I've seen some ND lenses on ebay which will fit my camera (55mm) but there are 3 different lenses, ND2, ND4 and ND8 what is the difference/significance.

I didn't know what the numbers meant either.

Had a search and found this...
>>>

(ND.3) (exposure adjustment = 1 stop)


(ND.6) (exposure adjustment = 2 stops)


(ND.9) (exposure adjustment = 3 stops)


(ND1.8) (exposure adjustment = 6 stops)


(ND3.0) (exposure adjustment = 10 stops)


(ND4.0) (exposure adjustment = 13 stops)


(ND6.0) (exposure adjustment = 20 stops)
