Schneider-Kreuznach launches the ISCORAMA 54 adapter "new and modern". It allows 1.5x anamorphic shooting with a "normal" lens when screwed on as an attachment. The original, released in the late 1970s, enjoyed a revival when DSLR filmmakers discovered it for themselves, so much so that in 2010 there was even a brief price explosion.
The new adapter will appear in an ISCO4all set together with three "ISCOspherical" Mini Cine Primes from DuLens in the focal lengths 43mm/T2.4, 58mm/T2.4, 85mm/T2.4. DuLens is a small lens manufacturer from Hong Kong and apparently contributes special versions of its extremely compact full-frame cine lenses (length 83mm, diameter 81.6mm) for the set. They are equipped with PL mount and cover an image circle of 46.5mm. According to the manufacturer, the lenses follow a classic optical design and offer a vintage look, also due to a rather simple coating. The aperture consists of 11 blades. More info on the (original) DuLens lenses can be found in this Facebook group.
To what extent the new ISCORAMA 54 adapter differs from the old original is not exactly clear from the current data. Apparently the same focusing system is used as before (patented ISCO single focus system), so that during filming the focus is controlled via the adapter, while the optics behind it are set to infinity. The minimum focusing distance is 1.4 meters.
The ISCO4all set consisting of the ISCORAMA 54 CU - 1.5x anamorphic adapter and the three cine optics is scheduled to be available in January 2022, but only at specially selected rentals.
