Put it all together in a lens that is surprisingly compact and lightweight and you have a winning combination: the SEL50F18. The large maximum aperture and Optical SteadyShot are worthy features in their own right, but working together they make it possible to shoot crisp, clear images under low-light conditions that would be beyond the capabilities of a conventional lens. The F1.8 maximum aperture and a circular aperture design also join forces to create gorgeous defocusing effects. Add responsive, quiet autofocus and aperture operation, and you have a lens that is ideally suited to shooting movies as well as stills. • Weight (approx): 202 g • Dimensions (Dia.

The SEL30M35 has been designed to offer versatile, high-performance macro capabilities in a lens that is compact, lightweight and easy to use. At the time of release the SEL30M35 is, in fact, the lightest interchangeable 1:1 macro lens available anywhere! It is a true 1:1 macro lens with a 2.4 centimeter minimum working distance that allows tiny subjects and details to be rendered with excellent resolution and contrast. But it also functions as an excellent "normal" lens for day-to-say shooting, and a smooth, quiet internal lens drive system makes it suitable for shooting movies as well. The SEL30M35 is a great choice for a second lens that will let you explore the world in creative new ways. A dedicated lens hood that won't get in the way when shooting close is included. • Weight (approx): 138 g • Dimensions (Dia. X L): 62 x 55.5 mm • Max. magnification ratio: 1x 63
