The innovative design of this lens features an OLED display that shows the focus distance and depth of field, so you can quickly recognize your focus parameters. The performance of the auto focus works quickly and smoothly thanks to the linear motors. Four double-sided aspherical elements within a floating design ensure that anomalies and distortions are controlled throughout the focusing range and contribute to edge-to-edge sharpness and exposure. An anti-reflective T * coating minimizes flare and ghosting for greater color accuracy and increased contrast. Ideal for architecture, landscape and interior photography. This lens has a viewing angle of 82 degrees with a minimum focusing distance of 20 cm for producing creative angles. The lens is dust and weather resistant so that you can use it in various weather conditions.
