The photo is with the anti-shake unit taken off.

BEFORE YOU TAKE THE ANTI-SHAKE OFF, be prepared to mark the numbers and locations of the shim washers. There are three positions for washers and each spot can have up to 2 washers. Mine had a total of 4 washers. The markings are the thickness in 1/100th mm and on reassembly, they should go back in the same place.

These washers set the flatness of the sensor to the front of the camera / lens.
