Note the new designation "b"--This is the newest version of the industry standard view finder of the professionals. You may adjust the viewfinder to the aspect ratio that is appropriate for your film or video application. Available aspect ratios are: 1.33:1 standard TV, 16x9 HDTV, 1.85:1 standard 35mm ratio and 2.40:1 anamorphic wide screen, also known as Panavision or Cinemascope.
12-1 Zoom Range. Focal lengths covered for the various film formats are: • 16mm film: 8.5-100mm • Super 16 film: 10.5-125mm • 35mm film: 18-200mm • 35 Anamorphic film: 35-420mm • Video 2/3": 8.5-75mm
There are several changes from the old Mark V viewfinder. New markings on the aspect ratio ring make it easer to read for both film and video use. However, the 1/2" video window has been replaced with the current video chip standard of 2/3". Film sizes and video formats are color-coded for quick reading.
FAQ: John, I wish the Mark Vb had all the video markings. Is there a simple work-around for this? ANSWER: Yes there is. On any viewfinder that has 2/3" but not 1/3" markings, all you have to do is half the resulting number. If you're shooting with a 1/3" camera, use the 2/3" setting and just divide the resulting focal length by two. It's the same thing as having a 1/3" viewfinder.
