Description
xA highly-effective dust and splash resistant structure is built into the lens barrel, with special sealing at the mount connection, focus and zoom rings, and other lens controls.
The tripod socket with 90° click stops, made with a magnesium alloy that is both lightweight and tough, is incorporated to ensure easier changes of shooting position from vertical to horizontal and vice versa. It can be attached directly to an Arca Swiss type clamp.
The L-Mount version of the lens is compatible with the SIGMA TELE CONVERTER TC-1411 (1.4x) and TC-2011 (2.0x). Using a tele converter, the focal length can be multiplied by 1.4x and even 2x, for AF-enabled shooting at ultra-telephoto focal lengths of up to 1,000mm.
TSC is a type of polycarbonate with a thermal expansion rate similar to that of aluminum. By using a combination of TSC and aluminum parts, lenses can be considerably more lightweight without sacrificing durability and operability.
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
