A moulded glass aspherical element corrects for sagittal coma flare and enables full use of the fast f\/1.4 maximum aperture with maintained sharpness and clarity. This design also works to minimise vignetting, colour blur, and other distortions help to produce natural and pleasing bokeh for selective focus and shallow depth of field techniques. By reducing these aberrations, this lens is also well-suited to astrophotography or other situations with point-light sources due to its ability to suppress blur near the edges of the frame.\u003cbr\u003e\r\n\u003cbr\u003e\r\n\u003cstrong\u003eSpecial Low Dispersion Glass Elements\u003c\/strong\u003e\u003cbr\u003e\r\nThree SLD (Special Low Dispersion) glass elements have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range.
