Cokin P-Filter question

Discussion

I bought the Cokin P kit after a few people here told me it was the better choice over the threaded filters. I was shooting today and noticed that on my 10mm lens, when shooting at 10-12mm, the filter frame thing is in the picture. Did I buy the wrong kit or is that a problem with wide angle lenses? Thanks for the help guys.

Jon,

I think it would be possible for you to cut the 3rd holder slot off the filter and see if that works. I'm not sure at 10mm, its really wide.

The other solution is to look at the Cokin x-pro or z-pro series. They are much wider.

Jon - that's a limitation with the P-series. I have the same issue even at 12mm on my 12-24. A second holder can be modified as Mel suggested using a Dremel tool or something similar.

I have the P-series kit for my 17-40L lens on a full frame camera: (equal to about 11mm on your camera). I rarely shoot with it wide open at 17mm because it's just too wide for most shots and causes vignetting. Whether or not the frame is in your picture also depends on how large the filter threads are on the lens. 77mm is as large as I've seen lenses work with the P-series. If you had a 58mm kit lens I would think that this would not be a problem becaue the frame would be far enough outside the end of the lens.

yeh, I have the 10-22mm with a 77mm thread. Hmm...this is rather annoying.

Confession: I usually just hold my filters loosly against the end of the lens - no filter holder. Take care not to scratch it. This is quicker (my photojournalistic nature showing through) and avoids the situation with the filter holder. The only exception is when I'm doing serious work with the tripod.

Yeah, I thinks when you go wide enough to shoot your feet when standing behind the camera, you would be very hard pressed to use any filter.

That's a pretty wide angle lens for filter use. One thing you didn't mention: did you get the standard Cokin holder, or the "wide angle" version? The only difference is the standard holder has 3 filter slots, I believe, and the wide angle one has only one slot. Many people just cut off the outer two slots of the standard holder to avoid vignetting with wide angle lenses. I bought the wide angle version, which I believe is fairly new. It just saves you the trouble of cutting off the slots yourself.
Not sure what camera you're using, but at 10mm on full-frame, you're going to have problems with almost any filter, not just this one. At 10mm on a DSLR, that equals about 15-16mm full frame, which would still be a problem with most filters, I would imagine. As Ken said, you might have to hand-hold your filters against the lens instead of using the holder, if you plan to shoot that wide.

Thanks for the reply Brent. I am using the a Canon 30D and the canon 10-22mm EFS that is made for DSLRs. I will check out the wide angle version. Thanks so much!
