You can enjoy high performance with low noise in a variety of shooting situations. &nbsp; &nbsp;<br /><br /><b>Ultra Low Dispersion (UD)</b><br />Glass Canon&#39;s Low Dispersion technology is engineered to reduce chromatic aberrations, eliminating the tendency of light of different colors to focus to different points at the image plane.&nbsp; This means your images will come out crisp and clear, with less of a chance of defracting light into an unwanted rainbow of colors.&nbsp; Take shots exactly like you want, without any flare-up or blurring.<br /><br /><b>ASPHERICAL DESIGN </b><br />Canon&#39;s aspherical lens design creates a more complex surface profile.&nbsp; This helps to greatly reduce spherical and other optical aberrations.&nbsp; The design further ensures consistent imaging performance throughout the entire focal range, while delivering incredible sharpness up to the periphery of the image.&nbsp;<br /><br /><b>ANTI-REFLECTIVE COATING </b><br />The Canon anti-reflective coating is an optical design feature which ensures superior clarity and image brilliance, even in poor or unfavorable lighting conditions.&nbsp; Canon applies the anti-reflective coating through a special process, layering the lens surface in order to substantially reduce unwanted flare or ghosting.&nbsp; This process helps to ensure incredibly rich image contrast and true color fidelity.&nbsp;<br /><br /><b>MANUAL FOCUS</b><br />Manual focusing means you have all the control at the end of your fingers.&nbsp; Canon lenses feature a specially designed ergonomic construction that is noticeable at first touch.&nbsp; The large rotation angle of this lens guarantees precise focusing.&nbsp; The mechanism moves super smoothly and without extra play, furthering the intuitive interaction along the focal plane.&nbsp;<br /><br /><b>ADVANCED APERTURE DESIGN </b><br />With Canon lenses you can create stunning Bokeh effects, thanks to the finely tuned features and advanced optical design.&nbsp; By keeping the background intentionally blurred, additional focus is created on the subject of an image.&nbsp; The uniquely engineered diaphragm blades of this lens, along with the virtually circular aperture, deliver stunning renditions of highlights the back and foreground.&nbsp;<br />&nbsp;</p>
