The Simera 28mm has a large aperture of F1.4 and a 14-blade aperture that creates a stunning bokeh that sets motifs perfectly apart from their surroundings and creates a fascinating sense of space. With a gentle focus roll-off, they create a visual aesthetic that transcends the boundaries of ordinary perception and generates poetry with each triggering. The Simera 28mm features high refractive index (HRI) lens elements and an aspherical lens that precisely correct sharpness and spherical aberrations. With a minimum focusing distance of 0.4 m, the Simera 28mm allows the user to discover the subtleties of the subject with exceptional detail. The subtle resistance at 0.7m on the focusing ring provides tactile feedback to intuitively indicate when the finder can no longer focus and instead the EVF (electronic viewfinder) should be used for optimal focusing accuracy.
