ARRI launches eight Impression V Filters to change the bokeh of its Signature Prime and Zoom lenses
ARRI has announced a line of Impression Filters for its lenses. The new range of products includes eight Impression V Filters that give a vintage feel to Signature Prime and Zoom lenses. They are four negative and four positive diopter filters, and they increment the focus characteristics of the image.
Impression V Filters are not made in the usual way. Diopters are traditionally positioned in front of a lens. The four positive Impression V Filters are named IV 070P, IV 140P, IV 230P, and IV 330P, while the four negative filters are IV 050N, IV 100N, IV 200N, and IV 290N. In both cases, the increasing numbers signify a stronger diopter effect. Impression V Filters are designed to be used at T1.8, where the effect is strongest and lens scales remain accurate. Positive filters attach directly to the rear of each Signature lens, whereas the negative filters require a shim to be added to the back of the lens first. There is a 2 mm shim for shooting at T1.8, and a 1.85 mm shim to act as a base for the additional shimming required to shoot with Signature Zooms, or at higher stops with Signature Primes.
The company states that Impression V Filters work with its latest cameras: the ALEXA 35, ALEXA Mini LF, ALEXA LF, and ALEXA 65. The filters are sold in a kit that contains all eight of them, as well as a shim set, an adjustable torque screwdriver for adding shims, and inscribable Velcro tabs for labeling filtered lenses on set, all packaged in a specially designed aluminum flight case. For customers who don’t need a full kit each of the eight filter types can be purchased in a separate three-filter set.
