This 105mm f/2.8 lens is the sharpest in my arsenal. I took an absolutely amazing closeup of water droplets with my N8008s on a strand of wild grass where the droplets acted like a convex lens. You could actually see the inverted image in the small droplets.I've now made the transition to a D70 and the lens works great there too. With the 1.5X magnification for the APS size sensor, it extends the working distance and gives greater than 1:1 magnification. The images still look great at 6.1 megapixels.Highly recommended!
