GL Optics Pentax SMC 67 45mm T4.1
(INSERT SINGLE HERO IMAGE HERE - other images below in media section)
Summary
Rehoused Pentax SMC 67 lenses redefine medium format for cinema. Paired optionally with a Kipon .8x focal reducer, they retain full Alexa 65 sensor coverage—unlike our Mamiya 645, Hasselblad HC, and Contax 645 lenses. This pairing unlocks nearly a stop of extra light, making these lenses faster and more versatile. With their legendary rendering, shallow depth of field, and enhanced low-light performance, they offer an expansive canvas for 65mm cinematic storytelling.
