A collectible for your collectibles

It's taken you the better part of your life so far to assemble that collection of cobalt-blue antique glass bottles. Now's the time to document them with a lens that's made to feature every detail of your collection. The wide, 7-bladed aperture will isolate the focus squarely on the details you'd like and knock the background to a pleasing, feathery blur.

This lens is perfect for taking rich, high-resolution images of food, flowers, insects, and textures; but dial the focus towards more distant objects and more pleasant surprises are in store. This lens has the ideal focal length for general portrait and landscape photography as well. The ultra-quiet, fast auto-focus will make sure your pictures are tack-sharp. Plus, you'll find this lens's versatility brings presence and dimension to your video as well.

Warranty Information


Overview: The Nikon AF-S DX Micro Nikkor 40mm f/2.8G lens is a fixed focal length lens with a natural wide angle view, and a f/2.8 aperture. It is ideal for general close-ups, delicate flowers, detailed collectibles, copy photography, portraits, and landscapes.

Super Integrated Coating: Nikon's Super Integrated Coating enhances light transmission efficiency and offers superior color consistency and reduced lens flare.

Silent Wave Motor (SWM): The exclusive Nikon Silent Wave Motor (SWM) enables fast, accurate, and quiet auto focus.   

Focus Mode Switch: The Focus Mode switch on the barrel of the lens lets you easily switch between manual focus and auto focus. If you want to enable auto focusing, the camera must be set to Auto Focus, and the switch on the lens needs to be set to "M/A". With most Nikon D-SLRs, the lens gives you a manual override option, allowing you to rotate the separate focus ring while pressing the shutter release halfway.

Focus Limit Switch: In addition to the Focus Mode Switch, the lens has a 2-way Focus Limit Switch, which determines the focus distance limits for autofocus. You can select "Full" for subjects that may be closer than 0.7' (8.4"), or Infinity-0.2m if the subject will always be at the distance of at least 0.7'.

Diaphragm: The lens is equipped with a rounded 7-blade diaphragm.

Lens Hood: The lens comes with the HB-61 bayonet-type lens hood. The hood adds approximately 1-3/4" to the overall length of the lens. You can invert the hood and snap it onto the lens for storage, if desired.


  • Type of Lens: Type G AF-S DX Micro Nikkor lens with a built-in CPU
  • Type of Mount: Nikon F-bayonet type
  • Filter Diameter: 52mm
  • Focal Length: 40mm
  • Closest Focus Distance: 6.4" (0.53')
  • Focusing Method: AutoFocus using a Silent Wave Motor, manually by a separate focus ring
  • Aperture Range: f/2.8 to f/22
  • Lens Construction: 9 elements in 7 groups

Great lens

Written By Nitro, Catskill Mts NY on Sunday, March 16, 2014

Crutchfield Customer Review (What's this?)

Superior lens for the price

Pros: Quality

Cons: None

A great duel purpose lens

Crutchfield Customer Review (What's this?)

I had a 35mm Nikkor, and after doing some reading, the option of having almost the same lens was too much to resist. I wanted a micro lens and with the minute difference in focal lengths, I sold my 35mm and purchased the 40mm. Although I lost a stop or two, it still serves as a great walk around and portrait lens.

Pros: Affordable introduction into the world of micro. Lightweight but built very sturdy. Serves as a sharp everyday "walk around" lens. It's a Nikon.

Cons: Not good for getting close to living objects as butterflies or such.

Still new to me

Crutchfield Customer Review (What's this?)

I just learning how to use this lens. I compared it my 18 - 50 mm that came with my D3200 and the clarity was greater. I'm just not sure it was $280 better but as I stated I'm just learning how to use it.

Nice lens

Written By Gturns, Miami, Fl. on Thursday, August 08, 2013

Crutchfield Customer Review (What's this?)

Really nice close up lens for the price.

Pros: Clear, perfect auto focus.

Cons: 40mm is a bit short. You do have a 1:1 lens, but have to get really close, so close that you lose your light getting the 1:1 ratio. I believe that for the price this is a nice lens. BUT the 80mm is a lot nicer... the price is higher as well.

Great Little Lens

Written By JR, Memphis, TN on Thursday, March 22, 2012

Crutchfield Customer Review (What's this?)

The 40mm F2.8 macro is a good little all around lens. It is sharp wide open and sharpest around F5.6 center to edge. The angle of view is slightly more than a normal lens. It is good for close ups and general photography. Bokeh is good. The lens is small and compact and uses a 52mm filter. I bought this lens to use with D5100 and the combination is perfect for me.

Pros: Sharp Compact F2.8

Cons: None
