Thypoch Simera-C 21mm T1.5 Compact Full-Frame Wide-Angle Cine Prime Lens - Sony E

The Thypoch Simera-C 21mm T1.5 is the wide-angle member of Thypoch's Simera-C full-frame cine prime series, a family built around a simple idea: cinema cameras have gotten small, so cinema glass should too. It blends the design legacy of classic rangefinder optics with modern cine-lens engineering, delivering a fast T1.5 maximum aperture and true full-frame coverage in a body barely larger than a rangefinder still lens. In Sony E mount the lens measures 78.6mm long and weighs 491g; the native Leica M version is shorter and lighter still at 68.8mm and 472g. Either way, documentary shooters, gimbal operators and solo filmmakers get a genuine manual cine prime that will not weigh down a Ronin 4D, a drone, or a run-and-gun handheld rig.

Optically, the Simera-C 21mm is built from 13 elements in 11 groups, including two aspherical elements, three low-dispersion elements and three high-refractive-index elements, with multi-layer anti-reflective coatings that suppress flare and ghosting in backlit scenes. The rendering is naturalistic rather than clinical: clean chromatic aberration control, natural edge fall-off and a gentle, human-eye-like field curvature wide open. A 16-blade rounded iris - two more blades than the Simera photography line - keeps out-of-focus highlights smooth and circular, free of onion-ring artifacts, while a floating element design pulls the minimum focus distance in to 0.23m (9.05 in) from the sensor plane, unusually tight for a 21mm wide angle and closer than most rehoused rangefinder glass.

Mechanically, the 21mm is an all-metal, anodized aluminum barrel with standard 0.8 MOD focus and iris gears for follow-focus and lens-motor control, plus a long 210-degree focus rotation for precise, repeatable pulls. Its 43.2mm maximum image circle covers full-frame sensors and scales down cleanly to Super 35 and APS-C. Choose native Sony E mount for direct use on Sony full-frame and APS-C mirrorless bodies, or native Leica M mount, which opens the lens up to E, L, Z and RF mirrorless cameras through Thypoch's Positive-Lock adapter series - and, with the M-ARRI Positive-Lock module, to ARRI cinema bodies (ALEXA 35, ALEXA Mini LF and ALEXA 265 unmodified; ALEXA Mini and AMIRA require ARRI service-center modification). A 62mm (M62 x 0.75) front filter thread and a compact 67mm front diameter keep it friendly to standard filters and 80mm matte boxes.

Features

• Fast T1.5 maximum aperture for low-light shooting and shallow depth of field (stops down to f/16)
• 21mm wide-angle focal length with true full-frame coverage (43.2mm maximum image circle); also works on Super 35 and APS-C
• Advanced optical formula: 13 elements in 11 groups with 2 aspherical, 3 low-dispersion and 3 high-refractive-index elements
• 16-blade rounded iris - up from 14 on the Simera photography line - for smooth, circular bokeh and clean specular highlights
• Close 0.23m (9.05 in) minimum focus from the sensor plane thanks to a floating element design - tighter than most rehoused rangefinder glass
• Compact and light for gimbals, drones and the DJI Ronin 4D: 78.6mm / 491g in Sony E, 68.8mm / 472g in Leica M
• Standard 0.8 MOD focus and iris gears with a 210-degree focus rotation for follow-focus and lens-motor control
• Multi-layer anti-reflective coatings suppress flare and ghosting for accurate color in backlit conditions
• All-metal anodized aluminum alloy barrel with dual metric and imperial focus scales
• Available in native Sony E mount or native Leica M mount; the M version adapts to E, L, Z and RF mirrorless via Thypoch Positive-Lock adapters
• Optional M-ARRI Positive-Lock module adds ARRI support (ALEXA 35, Mini LF and 265 unmodified; ALEXA Mini and AMIRA need ARRI service modification)
• 62mm (M62 x 0.75) filter thread and 67mm front diameter for standard filters and 80mm matte boxes
