Kowa Cine Prominar 20mm T2.6

We don’t have a vetted photo of this one yet. Own a copy? Send us a packshot and we’ll credit you.

One of two T2.6 lenses in the set. Super 35 coverage only. Japanese cine primes from the 1960s with single-layer gold-toned coatings that produce warm amber flares and reduced contrast; they sharpen nicely one stop down. Specs are for the TLS rehousing.

What it goes on

The common rental form is the TLS rehousing in PL with 110mm fronts; original barrels are small, light (roughly 1–2 lb) and have 87mm fronts, which some operators still prefer for handheld and Steadicam. Originals are usually found PL-converted from Arri Standard or Mitchell mounts.
