Re: IS blurring : does your 24-105mm f4 L have this problem?

Hi,

I like this thorough explanation below of exactly what decentering on a lens is from LensRentals if your interested. Very clear and concise.

Especially the idea of using notebook white reinforcing tabs on a black background!

I think I will try this when I get my lens back from Canon.
