What do you all think?

Is it worth the money for an expodisc? Would this perform better than a grey card?

Yes, I'd take an expodisc over a gray card, more flexible.

Thanks for your reply... but I don't know what you mean by "more flexible"

I'm sure they work great, but would it perform better than a grey card? I was gonna pick one up because they're smaller and look cooler! lol Until I saw the price tag. lol

Besides, the expodisc is 3 or 4, times more expensive! I can use the money for a polarized filter instead?

Thanks man!

just go to the paint section at home depot and get a paint chip card in the grey that is the same colour as the grey card...or even pick up a few different shades to experiment with...FREE!!!!!!1
