ARRI Alexa Mini 4K 4:3 35mm Digital Film Camera with 1:2.35 anamorphic licence
Consider also Alexa Mini 4:3 anamorphic camera with RAW licence
Please read VMI’s comparison article: Alexa Mini or Amira? (or why I must have a Mini because it’s newer and better isn’t it?…no wait….)
Read VMI's article: WLCS Systems, All you need to know to explore the question of how to choose between the various systems and to introduce the range of WLCS systems which VMI arguably considers the best in their field and explain why we think that they work very well in given scenarios.
Lenses
Cooke S6i anamorphic PL 2x prime lens set consisting of 5 x lenses: 32mm/T2.3, 40mm/T2.3, 50mm/T2.3, 75mm/T2.3, 100/T2.3.
Precision anamorphic lenses created by Cook with the legendary 'Cooke Look'.
The Anamorphic /i lenses offer superb optical and mechanical performance. Distortion, veiling glare, flares, and all aberrations are controlled at all apertures over the whole field of view. Like all Cooke S4/i, 5/i and miniS4/i prime lenses, the cam focus mechanism allows for smooth focus adjustments. Modular construction increases ease of maintenance and serviceability.
Further VMI Compatibility Tests
In tests, we have put the widest Cooke anamorphic (32mm) on an Alexa 4:3 and it doesn’t vignette with either the ARRI LMB 15 or the ARRI LMB-25 clip-on matte boxes.
It doesn’t vignette with the x2 PL extenders either.
