0


Nikon launched a lens compatible with APS-C July, 2011, the 40mm f/2.8 lens. This is a macro lens designed for cameras such as D7000 and D5100. A 60mm field view of 60mm is possible with this lens when mounted on one of the above mentioned cameras. It’s most notable features are listed below.

Technical Specifications:

  1. The 40mm focal length is conducive to focusing the images at a distance.
  2. The aperture value is between f/22 to f/2.8
  3. It works in DX format and 38°50? is the maximum angle of review at DX format.
  4. The total elements of the lens are 9 and total amount of lens groups are 7.
  5. This product has the ability to show the information about the object distance.
  6. The minimum distance of focus is 0.163m.
  7. The lens filter size is 52mm.
  8. Its dimensions are: (2.7×2.5 – D  x  L) and  (68.5×64.5mm – D  x   L) ;     L = Length, D = Distance (approx.)
  9. It weighs approximately 280 g.

Some other characteristics are shown below:

Lens Handling and Build:

The 40mm lens is made up of a plastic material body and a metal mount. A rubber made gasket has been mounted on the lens, for protection from dust particles.

Sharpness:

Its sharpness results are excellent. It is tack-sharp at f/2.8; but stops at f/4. At this point, this lens provides its sharpest performance. When the values decrease towards (f/5.6 or f/8), the sharpness remains constant, and no change occurs.

Chromatic Aberration:

If we analyze the overall performance, the chromatic aberration is low. It has been noted that fringing of the color is found in the areas of high contrast.

Shading or Vignetting:

The shading at the corners is notable at the point of f/2.8, the maximum opening point of this lens. Otherwise, there is not any point of corner shading that is mentionable.

Distortion:

In Nikon 40mm, distortion is well-controlled and practically negligible.

Autofocus Operation:

The Nikon 40mm takes some time to move upon its focusing range – it takes 1.5 seconds to focus on (close up to infinity). But if one makes small changes in the focusing, it will take less time to focus. The lens is equipped with a SWM, a silent wave motor, rendering it noiseless.

Given that this Nikon 40mm lens is priced for consumers, one would expect less expensive parts and the usual, associated issues with chromatic aberration, flaring and ghosting; however, distortion and flare issues are very minimal and the chromatic aberration is not serious. It’s a great lens for the price for casual photography and close-up shots.
