DZOFILM Announces Octopus II Multi-Mount Lens Adapter & Marlin 1.4x Extender

Press text:

DZOFILM has announced the launch of the Octopus II Adapter and Marlin 1.4x Extender, providing with greater flexibility, compatibility, and efficiency across a wide range of filmmaking applications, from short-form bloggers, content creators, livestreamers and YouTubers to independent filmmakers, commercial media and advertising, and professional DOPs.

Octopus II: 2nd Generation Multi-Mount Lens Adapter
The new Octopus II is a highly versatile multi-mount lens adapter that supports E, Z, L, and RF mount lenses, as well as Super35, full-frame, and medium-format sensors. With 7.12% more internal space, it offers improved compatibility with DZOFILM’s Arles, Arcana, Vespid, Catta, Pictor, Gnosis, and other professional cinema lenses.

The second-generation design is up to 49% lighter, weighing as little as 190g (depending on mount). Its strong aluminum body is paired with a stainless-steel mount that is rated for more than 100,000 mounting cycles with 0.01mm precision, ensuring long-term reliability and durability.

The redesigned ergonomic handle features directional guides that make lens changes easier, particularly when working with handheld or fully rigged camera setups. A detachable 1/4″ threaded base allows the center of gravity to be shifted onto the adapter, reducing stress on the camera’s native mount. In addition, the factory pre-set flange focal distance eliminates the need for calibration while ensuring accurate infinity focus.

Marlin 1.4x Extender with Integrated Back-Focus Adjustment
The new Marlin 1.4x Extender increases effective focal length by 1.4x while maintaining light loss below one stop, enabling lenses designed for Super35 to cover full-frame sensors.

The extender incorporates premium high-refractive-index SR optical elements, large-diameter aspherical lenses, and an internally flocked design that effectively minimizes stray light. Chromatic aberration is tightly controlled, helping preserve the original character of the lens. Integrated back-focus adjustment eliminates the need for operators to detach the lens or use shims during setup and fine-tuning.

Manufactured with stainless-steel mounts on both sides, the Marlin 1.4x Extender is engineered for long-term reliability and durability. Precision machining further helps prevent binding during mounting and operation.

Matt Granger Best 70–200mm f/2.8 Lens — Canon | Nikon | Sony | Sigma | Leica

In this video, photographer Matt Granger conducts a shootout between five professional 70-200mm f/2.8 lenses from top manufacturers. Tested on their respective high-resolution camera bodies in Hong Kong, the lenses are evaluated on handling, build quality, autofocus performance, image stabilization, and overall image quality.

The Five Contenders

Canon RF 70-200mm f/2.8L IS USM Z (tested on Canon R5 Mark II)
Nikon NIKKOR Z 70-200mm f/2.8 VR S II (tested on Nikon Z8)
Sony FE 70-200mm F2.8 GM OSS II (tested on Sony A7R V)
Sigma 70-200mm f/2.8 DG DN OS Sports (tested on Leica SL3)
Leica Vario-Elmarit-SL 70-200mm f/2.8 ASPH(tested on Leica SL3)

Matt concludes that if you are using a Sony, Nikon, or Canon system, their respective 70-200mm lenses are absolute top-tier choices that will not disappoint. The Sony takes a slight edge for its incredibly lightweight and ergonomic design.
Conversely, the Leica acts more like a luxury item—it looks and feels premium but is too heavy and slow for demanding professional workflows. The Sigma, while optically sound, struggled massively with autofocus tracking, making it hard to recommend in this highly competitive class.
