Excerpt: There was a need in the camera bag for a prime lens faster than the usual zooms and this fit the bill perfectly. Used it while at the ABQ Dragway shooting the jet cars for the team, both action and candid. The f/2.8 rating coupled with ISO made for some great shots when time was critical. Nice and light and fast focusing with outstanding optics make this one a keeper.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Rugged
Summary: The lens was a birthday gift for my daughter. She uses it all of the time for macro photography. She says that it is an awesome lens. I have a 50mm Nikon 1.4 and I love this prime lens. You cannot go wrong with Nikon lenses.
Excerpt: This is the first lens I have bought in a long time. I use this lens mostly for close-up macro photography. With the fast f 2.8 lens you can get really close up and get great macro photos. The auto focus works really well even you're very very close to your subject. The lens also works well for portrait photography.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I've mostly used the 40mm as a normal lens and found it to have great edge-to-edge sharpness. I would still give the 50mm f/1.4 the edge in overall 'look and feel' of image quality, but the 40mm is sharp
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus
