Nikon VAF Installation & Removal

Recovered handling instructions for the discontinued VAF-D600 and VAF-D800 removable optical anti-aliasing filters.

BEFORE YOU BEGIN

Read the Complete Procedure First

The D600 and D800 filters used the same general installation and removal method. The photographs below preserve the original procedure.

Historical documentation only. These products are discontinued. This guide preserves the original operating procedure and does not represent current product availability, compatibility, service, or installation support.

HANDLING & OPTICAL CARE

Protect the Filter and Camera Interior

01

Handle by the Edges

Remove the filter from its container and protective wrapping while holding only its corners and edges.

Remove loose dust with a suitable clean-air optical duster.

02

Use the Supplied Tool

The original kit included pointed tweezers for installation and removal, plus a lint-free optical cloth for cleaning and storage.

03

Clean Gently

Fingerprints were removed with a small amount of alcohol-based lens cleaner on soft optical cloth.

Avoid vigorous rubbing or dragging abrasive particles across the coated surfaces.

INSTALLATION PROCEDURE

Installing the VAF-D600 or VAF-D800

The photographs below preserve the original D600 procedure. The D800 filter followed the same general installation method.

Always hold the camera vertically during installation or removal. This reduces the possibility of a dropped filter or tool falling toward the image sensor. Never force the filter into position.
01

Inspect the Filter and Tools

Unwrap the filter while holding it by its edges.

Confirm that the pointed tweezers and lint-free cloth are available, and remove any visible loose dust before approaching the camera.

02

Select Mirror-Up Mode

Set the camera's release-mode dial to Mup.

This allows the reflex mirror to be raised without opening the focal-plane shutter, helping protect the image sensor during installation.

03

Identify the Five Engagement Points

Remove the lens and press the shutter-release button.

With the mirror raised, locate the five shallow rectangular depressions along the front edge beneath the reflex mirror. The filter's five upper tabs engage these points.

Mirror-up interval: The recovered instructions state that the mirror remains raised for approximately 30 seconds and then lowers automatically.

04

Grip the Filter From the Flat Front Side

Insert the tweezer tips into the two holes at the bottom of the filter.

Approach from the front, flat side, not the rear beveled side.

Confirm that the five small protrusions are at the top.

05

Hold the Camera Vertically

Orient the camera so its lens opening is vertical.

Maintain this position throughout installation so a dropped object cannot fall directly toward the image sensor.

06

Engage the Top of the Filter

Press the shutter-release button to begin a new mirror-up interval.

Angle the filter into the camera and guide its five upper protrusions into the corresponding depressions beneath the reflex mirror.

07

Seat the Lower Edge

Gently press the bottom of the filter into the camera so it engages the groove at the base of the mirror cavity.

Correct installation requires very little force.

If it does not seat easily, stop. Do not force the filter.

If the mirror-up interval ends, gently withdraw the filter and allow the mirror to return normally before trying again.

08

Confirm the Filter Is Flat

When correctly installed, the filter's flat front face sits within the camera body parallel to the lens flange.

09

Verify the Lower-Edge Engagement

Inspect the lower edge carefully.

On the original design, it must be fully engaged in the base groove behind the crescent-shaped cutout.

If necessary, apply only gentle pressure to seat it fully before mounting a lens.

LATER HOUSING REVISION

Filters Shipped After Approximately April 2014

Later VAF-D600 and VAF-D800 filters used a revised mechanical housing.

A crescent-shaped protrusion extended from the bottom of the filter into the corresponding lens-flange cavity.

This version did not snap into place like the earlier design. Two small rubber pads retained it by gentle friction.

Important: Existing owners should identify which housing design they have before interpreting the lower-edge seating instructions above.

REMOVAL PROCEDURE

Removing and Storing the Filter

Removal reverses the installation sequence and uses the same supplied pointed tweezers.

Keep the camera vertical during removal. Hold the filter securely by its handling holes and use only gentle force.
R1

Raise the Mirror and Lift the Filter

Remove the lens, select Mup, and raise the reflex mirror.

Insert the pointed tweezers into the filter's handling holes, gently lift the lower edge from its retaining groove, disengage the upper tabs, and withdraw the filter from the camera.

If the mirror begins to lower, gently continue withdrawing the filter and allow the mirror to return normally.

R2

Wrap and Store the Filter

Inspect the optical surfaces without touching them.

Wrap the filter in the supplied lint-free optical cloth and return it to its protective container to keep it free from dust and contamination.

FINAL CHECK

Before Returning the Camera to Use

  • Correct VAF-D600 or VAF-D800 filter is matched to the camera
  • Five upper engagement points are correctly seated
  • Lower edge is correctly retained for the applicable housing design
  • Filter face is flat and parallel to the lens flange
  • No dust, tools, or loose material remain inside the camera
  • Optical surfaces remain clean and free of fingerprints
