    Re this quote from Ian.

    Perfectly true, I have found the same prob with Sigma 10-20 lens and Filters, but using AEB to take 3 RAW images and process on Photoshop CS2 cures the need for Filters.

    Then process on HDR Merge in Photoshop CS2 gives fantastic results. Still needs sorting in Level, Shadow Highlight, Brightness Contrast and Smart Sharp, result with experiment. Brill.

    So far not tested on publishing photo but experimented on various and brill.

    Try

    Agree with Andy's suggestion. Even with Lee you can still sometimes get cignetting in the corner if you have a grad on an angle - at 10mm - with UV filter. So my advice would be to remove the UV filter (if you are using one).
