Hi guys,

This might be a stupid question, but I'm looking to get some cheap grad nd's for my Tokina 11-16 for sunset and sunrise landscape shots, and I'm going to order the Lee 4x4 Filter Holder and the 77mm Wide Angle Adapter Ring, but I'm wondering if it's possible to buy cheap eBay filters rather than spend hundreds of dollars on the genuine Lee filters while I'm learning how to use them. Do all filters 100mm fit in the Lee holder or only Lee filters? I plan on buying the genuine thing but as I'm just starting out I want to learn how to use filters properly before investing so much money into them.
