The Dulens APO Cambrian Prime 55mm T2.0 provides expansive medium format coverage for large sensors such as the ARRI Alexa 65 and Fujifilm GFX Eterna, serving as a versatile wide-standard prime. On these larger canvases, the 55mm offers a field of view reminiscent of a 40mm on full frame formats, providing an immersive perspective that maintains a naturalistic rendering of subjects while capturing a significant portion of their environment. Its 0.36 meter close focus capability and fast T2.0 aperture allow for intimate, detail oriented cinematography that benefits from the unique depth and characteristic fall off inherent to medium format optics. The 55mm delivers a balanced, three dimensional image that is well suited for high resolution productions requiring both technical precision and a distinctive aesthetic personality.
The APO Cambrian Prime series is defined by an apochromatic design that ensures edge to edge sharpness and minimal chromatic aberration across high resolution sensors. To preserve a natural and organic aesthetic, Dulens has avoided the use of aspherical elements in this line, resulting in smooth, artifact free bokeh without the common onion ring textures found in modern glass. Each lens in the set features a proprietary V+ coating to balance modern micro contrast with gentle highlight roll off and subtle vintage flare. For streamlined efficiency on professional sets, the series shares consistent gear positions for focus and iris, a 270 degree focus rotation, and a uniform 80mm front diameter. Most focal lengths in the series, including the 55mm, feature a 72mm filter thread to accommodate screw in filters for compact configurations. These lenses come equipped with a PL mount, while interchangeable mounts in Canon EF and Fuji GFX can be purchased separately.
