Summary: I purchased the lens for street photography in conjunction with my D700 and F100. I wanted manual focus as most pictures would be taken without looking through the viewfinder but rather guessing the frame and trying to remain inconspicuous. The lens works extremely well with excellent sharpness and color rendition. When I print in monochrome I get excellent gradation across the image. Overall it has become my most used lens.
Summary: Nikon's so-called 'pancake' lens. Very small, extremely sharp. Not fancy, just takes great pictures and takes up virtually no space, making it more likely you'll have your camera with you when you need it. Forget those low-res pictures from pocket digital cameras and try a photographer's gear.
