I have two Cokin-brand P-size (84/85mm) slide-in filter systems to give to the first 2 Veterans of US armed service who ask. For more info, see http://www.cokin.co.uk/
After looking at Cokin's what-size-filter-system-do-I-need chart, I believe the lens-length-v.-filter-size line between the P and the Z system is 28mm (35-e). That is, these filters will not vignette the image thru a 28mm lens, while they will vignette an image seen thru a lens shorter than 28mm. (I recently bought a Hitech 100mm system...see https://photography-on-the.net …/showthread.php?t=1296538
...for my 17-40 and 24-105 lenses (used on a 6D, FF body).

EACH system includes identical sets of:
1. Filter holder.
2. 58mm and 77mm adapter-rings.
3. Filter-holder slide-in cap. This protects the slide-in filters from being damaged from the front.
4. Two slide-on adapter-ring caps. This allows you to remove the filterholder and still protect the front of your lens without having to go to the trouble of unscrewing the adapter-ring from the lens. When I was actively using this system, I had a ring (with slide-on cap) on every lens I carried.
5. Snap-on sunshade.
6. A #164 circular-polarizer filter. This is a round filter that slides into the holder in the rear-most position and that can be rotated independently of the holder*. Both circ-pols are useable but NOT in great condition.
I then have 2 more adapter rings, one 58mm and one 67mm. Pls let me know which of these 2 you want and if you do NOT want either of the 58mm or 77mm adapter rings.
* ...which perhaps has been rotated to a particular point to get the line of a grad-ND filter in the correct position.
