I am planning on buying this lens and was wondering if I used a Cir-Pl on the hood front lens will it cause vignetting? did anyone try it? What about using Cokin?
you cannot put any filters in fron of the lens.
It has a place to cut out and put filter gel on the back of the lens (I think)
I don't think you can put a cpl on it since it has to be rotated.
