Make sure you have the right tool to capture that vast landscape or tight architectural space by picking up the DT 11-18mm f/4.5-5.6 Lens from Sony. Designed specifically for Sony's APS-C A-mount DSLR cameras, it provides an equivalent zoom range of 16.5-27mm for ultra-wide imaging. It uses a variable f/4.5-5.6 maximum aperture to keep size and weight to a minimum while it incorporates various specialized elements to minimize aberrations and improve sharpness and clarity. Also, it has an internal focus mechanism that helps speed up autofocus performance to the minimum focus distance of 9.8". Additionally, it has a seven-blade circular diaphragm for smooth bokeh and it has a front filter diameter of 77mm.
