Filter Use

Cory Waltz · Mar 29, 2004

I've been toying with the idea of getting a Cokin P filter holder, and a couple of HiTech GNDs. For those of you who've used the Cokin system, how did you incorporate a circular polarizer? Did you use the Cokin one, or did you just use a round circular polarizer and then attach the Cokin holder? If the latter, is getting the circular polarizer set correctly a problem?

Thanks for the help.

I thought at least 1 person would have responded by now. Maybe I should have said something about incorrect focus in the title... or that the 10D is discontinued.

She uses Cokins.

Thanks Juli. If she doesn't chime in I'll send her an email.

Now I can't remember what the question was LOL--OH--yes, I use Cokin P. I actually do use the Cokin circular polarizer. I also recently purchased the blue/gold polarizer also for different reasons. I believe there might be another circular polarizer--perhaps Singh Ray (which is MUCH more expensive) but the Cokin one does a good job.

I'm not sure what you are asking--do you mean use a circular polarizer and then try to fit the Cokin on top of that? I'm not sure if you know how it attaches, so here is a link so you can see it
http://www.geocities.com/cokinfiltersystem/howitworks.htm

You must attach the lens adaptor ring to your lens/protective filter and then the holder slides down over that. The filters slide into the slots in the holder. If you look closely, you will see that there is a thin slot very close to the lens--this is where the polarizer fits--and then it turns within this slot--or you can turn the whole holder--just as a regular circular polarizer works. No difference.

The reason I use Cokin is because I have 9 lenses and am able to use a filter (I have NDs and ND grads, polarizers, IR filter [actually gel that fits in a gel holder and fits in filter holder altho' there is now an 89B filter that works instead of having to buy a gel] with all my lenses simply by having an inexpensive adaptor ring for each lens. When I was shooting with an Oly E10, Jaja (a 'used to be' contributor to this forum--but who has quite an interesting sie of his own in Belgium http://www.belgiumdigital.com/ ) got me interested in the Cokin setup and I've been using it for a number of years--simply adding lens adaptor rings as I've bought and sold lenses and cameras.

Hope this helps.

I only use a UV filter to cut glare... And to protect the main lens.

I do not use any other specialty filters anymore as I can reproduce anything I want in Photoshop. More flexibility that way with the original image.

I'm a long time PS user and am pretty good--you can't reproduce the results from a polarizer very easily--you can layer mask/ correct, but if you don't get some clouds and some 'interesting' sky to begin with, you can't bring that up in PS. You can replace the sky, 'recreate' the sky--but a polarizer helps with both sky---and OF COURSE--it eliminates 'glare' from metal, water, etc. You also can't reproduce REAL IR----and you can't 'soften/silken' water without using an ND filter in the case of not being able to drop the shutter speed sufficiently.

I agree with your points on not being able to reproduce the polarizer and see the benefits to using the ND, but from what I know of the Cokin system the filters are plastic right? How does that compare quality wise (optically) to a $100+ glass circular filter? Would it affect the image quality much?
