Phase One 645 AF manual Setting diopter, Adjusting the Strap

2.10 Setting diopter

Look through the viewfinder and make sure that the focus frame (Rectangle with Circle) is in sharp focus. If it is not, turn the diopter adjustment dial in the “–” direction if you are nearsighted, in the “+” direction if you are farsighted. If this is not sufficient you may require an optional diopter correction lens. See below.

Point the camera at a bright, plain object such as a white wall when making this adjustment.

Replacing the Diopter Correction Lens

If there is dirt or dust on the lens surface, remove it with a blower or sweep it off gently with a lens brush.

If there are fingerprints or dirt on the lens surface, wipe them off with a piece of clean, soft gauze.

Using solvents could discolor the diopter correction lens frame.

1. Remove the lens supplied with the finder by pulling it downward.

2. Push the replacement diopter correction lens upward into the viewfinder’s eyepiece frame until it clicks into place.

2.11 Adjusting the Strap

Put the neck strap through the mounts and secure it to the buckle as illustrated.

After attaching the strap, pull it and make sure it does not loosen at the buckle.
