I am looking to buy both a CPL and ND filter.
I currently have 70-200mm F4 and 17-55 2.8 (67mm and 77mm filters)
As far as I am aware, there are two options:
- A filter for a thread size
- A "kit" which holds the filter and you can basically use it on any filter size - provided you have the largest filter size to start with
How do you even go about choosing which route to go down? My friend using the holder/steppers for his ND filter kit and it seems like a bit of a hassle. I really don't know anything about this besides that I use a decent UV filter on my lens at all times 
Thanks for any help...
