Dual Focus Tab Options

The Simera 28mm M-mount offers two focus tab designs to suit diverse preferences:

Infinity-lock Tab:

Ensures stability and prevents lens rotation during installation while maintaining a compact design.

Crescent-shaped Tab:

Offers ergonomic comfort and smooth, single-finger focusing for a better shooting experience.

*Note: Replacing the focus tab requires disassembly and calibration of four 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.
