    Prices vary quite a bit now.. All the GNDs have increased in price to around 40. Cir-Pol for P holder is $70 I think.

    3 slot means you can slot in 3 filters. 1 slot means you can only slot in 1 filter. 1-slot holder is thinner, so it will vignette less for wide angle lenses. If using UWA on APS-C cameras, you must use the 1-slot wide angle holder. For canon is less problem since crop factor is 1.6. For 1.5x crop factor, some 10mm or 11mm lenses will cause vignetting issues even when used with the 1-slot wide angle holder.

    BTW you are using FF camera with UWA lens. Cokin P series (84mm wide) will not be wide enough for you. You will definitely see vignetting. You will need to go for 100mm (4 inch) filters. So either Cokin Z-pro series, Hitech 100mm filters/holder or Lee foundation kit/filters. And sorry to tell you, the prices for those are quite a bit more expensive.

    For all three Lee, Hitech and Cokin, the holders are sold separately from the rings.

    Lee foundation kit (only the holder. expansion to 3 slots is included) cost around 120+. The adapter 77mm ring cost 70+ to 90+ depending where you buy it. Hitech holder cost around the same also, and the ring cost 60+.

    Why Hitech filters are cheaper? DOn't know. You might want to give them a call or drop them an email. Actually Hitech is made by Format filters. Format Filters are high end and very expensive glass filters. Hitech is their cheaper range of resin filters.

    Lee offers both glass and resin filters. But they are more expensive.

    Cokin also offers 100mm resin filters. But many people have reflected that Cokin filters gives color cast. I find it true for their P series filters, but never had any experience with their Z-pro filters.

    Schneider (makers of B+W filters) also makes 100m slot in filters. Their filters are all glass I think, and are so expensive that I peed my pants when I first saw their pricing...

    is Lee foundation kit holder only have 3 slots, cokin has 1 and 3 slots, 1 slot good for wide angle.
    i am using for wide angle on my full frame 5Dmk2, will the Lee foundation 3 slots holders cause vignetting?

    so i should buy Lee holder($120) + Lee adapter ring(about $70 to $90) + hitech GND filters

    or Hitech holder($120) + Hitech ring ($60) + hitech GND filters

    or Lee holders($120) + Hitech ring ($60) + hitech GND filters?

    Are you using hitech GND filters too, which holders and adapter ring are you using?

    No. It will be fine.

    so i should buy Lee holder($120) + Lee adapter ring(about $70 to $90) + hitech GND filters

    or Hitech holder($120) + Hitech ring ($60) + hitech GND filters

    or Lee holders($120) + Hitech ring ($60) + hitech GND filters?

    Are you using hitech GND filters too, which holders and adapter ring are you using?
    Lee holder can only use Lee adapter ring. Hitech holder can only use Hitech adapter ring.

    Filters don't matter. As long as they are 100mm wide. they will fit. I am using Lee holder and 77mm lee adapter ring and hitech GNDs. No particular reason, because I got them 2nd hand at a very good price.
