What size Cokin filter holder?

[tom beard]

I'm about to order a Cokin "P" series filter holder and filters. The P series is big enough to accommodate up to 28mm wide angle of view on a standard 35mm format ( I'm assuming an FX sensor). I have an 18mm/105mm DX zoom lens and a crop frame body (Nik D-90). The APS equivalent on the wide end of that lens is 27mm. Since I will be shooting wide angle landscapes, should the P series size be OK , or should I get the larger holder size to avoid vignetting? Thanks, Tom Beard

You should be fine with the 'P' Series. I used them all the time with my 18-70 on my D300 with no issues, in fact, you can almost get away with an 'A', but I wouldn't recommend it.
