***** **********Best Quality Guranteed. *****7 Elements in 6 Groups. Ideal Aperture with 13 Diaphragm Blades*****F 1.1
Large Aperture: Excellent color balance and optimization, provides a smooth, natural transition between the focus object and the bokeh in the image. The ideal depth of field and fascinating background blur will be achieved with a wide aperture. *****Superior Optical DesignAdopting high refractive glasses of index 1.9 in the 6 groups of 7 elements lens structure based on the sonnar formula, the light transmittance is greatly improved in 50mm F 1.1 lens. This lens design ensures distortion-free images with appropriate brightness, superb resolution and color rendition. *****Multi-layer of
High Permeability Optical Coating: With seven layers high quality optical coating on the lens, the flare, ghost and chromatic aberration are greatly minimized in images. The image quality is greatly improved.
