The Sigma 135mm F1.4 DG Art full-frame lens features a maximum aperture of F1.4, delivering exceptional expressive capabilities for portrait photography. Its unrivalled large bokeh and stunning resolution creates an extraordinary sense of depth and dimensionality. The natural perspective and moderate shooting distance unique to 135mm lenses, combined with 13-blade diaphragm, make the subject stand out to give rich bokeh. Precision optics Four large FLD glass elements are positioned, along with strategically placed high-dispersion glass elements to thoroughly suppress axial chromatic aberration, which tends to be more pronounced in large-aperture telephoto lenses. As a result, the lens delivers crisp subject detail even when shot wide open, making full use of the exceptionally shallow depth of field unique to a 135mm F1.4. Floating focus system A floating focus system moves the two focus lens groups independently, ensuring consistently high resolution across the entire focus range. Designed to minimize flare and ghosting Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology and Sigma’s Super Multi-Layer Coating. High backlight resistance enables clear and sharp images under any lighting conditions. Fast, precise autofocus Each of the two focus groups is driven by its own HLA (High-response Linear Actuator), forming a dual HLA system. By incorporating two distinct types of HLAs, each optimized for the movement range of a focus group, the dual HLA system ensures both the high thrust needed for large-aperture telephoto lenses and fast, precise AF performance. This allows even fleeting expressions and fast-moving subjects to be captured with exceptional reliability. Shooting assist functions The lens is equipped with an AFL button in two locations, which can be assigned to a range of functions via the menu on selected cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch and a click switch to turn the click on and off. Excellent build quality Metal components such as aluminium and magnesium alloys are combined with engineering plastics like TSC, strategically placed throughout the construction. This balances the durability required to support the optical system of a large-diameter lens with the lightweight design necessary for comfortable handling. Dust and splash-resistant structure plus water and oil-repellent coating In addition to a dust-and splash-resistant structure, the front element of the lens features a water-and oil-repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments. Arca-Swiss compatible tripod socket The lens comes with a lightweight yet robust tripod socket made of magnesium alloy, compatible with Arca-Swiss clamps. It provides excellent stability during studio sessions and extended shooting, helping photographers stay focused on their creative expression. The tripod socket is also removable and can be replaced with the supplied protective cover. Supplied hood with a button-type locking mechanism The supplied hood is equipped with a button-type locking mechanism for secure attachment and removal. It is constructed from CFRP, a polycarbonate material reinforced with carbon fibre, making it both lightweight and durable.
