USED SIGMA 135mm F1.4 DG Art for L-Mount

Product Features

• The biggest feature is the extremely large bokeh created by its effective aperture. The natural perspective unique to 135mm and the overwhelming amount of bokeh make the subject stand out, enabling three-dimensional portraits that can only be rendered with this lens.
• Thoroughly corrects chromatic aberration, which tends to occur with telephoto lenses, achieving clear bokeh without color bleeding. Furthermore, the design suppresses vignetting, producing natural, near-circular bokeh even in the periphery, allowing for shooting that takes advantage of the wide-open aperture.
• 13 aperture blades to maintain circular bokeh, and pursuit of high precision in aspherical lens manufacturing. Beautiful and natural bokeh is achieved through the fusion of Sigma's advanced optical design technology, cultivated over many years of developing F1.4 prime lenses, and the manufacturing technology of our Aizu factory.
• In addition to four large-diameter FLD glass elements, highly dispersive glass elements are effectively arranged to thoroughly correct axial chromatic aberration, which is noticeable in large-aperture telephoto lenses. It clearly depicts subject details from wide-open aperture, allowing you to actively utilize the extremely shallow depth of field unique to 135mm F1.4.
• By employing a floating focus mechanism that moves two focus lens groups independently, high resolution is maintained throughout the entire focus range.
• Flare and ghosting are significantly suppressed thanks to cutting-edge simulation technology and Super Multi-Layer Coating. High backlight resistance ensures clear and transparent rendering under any lighting conditions.
• Features Dual HLA (High-response Linear Actuator) that drives each of the two focus groups with linear motors. By appropriately placing two types of HLA optimized according to the movement amount of the focus groups, high thrust required for large-aperture telephoto lenses is secured while achieving high-speed and high-precision AF.
• Equipped with AFL buttons in two locations that can be assigned arbitrary functions. In addition to the aperture ring, it also features an aperture ring lock switch and a click switch that can toggle the click ON/OFF.
• The dust- and moisture-resistant body, along with a water-repellent and oil-repellent coating on the front element of the lens, allows for worry-free shooting even in harsh outdoor environments.
• To balance robustness and lightness, metal parts such as aluminum and magnesium alloy are used in appropriate locations along with engineering plastics like TSC. It boasts the high rigidity, durability, and build quality characteristic of the Art line.
• Includes an Arca-Swiss compatible tripod mount made of lightweight yet rigid magnesium alloy. It provides excellent stability when using a tripod in the studio or for long shooting sessions, supporting a shooting environment where you can concentrate on expression. The tripod mount can also be removed and replaced with the included protective cover.
• Includes a dedicated hood with a button-type lock mechanism for secure and stable attachment and detachment. Made from CFRP (Carbon Fiber Reinforced Polymer), which contains carbon fiber in polycarbonate, it achieves both lightness and high durability.
