Shooting big monkey is tough job! Especially when they keep moving around some twenty meters over your head. But with all the patience I can muster, I manage to finally get this Orang Utan's attention.
Full tripod shot together with my Manfrotto 190XB, fused with timer shot, all on an almost ideal condition. If you ask me, this may be the best quality I can squeeze out of this lens. Anything sharper, you have to upgrade to the Nikkor's $1300 AF VR Zoom 80-400mm F/4.5-5.6D ED! Or maybe, the Nikkor AF-S Nikkor 300mm F/4 IF-ED at $1000?
