Scale (16i. Yellow digits, B, 1, 1/2, 1/4 and 1/8 sec. are not coupled.

In the case of light measurement at full lens opening, the meter will be interlocked (coupled) within the ranges given below.
With f/1.2: EV4.5 (f/1.2,1/15 sec.) - EV 17 (f/16, 1/500 sec.) With f/1.4: EV5 (f/1.4,1/15 sec.) - EV 17 (f/16, 1/500 ec.) With f/1.8: EV
5.7 (f/1.8,1/15 sec.) - EV 1 7 (f/16,11/500 sec.)

is beyond the range, even changing of the shutter speed dial within a range from 
1/15 
to 
1/500 
sec., EE photography is impossible.
In the event that you want to give priority to the selection of a lens aperture over a shutter speed because of your specific
photographing purpose, turn the shutter speed dial while looking through the viewfinder and bring the meter needle in line with the
reading of the desired shutter speed. Make sure at all times that the shutter speed dial clicks into position at the calibration of a

desired shutter speed.

DEPTH OF FIELD
When the lens is focused on a subject at some distance, not only the subject but also a certain area around the subject will be
sharply delineated in a photograph, and this area is known as a depth of field and has the following features. 1. The larger the
f-number, the bigger the depth of

field.
2. The farther the distance at which the lens is focused, the bigger the depth of field is.
3.Whenthelensisfocusedonasubject,thedepthoffieldisbiggerforthesectioninfrontofthesubjectthanthatbehindthe

.4. The shorter the focal length, the bigger the depth of field is.

Infrared Film Compensation Mark: 
When infrared film and a red filter are used in taking infrared photographs, read the Distance
Reading 23 aligned with the Distance Scale Index Mark 484 after the lens has been focused as in normal photography and then turn
the focusing ring to bring this reading in line with the Infrared Film Compensation Mark 47 before the shutter button is depressed for a

shot.
