Aperture adjustment ring mark

Each number between 4~22 is 1 stop (1 EV) away from the next number. Brightness can be set more precisely by using the stop setting in between, such as the 0.5 stop between. 2.8 and 4.

e.g. 5.6 and 8 are 1 stop (1 EV) away from each other.

Set a brightness between 5.6 and 8, which is 0.5 of a stop (0.5 EV) between the two

Camera settings

The aperture of the 12mm 1:2.0 NCS CS lens for Canon M, Fujifilm X, Samsung NX, and Sony E, MFT is not geared to the Cameras.

If the brightness value is set to above 8, the user may have difficulty in setting the correct focus when viewing a subject through the camera viewfinder, therefore focus on the subject by fully opening the aperture when attaching this lens to the camera, and then setting the depth of focus and brightness you want to express prior to shooting.
