This newer one features aluminum construction, improved lens coating, and a rubber ring around the metal bayonet that prevents water and dust from entering the lens through the rear. The only other difference is a slight redesign in the appearance of the lens. It's all black, without a red stripe around the top.AF/MF Switch & Custom Function Button An AF/MF selector switch allows you to quickly toggle between autofocus and manual focus modes. Next to this selector switch is a customizable function button that can be assigned a shortcut operation or used to pull up a function menu.Fast f/1.8 Aperture & 7-Blade Iris The fast f/1.8 aperture allows increased control over depth of field, enabling you to isolate a subject from the background. It allows you to shoot with higher shutter speeds in low-light environments and to achieve a soft blur effect. Additionally, a 7-blade diaphragm lets you capture smooth bokeh and circular highlights. With the aperture appropriately reduced, the 7-blade diaphragm also allows you to capture photos with star effects.
