ND/GND filters please help
i've got a 5d, 17-40 and tamron 28-75, i bought the cokin z-pro holder and hitech filter sets (soft and hard). the z-pro holder is quite cheap, could be a bit better but does the job. i've been very pleased with the hitech filters i most often use in order: hard 0.6, hard 0.3, soft 0.6. i don't use hard 0.9 very often. i also have a 0.9 (non grad) which i use in combination with the above. added to that i also have a b&w 10 stop nd, which gets occasional use, but i'm half thinking of selling it. a 7 stop would probably be better for me.
