Arri Alura 15.5-45mm T2.8 Zoom Lens

Compatible Cameras: Sony F5/ F55/ F3, Arri Alexa, Arri Amira (PL), Red Dragon (PL)   with Adaptor: Sony FS7, Panasonic GH4

Our thoughts

This is a short, wide angle zoom that complements the other two Alura zoom lenses.
It is similar in style but considerably smaller and it has a constant aperture of 2.8.
Due to its lighter weight it’s great for handholding and its 15.5mm wide end extends the scope of the other two.
It is the same film style and impressive build quality.

Note: It is not compatible with the Century 2X extender

The Arri Alura 15.5-45mm zoom lens shares the unique characteristics that have made the existing Alura studio zooms (18-80/T2.6 and 45-250/T2.6) already best-sellers: highest optical quality in a robust housing at an affordable price. While optimized for digital cameras, it is compatible with film cameras and includes the ARRI Lens Data System (LDS).
