DZOFilm has announced the Marlin 1.6x Expander that adapts Super35 lenses to larger sensors. It promises to not only extend the effective focal length of those lenses but also the image circle itself.
The DZOFilm Marlin 1.6x can convert Super35 to cover both full-frame and Vista Vision cameras like the ARRI ALEXA LF/ Mini LF, Sony VENICE 1 and 2, and RED V-RAPTOR.
Constructed with what DZOFilm says are high-resolution optics, the Marlin 1.6x Expander also enlarges the image circle and focal length without changing the field of view, adding a vignette, or causing appreciable degradation of image quality. The loss of light, however, is about 1.5 stops.
The expander has a detachable supporting base and stainless steel mount and weighs just under 25 ounces (seven kilograms) and the whole device is 109mm in length. DXOFilm states that the design also uses unique mounting rings so there is no need for shims or mount replacements to make the expander fit.
The distance from the flange plane of a PL mount lens, for example, to the rear is less than 19.64mm. DZOFilm also offers an adapter clearance check tool, which can be downloaded from the DZOFilm website, to calibrate the back focus and ascertain the lens compatibility of other lenses outside of the Pictor Zoom series, which the expander is optimized for.
The company has created a series of videos that outline the procedure after the adjustment tool has been printed and prepared. Users just need to scan the QR code, which will direct them to the page that has the tutorials. There are three tutorials that cover DZOFilm’s line of lenses including Pictor Zoom, Cata Zoom, and LingLung, but the company implies that the principles can be used on third-party lenses as well.
Users can also print the PL Mount Clearance Check template to verify there is enough clearance to add the Expander Adapter to the required lens. Just cut out the mounting template and then transfer it to cardboard or other more sturdy material before verifying fit.
The price of the DZOFilm Marlin 1.6x Expander varies depending on the mount, but the base price is $1159 with versions covering PL-E, PL-RF, and PL-L. There is also a PL-LPL and PL-PL version for $1699. Shipping is expected in early July.
