For the serious photographer, the Sony Planar T* FE 50mm f/1.4 ZA Lens is a must have for any collection. Perfect for a wide range of uses including portrait, wedding, detail shots, beautifully manipulated depth-of-field shots and more, the Sony Planar T* FE 50mm f/1.4 ZA Lens has a fixed focal range of 50mm. Since the focal range is fixed, this prime lens allows for a significantly wider aperture range--which allows for depth-of field focus manipulation and wonderful bokeh effect shots where the subject-matter is crisp and clear while the background is presented as a beautiful blur. This high-performance Zeiss constructed lens features a large f/1.4 aperture as well as breathtaking contrast and resolution throughout every image. High Quality Optical Design Incorporating a double-gauss design constructed of two aspherical elements, including one precision AA (advanced aspherical) element, the Sony Planar T* FE 50mm f/1.4 ZA Lens employs an ED (Extra-low Dispersion) glass element to suppress field curvature and distortion. It does so while maintaining outstanding edge to edge resolution and contrast from the widest aperture at any focusing distance. f/1.4 for Optimal Versatility The Sony Planar T* FE 50mm f/1.4 ZA Lens' maximum aperture of f/1.4 can create images with shallow depth of field and smooth, beautiful bokeh. It's also possible to capture amazing images at high shutter speeds, even in low light environments. When you really want to push your creativity, the lens can also be stopped down to create an extended depth of field. 11 Circular Aperture Blades For natural, beautiful bokeh highlights, the Sony Planar T* FE 50mm f/1.4 ZA Lens incorporates 11 blades instead of 9 which takes bokeh quality to a whole new level. This lens yields natural-looking highlights in the out-of-focus areas--enhancing the overall atmosphere of the image and provides a gentle sense of depth unlike ever before. Excellent Color and Contrast While Zeiss lenses are renown for delivering outstanding color reproduction and contrast, the Zeiss T* coating is an essential contributing factor. The coating works by effectively suppressing spurious reflections that can degrade overall image quality--flare and ghosting are minimized for enhanced color and contrast to give images a deep, three-dimensional feel. SuperSonic Wave Motor With a focus drive handled by a ring drive SSM (Super Sonic Wave Motor) system, the Sony Planar T* FE 50mm f/1.4 ZA Lens can position the heavy focus group required by large aperture lenses. Whether you're shooting stills or movies, the lens operates with speed and precision--fast, accurate focus is essential to bring out the full performance potential of high-resolution camera bodies. Convenient Fingertip Control The Sony Planar T* FE 50mm f/1.4 ZA Lens puts aperture control right at your fingertips. Incorporated into its design is an aperture ring allows which is enabled or disabled by an aperture click switch. For convenient manual autofocus selection, the lens also features a focus mode switch. Dust & Moisture Resistant Dust and moisture-resistant sealing design of the Sony Planar T* FE 50mm f/1.4 ZA Lens offers extra protection for your investment and ensures reliable operation in even the most challenging environments. Take pictures with confidence in light rain or windy conditions knowing that your lens performance won't let you down. ?
