    2x cut down 1 stop
    4x cut down 2 stops
    8x cut down 3 stops

    depend how many stops you want to cut down (the most), and get the filter you want.

    thanks. the stop part is where i'm confused. 2x means half the amount of light entering, and hence prolonging the shutter speed by 2 times (e.g. 8 secs to 16 secs)?

    You can stack the filters, but must check if the stacking cause vignette or not lah.Different lens will have different tolerance in filter stacking

    yes,

    8 sec to 16 sec is 2 times = 1 stop
    8 sec to 32 sec is 4 times = 2 stops
