Cinema lens front diameter chart

Updated 18 Oct 2026

Front diameter decides which clamp-on matte box adapter or reduction ring you need. Many cine prime sets share one front diameter across the set so you can swap lenses without changing the matte box back.

In the registry: 95mm (51 lenses), 114mm (47 lenses), 80mm (32 lenses), 110mm (10 lenses), 85mm (8 lenses), 90mm (7 lenses), 87mm (6 lenses). Figures are as listed on each item's GEARMATH page, which records manufacturer specifications. Check the manufacturer before you rely on a number.
