I would like to know who uses screw in ND filters versus the slide in for the various holders. I am new and looking to get some filters and have been researching the various types,brands, and benefits of each. Obviously my first filter to get is a CPL, then perhaps a ND. I'd like to hear everyone's opinion. I do understand the possible benefits of the slide in filter, but as for money-wise goes, screw in are cheaper as you do not have to buy the adaptor. So, what do you guys/gals all think?
