85L II, sold because of lack of use, but the lens is so unique and the images can be so striking -- I want to put more effort into it again.
300 f/4 IS, even though I have the f2.8, I'd like to have the f/4 again for times when portability is an issue.
24-70 II, returned mine but will purchase again when the price better corresponds to the performance of the lens.
