Just wondering if you really need a white balance expodisc for each lens...or can you get away with one for your largest lens and then use it for all of the smaller ones by just holding it in place?
Any info is appreciated. I would like to order one in in the next day or two but I need to know how many I should order.
Just one for your largest lens. Holding it in place works just as well on all my smaller lenses, so don't let anyone tell you differently. I use the WB and the warming disc, and I get great results with my 77mm disc on all my lenses.
