Arri Alura 45-250mm

The Arri Alura 45-450mm is the long version of the 18-80mm and is very similar in style. This is a really solid professional film style lens. Originally built to complement the Alexa it’s very nicely put together and also (unusually!) the focus scale is very accurate.

The lens is clean and sharp and is marked up in T stops, has a 2.6 aperture throughout its zoom range and has minimal breathing. This is a heavy professional film lens and therefore needs support, we supply it with supports for 15mm or 19mm bars.

Although people have been known to handhold cameras, with this lens you need to be pretty fit!

ARRI and FUJINON have joined their extensive expertise to create a completely new family of modern cine zooms. Using the latest in optical design technology and innovative manufacturing techniques, the ARRI Alura Zooms combine the highest optical performance with an amazingly small size, weight and price. They are available as Studio zooms for use on a tripod or crane with a wider focal range, or as lightweight zooms which are significantly smaller and lighter in exchange for a reduced focal range.

All Alura Zooms’ color characteristics, as well as their handling, are matched to existing prime lenses in ARRI’s outstanding repertoire
