Tokina OPERA 50mm F1,4 for Nikon F mount

With the debut of 50mm F1.4 FF Tokina is launching a new series of next generation, premium full-frame lenses for high-end DSLR cameras called "opera" series. The new series is designed to perfectly match recent high-resolution full-frame DSLR cameras that demand the highest quality optical designs. In order to effectively suppress chromatic aberrations and deliver sharp edge-to-edge images at all apertures, the opera 50mm F1.4 FF optical construction includes 3 lens elements molded from SD (Super-low Dispersion) glass and one aspherical glass element in the rear-focus lens group. The lens incorporates a 9-blade, round-shaped diaphragm for naturally beautiful bokeh. Tokina also incorporates an electric diaphragm specific to the Nikon mount for more accurate and precise aperture control. Fast and quite AF along with superior optical performance at all apertures and focus points makes this lens suitable for a variety of photographic genres and scenes. The newly developed, Tokina ELR (Extremely Low Reflection) Coating was engineered to specifically target the visible light spectrum as it enters and passes through the lens. This drastically reduces the reflection ratio when compared to traditional Tokina lens coatings. This results in dramatically reduced ghosting and flare when shooting in challenging lighting conditions especially when strong light sources are within the image.The lens employs the latest advancements in dust-resistance and weather sealing targeting 8 areas in the lens construction most vulnerable to dust and water penetration. When coupled with a dust and weather sealed DSLR camera, the lens will not let you down even in adverse weather conditions. To ensure fast and accurate AF, the opera 50mm F1.4 FF incorporates a high-speed, ring-shaped ultrasonic motor for near-silent operation. This provides photographers and filmmakers a valuable tool when speed and quiet are critical features to capturing their vision.The BH-726 lens hood included with the opera 50mm F1.4 FF has a special filter window incorporated into the design. When the BH-726c window is removed from the hood the user has access to the filter allowing them to rotate polarizer or other rotation type filter.
