The iris had two functions - as a means of checking the depth of field and as an extinction meter. The meter is placed on the viewing lens of the camera. The iris is closed until the mid tones become indistinct, the shutter speed and aperture pairs can then be read. There are two scales one for open air use the other for artificial light. Only one film speed was shown. Early models are black later a black and chrome finish was used. The maximum aperture was also increased to f2.8.
