Cokin BPW400 Filter Holder, P Series, Wide Angle

Picked up this holder for use with my canon 10-22mm. Works much better then the P multi holder. Must use the Cokin Polorizer and not a screw on type as that pushes everything out and creates a vignette.

I got this filter holder for my Nikon D90 to use when I am using my great Tokina 11-16mm really wide-angle lens. Unfortunately, I still get vignetting when using this holder. It works fine in terms of holding my square (actually rectangular) filters of the Cokin P-series size. To avoid vignetting I took the holder off the lens and actually held the filter right up against the filter. Got some great shots of my finger. Ok, I did manage to get some ok shots without my fingers blocking the lens, but it was difficult.The other understandable drawback from this holder is that it will only hold one filter; precisely to avoid vignetting when more than one filter is used. Other wise it is fine; not the worlds greatest construction, in my opinion, but certainly good enough.I did give it four stars as it does its job on lens with not quite so wide an opening. It worked fine on my 18-200mm lens.Btw, I like the Cokin holders, especially the one that holds three filters, but I don't use Cokin filters themselves. The HiTech filters are still fairly inexpensive, as filters go, and work good enough for me and better than the Cokin ones. Use of the filters, like the neutral density gradient ones, really make shooting fun and better when you have a light sky against a much darker ground. Give filters a shot if you have never tried them. It will make you a better photographer. Do get some basic instruction on using filters, even if it is just a half hour of advice from a friend.Nick

This is a well made product that does exactly what it's supposed to do. I use it on a Nikon 18-105 and a Sigma 10-20 with no apparent vignetting.

I brought this filter holder to use on my D90 + Tokina 11-16/2.8.It's something that cut two of the three slots of a regular P series filter holder, and it only hold one filter. There is no adaptor ring come with the holder, so you have to prepare one yourself. Build quality is solid, but don't expect too much.I just received the package and did simple test. On 11-12mm, obvious vegnetting, especially on 11mm since the four corners are totally dark. On 13mm and above, hard to find vegnetting. In my opinion, it's completely safe to use it on 16mm and above on DX format. Acceptable on 13-15mm. For those who intend to use it on FF format, you can calculate the equivalent focus.Hope my review helpful.

No problems. Unit was purchased to cover an 18-mm Nikon DX lens. No shadows or vignette at any lens opening. (Note that a DX lens has a narrower viewing angle than an FX lens -- don't know if the FX would be covered or not)

This is essentially the same as the standard ring but is a little closer to the lens. It only allows for one filter and doesn't allow the polarizer and one filter.

Holder is almost perfect for 12mm ultra wide, but nothing below 10mm vignette at 12 mm is considerable...so shoot at 13mm and it’s gone...good original product..I’m happy with purchase.

So glad to have the low profile frame available. I have a substantial investment in filters that fit the P-series frame so starting over with the larger frame series to accommodate my lens with 77mm lens thread was not an option. One suggestion to anyone just starting with the Cokin frames--buy the Cokin brand adapter ring. I tried an off-brand and found that the flange was thinner than the Cokin brand and did not provide the correct tension, allowing the frame to swing around loosely.REVISED 10/3/13: There is a snag with this new frame--Singh-Ray Polarizers for Cokin frame will not work because the concave curvature of the regular P-series frame is missing on this low-profile version. The convex curvature of this low-profile version blocks you from touching the edge of the S-R polarizer and being able to rotate it within the frame.
