Of course you do. You do know there's a simple acid test for determining whether or not you need a particular piece of gear, right?Man, I'm looking at ND filters as we speak! Watched a couple videos and I think I HAVE to have one or two!!
Now slow down there!! I'm just a babe-in-the-woods here! I heard one guy say go fixed, because you'll be constantly having to remove the ND for adjustments and all. But can't you just dial down a variable to zero for your other adjustments, then dial it back up, without having to remove it? Of course, I see the variable's are a good bit more expensive too! What are the costs for fixed ND "holders"? Thanks!
