Curvilinear perspective for unique, expansive images Crisp image quality throughout the focus range Four selectable internal filter settings

Once a scientific tool but now a favorite of creative photographers, fisheye lenses forgo the restraints of rectilinear perspective—the complex “correction” that is required to keep straight lines looking straight—to deliver expansive images that cover an extremely wide angle of view with curvilinear perspective.The SAL16F28 provides an extremely wide 180° angle of view on 35mm full-frame format

Fixed focal length lenses, commonly known as "prime lens" or simply as "primes," can complement your photographic vision in a number of ways. Although most of the focal lengths offered are also available with zoom lenses, some special-purpose lenses are only available as primes: fisheye lenses and most true macro lenses are examples. And since the optical path only needs to work at one focal

length, it can be optimized to deliver a level of optical performance that is a cut above the average zoom. But many photographers like working with a fixed focal length simply because it always gives them the same angle of view and perspective, making it easier to pre-visualize what the camera will see and thus providing the most consistent, intuitive shooting experience.

cameras (110° on APS-C format cameras). In addition to eye-catching interpretations of reality, it offers extended depth of field so that you can capture huge vistas in which everything from 20 centimeters to infinity is sharp, even at maximum aperture. Since the bulging front element and wide angle of view prevent the use of external screw-in filters, four selectable internal filter settings are provided: normal, O56 monochrome, B12 red reduction and A12 blue reduction.
