A cine-style lens that covers full-frame sensors, the SLR Magic APO HyperPrime CINE 85mm T2.1 Lens projects a 44mm image circle and is suitable for use with select cameras that have a 6K sensor. It features cine-style focus and iris gears and an internal focus design that allows you to pull focus without the length of the lens changing. This makes it well-suited for use with rod-mounted lens accessories and matte boxes. The 300° of focus rotation provides for precise focus pulls especially when working at close focus. The lens focuses in the industry standard direction and has a 95mm front diameter. The front of the lens does not rotate as you change focus, which may allow for the use of clip-on matte boxes and sunshades (depending on weight), as well as polarizing filters. The lens incorporates an ARRI PL mount that provides a simple, strong, and highly reliable mount. Coverage The lens covers full-frame sensors. Internal Focus The internal focus design allows you to pull focus without the length of the lens changing. This is especially important when working with rod-mounted lens accessories such as follow focus units so that the gears remain engaged as focus changes. The consistent lens length also makes using a rod-mounted matte box simpler, as there is no concern for pushing into or pulling out of the matte box, and you don't need a bellows-style anti-reflection ring. Industry Standard Focus and Iris Gears Built-in iris and focus gears follow industry standards, allowing you to work with optional follow focus units and lens gear motors. 300° of Lens Rotation 300° of focus rotation enables precise focus adjustment, especially as you focus close to the lens.
