The Mark Vb Directors viewfinder will give you readings for a number of Digital sensors within 10% of a given lens focal length. To achieve this, set the Aspect ratio ring to 16X9 and read the 35mm window. The finder is now set for Super 35 and this setting is also true for the following digital camera sensors: Arri Alexa, Sony F35 PL, Red Epic-X, Red One, Canon 7D, Phantom HD Gold.
Manufactured by Alan Gordon Enterprises, the Mark Vb is the latest version of the Academy Award Winning Mark V and continues to be the choice of Film and Video makers worldwide. The Mark Vb has all the features of the Mark V plus new markings on the Aspect Ratio ring, making it easer to read for both film and video use. We also eliminated the 1/2 " video window and replaced it with the current video chip standard of 2/3." Film sizes and video formats are color-coded for quick reading.
