Filters on Fuji 14mm lens
Just get step up rings and keep your filters all one large size. You just change step up ring to suit what ever the diameter of the lens is at the time. My filters at massive 77mm - from my days using the Tokina 12-24mm on my Fuji S3 Pro. But I can use the same filters on every lens I have cause I have the step up rings.
Might be a funny look but works great and certainly no vignetting at all.
