Carl Zeiss 1839-792 (1839792, 1839 792, 1839/792) master macro lens LWZ.2 EF - feet;Close-Up on Quality;For those who want the ultimate in image quality for table top cinematography, product shots, close-up inserts on feature films or any other applications that require a macro lens, the Master Macro 100 delivers images of breathtaking beauty. The Master Macro is a joint development of ARRI and Carl Zeiss.;100 mm macro lens with 1:1 magnification ratio;Novel optical design optimized for close-up work;Wide T-stop range: T2.0 (infinity) / T4.3 (close focus) to T32;Based on Master Prime technology;High resolution, high contrast and dramatically reduced flare;Long focal length allows greater distance to subject;Built-in Lens Data System (LDS);Super Color Matched to Master Primes, Ultra Primes, Ultra 16 lenses, Lightweight Zoom LWZ.2;Application;Designed for the ANSI Super 35 image format, the Master Macro 100 can be used on any PL mount 35 mm film and single sensor digital camera. In addition it can be used on PL mount 16 mm film and single sensor 16 mm or 2/3” format digital cameras.;With a 1:1 magnification ratio, a maximum aperture of T2.0 and an optical design developed specifically for macro work, the Master Macro delivers phenomenally sharp and contrasty images with vibrant colors for extreme close-ups of the highest visual quality.;The use of aspherical lens surfaces and exotic glass types with anomalous partial dispersion greatly reduces chromatic aberration (color fringes). Modern optical design techniques ensure the optimal light path for reduced stray light and minimized geometric distortion, another feature the Master Macro 100 shares with the Master Primes.
