    I would like to buy a few natural density graduated filters. Lee or the Singh-Ray ones... I am not sure which size I should buy. I would like to use them with my Canon 17-40mm f/4 lens (filter size 77mm) or I can borrow my friends Nikon 14-24mm 2.8g lens.
    Which filter size should I buy? The 4x6 is twice as much...
    Thanks!

    P size filters are 85mm wide (could be 84, it doesn't matter much). You can absolutely use a p size filter on an 82mm lens (I do). Whether that causes problems with vignetting or whatnot is another concern: mine is an 8x10 lens with a fair amount of movement available.

    77mm is perfectly usable with P size.

    Or you could go with the lee holder (4in x 4in) which can be used with the 4x6in filters. If you think you might need to go bigger. I chose P size because it is as large as I currently need and it is much cheaper all the way around. I have a number of filters, and it really makes a difference.

    There are no ways to attach filters of any kind (except for Lee's special type) to Nikon 14-24G lens. The lens comes with built-in/non-removable hood with deep cut-outs and no threaded filter ring. I know Lee has a specially made (and very expensive) bracket for this lens either announced or available.

    With my 24-70 Nikon f/2.8, standard P style bracket causes vignetting below 28mm or so. I know Cokin makes wide lens bracket (has only one slot for filter so it's thinner) but I do not have one. You are probably pushing it too far with 17mm....
