  • Exceptional edge-to-edge sharpness from 13 elements in 11 groups
  • Ultra-wide 21mm perspective for expansive landscapes and architecture

  • Precise tactile focusing with focus tab down to 9.1
  • Clicked or de-clicked aperture ring for silent video control

Wide-angle prime for Leica M

The DZOFILM Simera 21mm f/1.4 is a manual-focus wide-angle prime built for Leica M-mount cameras. Its 21mm focal length suits landscape, architecture and environmental portrait work where an expansive perspective is required. Photographers who prefer tactile control will appreciate the focus tab and the aperture ring that switches between clicked and de-clicked operation. This lens is not for shooters who need autofocus or electronic aperture communication.

f/1.4 to f/16 range with 14-blade iris

The maximum aperture of f/1.4 provides strong low-light performance and shallow depth of field for subject isolation. A 14-blade iris produces rounded bokeh and defined highlights across the aperture range down to f/16. Minimum focus distance is 9.1 inches, allowing close-up detail work alongside wider scenes. The range runs out for photographers who need faster than f/1.4 or who rely on electronic exposure coupling.

13-element, 11-group optical formula

The design uses 13 elements in 11 groups including two aspherical, three extra-low dispersion and three high-refractive index elements. This combination minimises chromatic aberration and distortion while delivering edge-to-edge sharpness. Buyers who need a simpler, lighter construction or who require autofocus confirmation should look elsewhere.

Questions about this item

Will this 21mm f/1.4 lens mount directly on my Leica M body without an adapter?

Yes, it is built with a native Leica M mount so it attaches directly to any Leica M camera.

How can I verify the 14-blade iris is giving the smooth bokeh the specs promise?

Shoot wide open at f/1.4 against point light sources; the highlights should render as clean, round discs with no onion-ring artefacts.

What accessories come in the box and what must I purchase separately?

The lens includes front and rear caps; a dedicated hood and filters are sold separately.
