What is the DULENS APO Triassic Prime Series?
The DULENS APO Triassic Prime series is a cinema lens compatible with full-frame sensors. With a large image circle diameter of 46.5mm, it is also compatible with VistaVision-class large format sensors.
It achieves high resolution and excellent chromatic aberration correction thanks to its apochromatic design. Its close focus function allows for flexible use in close-up photography, including shooting close-ups of subjects and product photography. Its design also takes into consideration ease of use in film production, faithfully reproducing the texture and three-dimensionality of the subject, producing natural, deep images.
The set of five lenses includes focal lengths of 25mm, 35mm, 50mm, 90mm, and 120mm. It comes with a shock-resistant hard case, allowing you to safely protect the lenses while traveling.

Features
High optical performance and three-dimensional expression
Maintaining high resolution from the center to the edges of the image, these lenses produce incredible imagine quality. The design minimizes aberrations, beautifully reproducing the subject’s three-dimensionality and atmosphere. It maximizes the performance of the image sensor, achieving sharp, detailed depictions.
Apochromatic design and nano-coating for high-definition imaging
The apochromatic design reduces color bleeding and fringing, faithfully reproducing the subject’s colors. It achieves natural, clear color reproduction under any light source. Furthermore, the nano-level multi-layer coating effectively suppresses flare and ghosting, enabling high-contrast, sharp, and transparent images.
Combining close-up shooting with smooth operability
Equipped with a close-focus function, these lenses faithfully reproduces the texture and details of the subject, demonstrating excellent imaging power even in close-up shots. The focus ring features a stepless design with a smooth 270° rotation angle, allowing for precise focusing. Furthermore, it is equipped with a 0.8MOD gear that supports follow focus, providing high operability and precise control even in filmmaking environments.
Affinity and practicality with APO Mini Prime
While the brand’s “APO Mini Prime” series features soft tones with a vintage feel, the “APO Triassic Prime” series delivers more modern, high-contrast images. Both series are designed with the same bokeh and color characteristics, allowing for a consistent look even when used together. Furthermore, the follow focus gear position is the same, making it easy to switch lenses on location.
