28mm f/1.4 ASPH.
Redefining Environmental Portraits
The Simera 28mm redefines environmental portraiture with its balance of creamy bokeh, natural tones, and cinematic depth. Featuring a 14-blade diaphragm for rounded highlights and artistic starbursts, along with a 0.4m minimum focus distance, it captures both expansive scenes and intimate details. With exceptional sharpness, smooth focus transitions, and precise chromatic control, this lens preserves the warmth and emotion of every moment.
Dual Focus Tab Options
The Simera 28mm M-mount offers two focus tab designs to suit diverse preferences:
Infinity-lock Tab:
Enhances stability by preventing lens rotation during installation, ensuring secure handling.
Crescent-shaped Tab:
Ergonomically designed for a comfortable grip, enabling smooth, single-finger focusing for seamless operation.
*Note: Replacing the focus tab requires disassembly and calibration of several internal components.
To ensure optimal optical performance and mechanical stability, user replacement is not recommended.
Superior Optics, Exquisite Details
The lens includes 1 aspherical element, 1 extra-low dispersion (ED) element, and 3 high-refractive-index (HRI) elements, paired with a floating lens group to deliver unparalleled sharpness from infinity to its 0.4m minimum focusing distance

Retro Elegance,
Modern Innovation
Crafted from anodized aluminum alloy, the lens body features a depth-of-field scale with a distinctive red dot design, paying homage to iconic 1950s aesthetics. This enables swift hyperfocal shooting for street photography.
The click/declick aperture mechanism facilitates seamless transitions between still photography and video shooting.
A tactile resistance point at 0.7 meters on the focus ring alerts users to switch from rangefinder coupling to EVF focusing.
