Cokin CBP400A P-Series Holder

It does what it was made to do. Fit my Pentex K1000

i started using the cokin filter system many years ago with my minolta x-700 lenses. i've always found it easier to slip a filter or two into the holder rather than screwing/unscrewing filters from the lens. the holder is useless unless you buy the correct size adapter for your lens.the holder can take several filters at a time as well as cokins circular polarizing filter. i just leave a filter holder on each of the two lenses i have for my nikon d90. of course, this means buying a holder and an adapter for each lens. the adapter needs to be sized for the size of the lens but the filter holder part of the adapter is a standard size that fits the holder. so i have a 52mm and a 62mm p-series adapter with a holder for each. since i leave the holder/adpater on the lens all the time, i also had to buy the cokin p-series lens cover (a square, black piece of plastic that slides into the holder slot closest to the lens.) you could just buy one holder, then an adapter for each lens since the holder just slips on/off the adapter.the filter holder can rotate on the adapter, so that the filter orientation is easy to adjust.note that the p-series is for larger diameter lenses; the a-series is for smaller lenses. i don't remember the break-off point for using the p-series vs the a-series, but since i have both large and small diameter lenses i went withe p-series so all my filters can work with any lens size (having both a-size and p-size filters would be expensive and a pita). the cokin web site can give more info.disadvantages: looks weird on the lens; makes lens storage a little awkward if you leave the holder on the lens like i do; more expensive than standard filters- adapter, holder, lens cover, then you get to buy filters.this is a 'system' you're committing to. at the very least you need the holder, the correct size adapter ring for each lens size you intend to use, and some filters (which only work with cokin holders). the holder, adapter and lens cap will run about $25-$35 total, filters avg about $25.

Was worried about getting something online that was an actual and honest Cokin, but came in packaging and has the name brand on it. Is a quality product at a much cheaper price than I could have purchased directly from Cokin for. Have not purchased my filters yet but am confident using this product, if that changes will update my review.

I actually purchased the Cokin holder in order to compare it with one of the copycat holders. As far as the holder is concerned: The Cokin wins hands down. The copycat holders are dangerously tight. Mine are so tight that they actually scraped the coating off of the edge of my N8 filter. Not a problem with the Cokin holder. Filters slide in and out effortlessly, but are held snugly in place. Regardless of the brand of P series filters you have, the Cokin holder is a must. Highly recommended.

...and I'd like to dispel the idea that they are made of cheap plastic. 1. The adapters that fit the holders to the lense are metal with precision threads. They mate well with the lense threads and once they're put in place you should never have to screw another filter to that lense. They can be placed over a permanent protection or UV filter. For me, not having to 'screw' with filters is the number one reason for using the Cokin system. The #2 reason is not having to buy different sized filters and mess with ring adapters. Have you ever been on a windy, sandy beach shooting a sunset with a graduated ND filter and then wanted to change lenses? 2. The plastic is very hard, clean edged and flat where it is supposed to be. Mating surfaces and guides fit precisely The holder snaps tightly to the adapter; the covers snap into place and fit as tightly as your OEM lense cap; and the filters slide cleanly into position and stay in position. 3. They work particularly well where: a. you need to use more than 1 filter at a time b. for polarizing or star filters that require rotation c. for graduated NDs or split filters that require vertical or horizontal adjustment and rotation.They are much faster to change and adjust when working with fast changing light.The lense caps stay on. There is a gratifying, positive SNAP when they find their seated position and you know your expensive glass is well protected.Cons: There are a few downsides. For me they do not out weigh the benefits and I have adapted myself or made adjustments to the system.The adapters can get in the way of an on-board flash. I prefer to use a bounce flash anyway and rarely have a problem with barrel shadow - but the adapter easily slides off and on if need be.The cheaper AF lenses have front elements that turn with AF. You get used to turning the adapter by hand to adjust for the turning lense but it is a pain.The sides of the adapter cause vignetting with extreme wide angles - some lenses are worse than others and using a UV protection filter makes it worse. You could saw off the sides with a band saw but I've never needed to. Most of the time I am able to simply turn the adapter 90 degrees. Using 3:2 format the top and bottom of the frame do not vignette - at least to 16mm (my widest lense). And, again, the adapter is easily removed for that rare situation.The lense caps fit a little too tight. I once broke the handle off a lense cap trying to remove it. I now bevel the adapter and the lense cap where they lock together at 45 degree angles with a pocket knife. It also helps to develop a technique for levering the lense cap to bend it slightly, pushing inward near the center of the cap, while pulling the handle outward. Find a technique that works for you and practice it a little - it will quickly become second nature. In 30 years this is the only Cokin part that I've broken.In summary:I've been an advanced amateur photographer for 40+ years. I primarily use a star, gradual neutral gray, circular polarizing filter, and a +1/3 warming. 4 of my 6 lenses have Cokin adapters permanently attached. I find them to be a reasonable way to deal with a difficult problem. I hand hold the Cokin filters in front of the 300/600mm; and use the 50mm with extension tubes for macro work without filters because with close-up photography you can control the lighting.

I purchased these to use with graduated ND filters but find they just take up space in my bag now because I no longer use graduated filters I use Adobe Camera Raw Instead.I still give them a five star because they are a good product at a good price, and they may be useful to you.

Didn’t fit the filters really well, made a hell of a trouble to put them in and out - because of the cheap plastic it’s made of

New lens differrent diameter new filter holder. What more can I say? I knew I could count on Cokin!Thanks for having what I needed!

Portafiltri in plastica Cokin serie P. Buona fattura, rapido ed efficace il montaggio dei filtri, senza scivolamenti o giochi di alcun tipo. Utilizzato su Pentax K50, funziona bene senza vignettare fino al 17 mm. Il prodotto è di plastica ma di buona qualità. Molto leggero ma resistente. Il montaggio e lo smontaggio sulla lente sono facilissimi. Ottimo prodotto!

Si estás empezando con la larga exposición es la mejor opción. Mejor empezar por lo bajo y luego si se sube de nivel pues ya irás subiendo de calidad, que se nota, pero para empezar, no se pide más

I should have brought this first time round ... I brought a cheaper copy and should have brought this ..the polariser slot is perfect .. insert flat side towards you in the first slot nearest the ring adaptor .. the other 2 slots are then available to take the square filters.. you can then turn the polariser with the teeth rather than rotating the whole filter holder.

使い勝手がいいのか悪いのかよくわかりません。結局これを使わず、手でフィルターを持っています。
