Rolleiflex Standard

The focusing hood opens by pulling the stopper at its back.
The magnifier can be pulled up to make use (shown in the right picture).
When closing it, restore the magnifier first, and fold the side hoods, and then back and the front last.
The sport finder is set by raising the outside frame of the hood front (shown in the left picture).
In addition, there is the depth of field scale at the hood back, and the scale for the shutter speed and the aperture value at the camera back.
