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.
Summary: A wonderful lens designed with foresight and understanding of the needs of photgraphers not found frequently these days. Designed for manual focus but with data connection to digital bodies it is a robust, smooth, tiny lens which is sure to become a future classic.
Summary: Based on so many reviews praising this lens for its ability to render smooth out-of-focus elements (boke or "bokeh"), I picked one up with high hopes. Sadly, I was pretty disappointed when trying to shoot flowers and finding the background harsh and distracting, even moreso than my 50mm f/1.8D.
Summary: The 45mm f2.8P is one of the best primes you can get for the Nikon mount. That said, the lens design is old (cheap) but yet Nikon expects you to pay more for this lens than the 50mm f1.8D? The bokeh on the 45mm is great ... but you can argue that the bokeh on the 50mm f1.8D is just as good ... and the 50mm f1.8D is MUCH cheaper. Sure, it's manual focus unlike the 50mm F1.8D which has autofocus ...
