The 90 AA in near mint or mint shape goes for $1600-2000, about twice the price of the previous E55 version or over 3x that of the large earlier E48 version. I've used all three and each produces great images that would be hard to pick out the differences in shots in a blind test of sample shots with the possible exception of those taken at f/2 or possibly f/2.8.
