Might not be what your seeking but just making you aware just in case it fits yuor purpose. I have a Canon 70-200 2.8 usm (Important it is a Non IS Version) 825. You can contact me on mail or I shall be keeping a close eye on activity.
Thanks was on the lookout for a mark 2. Since then I have tried one out and found them to be heavier than I thought. So going to go for a 24-70L instead.
