Never Say Never with Sigma APO 150-500mm F5-6.3 DG OS HSM

If you don't try, you will never know. And that's what I did today during lunch - try out this monster lens from Sigma. You be the judge, one shot at 150mm and another at 500mm. When you use non-Nikkor lens, you basically loose the 3D Matrix Metering II edge of the Nikon D90. Both handheld with OS set to mode II (active).
