The MasterBuilt ULTRA65 Series is designed for true Large Format (65MM 5-Perf Film & Digital). The entire ULTRA65 Series maintains the MasterBuilt character with added vintage feel. Initially designed for Large Format Cinematography, the ULTRA65 Series offers a refined image that draws the eye with enhanced three dimensionality and structure. The 4 focal lengths (21MM T1.8 / 29MM T1.8 / 40MM T1.8 / 65MM T1.8) act as excellent companions to the Classic and Soft Flare Series, adding the intricate sizes cinematographers need.
