[BSC Expo 2023] Impression Filters - ARRI

ARRI, a leading camera and lighting equipment manufacturer, unveiled its newest line of impression filters for the Signature Prime lens at the BSC Expo 2023. The filters, which are magnetic and attach to the back of the lens, come in four sets of positive diopters and four sets of negative diopters, with varying strengths up to a 330p positive and 290n negative. According to Tom Murphy from ARRI, these filters allow filmmakers to “bake in” their image choice on the back of the glass, eliminating the need to put them in front of the matte box.
The filters are also small, which reduces the likelihood of them getting scratched, and they can be used on gimbals, drones, and Steadicam. ARRI is set to release films that showcase the different effects of the filters on the Signature Prime lens.
In addition to the impression filters, ARRI also displayed its Signature Zoom set, which pairs perfectly with the Signature Primes. The company also demonstrated how to match mini LF on its new camera, the Alexa 35.
At the BSC Expo 2023, ARRI also showcased its history of making cameras for over 100 years. The booth featured some of its old cameras, including a Canary from 1927 and an Ariflex 35 from 1937. The display is a testament to ARRI’s long-standing commitment to the film industry and its continuous innovation to improve the filmmaking process.

Hi I’m Tom Murphy from ARRI, we thought it’d be a good idea to show you what we were showing on the booth at the BSC Expo 2023.

The newest thing that we’re showing on the booth today is our new line of impression filters.
They’re for the signature Prime and they’re a magnetic filter that goes on the back.

So we have four sets of positive diopters and four sets of negative diopters.

They go up in different strengths, with the highest being a 330p positive and a 290n negative.

The best way to think about it is the 330p relates to a 3.3 positive diopter and the 290n relates to a 2.9 negative diopter.

We do have some films coming out over the next couple of weeks, we’ll be able to show you how these different diopters can affect the look of a signature Prime.

The beauty of these filters is that they go on the rear of the lens and then you’re baking in your image choice on the back of that glass.

All they do is just clip right on the back, they’re very very small so you’re less likely to get them scratched it means that you don’t have to put them in front of the map box.

And you can also fly them on gimbals drones and Steadicam.

We’re also showing a number of other things on the show we’ve also got our signature Zoom set so they pair perfectly with the signature primes and we’re also trying to show how you can  match mini LF on our new camera the Alexa 35.

On the booth today we’re are also showing that we’ve been making cameras for over 100 years, so we have some of our old cameras we’ve got a canary from 1927 and an ariflex 35 from 1937.
