Both Singh-ray, Tiffen, and Hitech (forgot that one yesterday) make Cokin P -size filters (84 or 85mm). Lee's standard size is 100mm. Can't remember if they will deliver P size on demand. BTW, BH has a rather comprehensive webpage on rectangular filters, where you can compare prices of different makes for a given type of filter.

Re: Rectangular filter systems
- Original Message - From: W.Xato [EMAIL PROTECTED] But does the polarizer have a color cast when using it? The Cokin ones in the store look green to me. My Cokin ND grads were also green. I discovered a colour skew looking at some pictures of a forest interior, and compared the colours with and without the pola. My first thought was blue-gray, but maybe I should look again. Anyway, whether it's blue-gray or green, it's not how it should be... Best, Jostein
Re[2]: Rectangular filter systems
Hi, The hitech ones are much better and are generally regarded as the best value/quality buy. I have an unused Hitech filter holder with 2 filter slots, a circular holder for polarisers and a 77mm attachment thing. Also an unused Hitech graduated neutral gray filter. If anybody's interested in buying them I'll listen to any reasonable offer, to include shipping from the UK. Replies in private, please. I've also got one with 3 filter slots and I'm pretty certain I have a 2nd grad. ND (different strength), but I can't find them at the moment. I can't tell what strength the grad. nd I can find is - it's not written on the packaging. --- Bob mailto:[EMAIL PROTECTED] Thursday, September 5, 2002, 3:11:28 PM, you wrote: I have heard many times that the cokin filters are far from neutral in colour even from day 1.

You can get some combo packs of lee grads stuff which look quite interesting and I think I can afford it. Cokin X-Pro is just ridiculously expensive.

I was looking to get a filter holder and a couple of filters for the 55mm 67 lens. I almost fainted at the price of the X-Pro stuff. Needless to say I didn't buy anything. If I had have done, I wouldn't have been able to afford to go on holiday so negating the use for the filters anyway!

O Pentaxians -- Do any of you use these? Lately I've been feeling the need for an ND grad, which sort of precludes the screw-on approach. The Cokin P system, at 84mm, seems big enough for most Pentax lenses except the really big glass and one of the 6x7 lenses that has a 100mm filter diameter. Singh-Ray seems to favor this size as well. I'd be happy to hear comments, praise, damns-with-faint-praise, caveats, yike-don't-do-thats, etc. from the assembled wisdom. Best regards, Stephen Moore

Singh-Ray seems to favor this size as well. if you use a ND gradient filter of any type, you cannot use a direct screw-on filter except in the most limited of circumstances. you have to go to a separate filter system with moveable filters. Cokin filters are prone to fading or color shifting, so be prepared to replace them periodically. other vendors should be more fade resistant. Herb
Re: Rectangular filter systems
the only complaint is that i can't attach lens hood so there is more likely to have flare. - Original Message - From: Stephen Moore [EMAIL PROTECTED] To: Pentax List [EMAIL PROTECTED] Sent: Wednesday, September 04, 2002 12:11 PM Subject: Rectangular filter systems O Pentaxians -- Do any of you use these?

Re: Rectangular filter systems
Hi, Steven. First, it is a hazard to use Cokin P on lenses with 77mm filter diameter. The reason is simple. If you measure the diameter on inside of the Cokin P holder, it's 75mm. I know it is proclaimed to work with some lenses of larger diameters, but don't count on it. It produce detectable vignetting with lenses like 645A*300/4, 645A45/2.8, FA*400/5.6 and to some extent on FA*24/2 and FA20/2.8. I know, why put a filter on a 400, but a gradual gray comes in handy sometimes anyway. Its is true as has been said about the cokins that they can change colour over time. My gradual gray (G2) give a slight green cast, and recently I discovered my pola to give a blue-greyish tint. They're both in line for the thrashcan as soon as I can have them replaced. The big advantage of Cokins is availability and price. Btw, Cokin also produce a filter series larger than the P. But more pricey of course. You mentioned Singh-Ray; other brands are Lee and Tiffen. http://www.leefilters.com/ http://www.tiffen.com/ Best, Jostein - Original Message - From: Stephen Moore [EMAIL PROTECTED] To: Pentax List [EMAIL PROTECTED] Sent: Wednesday, September 04, 2002 9:11 PM Subject: Rectangular filter systems O Pentaxians -- Do any of you use these?

I believe that the graduated gray filters work based on what I've seen in several different publications. The before and after pictures convinced me. I bought the Cokin P ones because they're cheap and I wanted to make sure they made a difference before I went for the expensive glass ones. I used them last weekend and I haven't gotten my pictures back yet so I can't tell you how I did. I can tell you that it's difficult to see the line between light and dark when you look through the viewfinder. You have to stop down pretty far for the filter to work effectively and the viewfinder gets dark enough that it's hard to see the difference that the filter makes. The articles mention that turning the filter makes it easier to see. I'll keep practicing...
