Leica Cine MacroLux +1 is no ordinary Diopter, as we saw at NAB. You could do the almost unthinkable: stack 3 of them together (to achieve +3) and still maintain great image quality. Thee MacroLux is a spherical doublet that exhibits no spherical aberrations, no color fringing, and almost no light loss. Its coatings are color matched to the rest of the Summilux-C and Summicron-C lens series.
The MacroLux clamps onto the front of 11 of the 12 Summilux- C lenses (all except the 135 Summilux-C) and 11 Summicron-C. at’s because they all share the same front diameter: 95 mm. The MacroLux will also work on other lenses with 95 mm front diameters, like ARRI/ZEISS Ultra Primes (16 – 135), ZEISS Compact Zooms (28-80, 70-200) and ARRI/ZEISS Master Anamorphics (35 – 180).
The MacroLux is secured with a two-sided thumbscrew that lets you work from either side of the camera. Both the front and the rear are 95 mm diameter, letting you stack additional MacroLuxes for greater proximity and to use the same mattebox accessories.
