Designed to achieve 50 line pairs/mm resolving power It is not easy to achieve spatial frequency of 50 lines pairs per millimeter at a lens's widest aperture, but that is Sony's baseline for G Master design. Unprecedented resolution and other demanding design parameters yield outstanding reproduction of the most detailed subjects and scenes with superior contrast throughout every frame. G Master resolution is simply the highest in its class. Previously unattainable surface precision Built with three aspherical elements including a newly developed and essential ingredient for astonishing resolution ? is a new XA (extreme aspherical) lens element with better that 0.01?micron surface precision. The extremely precise XA element reduces aberration and delivers the ultimate resolution throughout the entire zoom range and aperture range, as well as from corner to corner of all image files. Constant F1.4 max aperture maintains exposure and depth of field Constant F1.4 max aperture maintains exposure and depth of field regardless of the focal range you choose to zoom to. When changing your aperture to defocus the background, the areas out of the focal plane appear blurred. This ?bokeh? effect of the blurred background can be enhanced with circular aperture blades used in this lens. 11?blade circular aperture contributes to gorgeous bokeh Complementing the performance of the XA element are the first 11?blade circular aperture ever implemented in an a lens, and exacting spherical aberration adjustment for each individual lens. The result is enchantingly soft?edged bokeh that is a hallmark of the Sony G Master series. When changing your aperture to defocus the background, the light sources appear blurred. This ?bokeh? effect of the blurred background can be enhanced with circular aperture blades used in this lens.
