Is it still possible to use the cokin p series filters with the sigma 10-20mm lens. I read somewhere that it wasn't and the shot would suffer from vignetting but the lens is 77mm and the filter measures rougly 82mm.


Any advice appreciated

Thanks in advance.

The picture isn't formed directly in front of the lens. It spreads out quite a lot to the sides too.

Here's an example at 16mm when I was playing with ND grad. Already you lose the edges. It will be a lot worse at 10mm.

Would holding the filters against the lens without the holder in place elimate this? I have also read of a wide angle holder with only one slot that also elimates this, only downside is that you can only apply one filter at a time.

You could hold it, although it probably wont be fun to do that. The slim holder might help somewhat, but I still don't think it's rated to 10mm.

I should add, this is with the holder in portrait orientation, thus limiting the horizontal width. If you're not using a directional filter, then if you put it in landscape orientation that would probably help. Snag is if you use NDs, you do need to slide them on the long axis.

I was interested in buying the Cokin P-series filters for my 10-20 a while ago but chose not to for this reason. However, when I was reading up I found that some people have gotten acceptable results with the 10-20 by sawing off the extra filter slots on the filter holder or by buying the slim holder (1 slot only I think).
