Linear Iris

Linear Iris Diaphragms


Our linear iris diaphragms enable a 1:1 ratio to produce a true, equally distributed, F Stop scale.


By nature iris diaphragms are inherrently non-linear devices - meaning their outer ring moves disproportionatly to the size of the aperture being adjusted.


To address this non-lenearity we've employed a clever design, ensuring the rotational movement distance always directly corresponds with the aperture size.


The accuracy of your aperture control is no longer compromised by compressed scales.
