Changing the diopter lens
While holding the diopter lens base plate with both side panels of the finder, turn the diopter lens counterclockwise, and at the point where the white dot on the diopter lens aligns with the white dot on the base plate, remove the diopter lens. To mount another diopter lens, simply aligns its white dot with that of the base plate and turn clockwise. l In addition to the standard (-1.5) diopter lens, there are 5 others: +1, 0, -1, -2, and -3.
Detaching the finder
While pressing the finder latch (A), as viewed from the front, slide the nameplate to the right, and while slightly raising the front remove the finder.
Attaching the finder
Insert the two prongs on the back of the finder into the slots on the camera body, and while pressing the front portion of the finder toward the camera body, return the nameplate to its original position. The latch will pop out and the finder will lock automatically.
