           SPECIALITY LENSES



           Conventional lenses give you a wide range        but they will inspire you to try out new
           of shooting options, but it is interesting to try   creative approaches. Some of the effects
           more specialized ones occasionally. These are    possible with speciality lenses can also be
           the sorts of lenses that you wouldn’t want to    created in postproduction, but you will
           use every day, but when you do, they will give   achieve a better-quality image using the right
           you the chance to experiment with your own       lens in the first place, and, perhaps more
           style of photography. They are not necessary,    importantly, it will also be more rewarding.



                             TILT-SHIFT                                        FISHEYE





















                           A tilt-shift lens lets you angle (tilt) the   A fisheye lens, also known as an ultrawide or superwide
                           front lens element or move it up and   lens, is an extreme form of wide-angle lens. It captures a
                           down or left and right (shift), relative    very wide image that is highly distorted and produces an
                           to the camera body. Tilting controls               exaggerated curvature of straight
                           image sharpness by altering the                    lines. The resulting image is circular,
                           angle of the plane of focus. Tilting               though many modern fisheyes can
                           up will increase blur, whereas tilting             produce rectangular images with
                           downwards will increase sharpness.                 a diagonal 180° angle of view.
                           Shift lets you keep your camera parallel           (The angle of view will also depend
                           to your subject, which minimizes                   on the camera’s crop factor.) Use a
