I have the above lens, which is sharp as a tack with great rendering on my 5D.Has just a bit of oil on the blades and affects being able to stop down to f22 with out a lot of help.Goes to f8 no problem.Is it worth opening up to clean them or should i let it go? How difficult to get to the blades.Also the focus ring is stiff.Anything i can do to loosen this up? Any help is always appreciated
