FAQs

What is the closest focusing distance for this lens?

The closest focusing distance for the Nikon AF-S DX Micro-Nikkor 40mm f/2.8G Lens is 0.15 meters (or 0.49 feet).

Can I use this lens on a Nikon FX (full-frame) camera?

Yes, you can mount this lens on an FX camera. However, it will operate in DX mode, cropping the image to the smaller sensor size. The effective focal length will be approximately 60mm.

What is the difference between M/A and M focus modes?

M/A (Manual/Auto) mode allows you to autofocus and then instantly switch to manual focus by turning the focus ring. M (Manual) mode disables autofocus, allowing only manual focusing.

How do I achieve a blurry background (bokeh) with this lens?

To achieve a blurry background, use a wide aperture (like f/2.8), get closer to your subject, and ensure there is significant distance between your subject and the background. Using a longer focal length can also enhance bokeh.

What is included in the package?

The package typically includes the Nikon AF-S DX Micro-Nikkor 40mm f/2.8G lens, a lens cap (LC-52), a lens pouch (CL-0915), and a sun shade (HB-61).

Is this lens good for portraits?

Yes, the 40mm focal length on DX format provides a natural perspective similar to a 60mm lens on FX, which is often considered flattering for portraits. The f/2.8 aperture also allows for good subject isolation with a pleasing bokeh.

Troubleshooting

Autofocus is slow or hunts

Ensure the focus mode switch is set correctly (M/A or M). Check if the subject is too close for autofocus to lock on; switch to manual focus if necessary. Ensure the camera body and lens contacts are clean.

Blurry images in macro shots

Macro photography often requires a tripod and careful focusing. Ensure you are within the lens's operational focus range. Use manual focus and magnification in live view for precise focusing. A shallow depth of field at f/2.8 means only a very thin plane will be in focus.

Lens does not communicate with camera

Check that the lens is securely mounted to the camera body. Clean the electrical contacts on both the lens and the camera mount with a dry, lint-free cloth. Try resetting the camera settings.

Pros and Cons

Pros

  • Excellent for detailed close-up and macro photography.
  • Versatile focal length suitable for portraits and general use.
  • Fast f/2.8 aperture performs well in low light.
  • Quiet and accurate autofocus with SWM.
  • Allows for creative shallow depth of field effects.

Cons

  • Requires specific techniques for optimal macro results.
  • May exhibit chromatic aberration at wide apertures.
  • DX format limitation restricts use on FX bodies without cropping.

Setup, Compatibility & Care

Compatibility: This lens is designed for Nikon F-mount DSLR cameras with a DX (APS-C) sensor. It will mount and function on FX (full-frame) Nikon DSLRs, but the image will be cropped to the DX format. Ensure your camera body is compatible with AF-S lenses for full autofocus functionality.

Attaching the Lens: Align the white mounting index on the lens with the corresponding index on the camera body and rotate the lens clockwise until it clicks into place.

Focus Modes: The lens features two focus modes: M/A (Manual/Auto) and M (Manual). The M/A mode allows you to override autofocus by simply turning the focus ring, while M mode locks out autofocus entirely. Select the desired mode using the switch on the lens barrel.

Care:

  • Cleaning: Use a soft, lint-free microfiber cloth to gently wipe the lens elements. For stubborn smudges, use a lens cleaning solution sparingly on the cloth, never directly on the lens. Blow dust off with a lens blower before wiping.
  • Storage: When not in use, attach the lens cap and store the lens in its protective pouch in a dry, dust-free environment. Avoid extreme temperatures and humidity.
  • Sun Shade: Attach the provided HB-61 sun shade to prevent lens flare from direct light sources and offer some physical protection to the front element.
