Cut down to size
I was just flicking through N-Photo issue 72 and was drawn to the Q&A about a recommended filter set for the Sigma 10-20mm f/3.5 lens. Having just bought the lens and having traded in my old Sigma 10-20mm f/4-5.6 I was a little dismayed to read that my Cokin P-Series filters would not work with my new toy! I didn’t want to throw down lots of money on a new set, so I decided to experiment a little. When I first bought my Cokin P-series starter kit I also bought a set of ring adaptors to fit my various lenses. Included in the set is an 82mm adaptor which I duly fitted to my P-series adaptor and 10-20mm lens. I found that I could get down to about 13mm before seeing the edge of the filter adaptor, so not great but acceptable.
However I read somewhere, years ago, about cutting down the P-series adaptor to one slot, which I did in about five minutes with a junior hacksaw. I then re-assembled the adaptors and attached it to the lens and found I could use it at 10mm with only minor vignetting in the corners, or 11mm with no vignetting at all. I’d have to live with only being able to use one filter with this set-up, but it doesn’t seem out of the question. So before everyone invests in a new filter system, try this, it may save you some money and reduce the amount of kit you have to carry around.
