Cokin P filters on LF?

[fschifano]

I use the Cokin P filters, and even the Cokin P series polarizer on large format with a 150 mm lens, on 6x6 with a 50 mm. lens, and even on 135 with a lens as short as 24 mm. No problems with vignetting.

I've used P series filters on 90mm for 4x5 no problem with vignetting.

Please note that I use the Lee system but whether or not you get vignetting will depend on more than just the filter size and focal length of the lens. For example you might find that for LF which is typically used with small apertures you don't get vignetting but on a fast MF lens fully open you do. Obviously the number of filters/slots and whether or not there's a round polariser attached to the front also has an impact.

If you really want to be sure I'd suggest you get a piece (or more) of cardboard and cut a hole which is the final size of the filters you anticipate you'll use. Stack enough cardboard so that it's the same width as your filters will be. Attach this to the front of your lens with some rubber bands, open up the back (or take off the ground glass), set the aperture to what you anticipate you'll use, trip the shutter on a bulb setting and look through the corners from the back of the camera to see if you can see the edge of the filters. If it's clear you won't get vignetting but if it's obscured you'll either need to use a smaller aperture or a larger filter size (or use it for artistic appeal like a Holga).

I use Cokin P filters on my LF.

I don't use a lot of filtration - some yellow or yellow-green, sometimes a grad filter, either gray or something to increase sky contrast. Cokin is reasonably priced, and a set of filters is compact enough and light enough to not be a burden to schlep around in the bag. No problem with vignetting on my 210; I had some experience using them on my 90mm f8, but not enough to make a generic 'no problem' comment.

I use a Cokin P holder and hood sections on lenses up to 77mm (my 90mm wideangle on 5x4). In fact I use it as a cheap substitute to a compendium hood most of the time. I do have a P polarizer (it is round, and rotates in the holder) though I don't use it much. I mostly use yellow/green or green screw filters for landscapes.

I rarely need to burn in skies except for effect. I get a decent tone for blue sky without filtering. I used to get blank white skies when I underexposed/over developed my film. I was young and foolish then!

I use the Cokin P holder for my HiTech filters without any vignetting on my 135mm, 210mm and 400mm lenses. For my non-square filters (ie: polarizers) I just use screw-in filters. I find the convenience of having the Cokin P holder really nice and haven't had any problems with it.
