3. Shooting 3-5 Focusing
The image contrast will become noticeably sharp when the two
images superimpose precisely. That is the point where the lens criti-
cally focuses on the subject.
3. Split image focus:
Split-image is an image divided into upper and lower halves. Human
vision naturally perceives the most critical image matching when
comparing the alignment of edges in a split image. The optical sys-
tem of the Bronica RF 645 is so constructed that the sliding side
image in the focusing frame is decisively sectioned at the upper
and/or lower edge of the focusing frame. By aligning the edge of the
moving image with the connecting edge (or lower part) of the sta-
tionary image, the lens can be very precisely focused on the subject.
3. Shooting 3-6 Automatic parallax compensation
3-6 Automatic Parallax Compensation
The view frame of the Bronica RF 645 finder automatically compensates
for the parallax between the shooting lens and the viewfinder angle by
compensating its position and viewing frame relative to the focusing
distance. When mounting a 65mm or 100mm lens, focus on a moderate-
ly distant object. The angle of view of the bright frame in the viewfinder
will shift toward the lower right hand corner of the viewfinder frame.
The area enclosed by the bright frame, when focus is achieved repre-
sents the area to be photographed.
4. Other Features 4-1 Multiple Exposure
4-1 Multiple Exposures
This feature enables the camera to expose multiple images on one
picture frame.
1. Firstly, take an image that forms the base of multiple exposures.
2. Looking through the viewfinder, make sure the LCD panel is activat-
ed. Then, press the ME button on the back of the camera. Note: The
ME button does not work if pressed while the LCD panel is not acti-
vated. Press the shutter release button lightly and operate the ME
button while the LCD is active.
