Cokin pros--cheap
readily available
easily stackable
fit on any lens with appropriate adapter
ND grads can move up and down
Cokin cons--resin
easily scratched
static attracts dust
bulky to store
NDs have magenta cast
Round pros--better quality
no colour cast
Round cons--Grads cannot be moved up/down to horizon
without step rings each filter will not fit all lens
The perfect photograph has never been captured but I will chase this elusive dream even if it takes me 1/60 sec.
