For manual focus lens tooth rings must be set up. SUBAL avoids the fastening with screws - and therefore deformation and damage of the lens with precise adjustment
This focus gear enables manual focus for the Sigma 15mm F2.8 EX DG Diagonal Fisheye lens via the focus/zoom knob when used with Subal housing.
