I have had 4 170-500mm dg and non dg and from my findings there was no difference in picture quality my findings were all the 170-500mmm I had were better and sharper than the 2 150-500mm os I had I now have a 50-500mm os and its awsome but i would still say the 170-500mm is as good at 500mm wide open and its a great lens beacuse its only 13kg so buy it and enjoy.
