Dulens APO Mini 21mm T2.6 Overview

Full-Frame Vintage Look
Create an expressive, softer look for your cine-style capture with this black Canon EF-mount APO Mini 21mm T2.6 Prime Lens from Dulens. Each lens in the APO Mini series covers up to full-frame sensors and features a special coating that smooths out skin tones and adds halation for a classic vintage feel. Shoot with the aperture wide open to create a notable rainbow flare, or stop down to minimize any flaring. The APO Mini Prime lens focus is sharp but not rigidly so, producing a gentler look. Its 21mm focal length helps capture a wider angle of view.
Apochromatic Design
The APO Mini series uses an apochromatic (APO) design to aid in eliminating the effects of in-focus and out-of-focus color fringing when working with a fully open aperture. This design also ensures that the picture's color remains pure and natural, which is especially important when working with scenes that require the subject to have precise edges, like blue and green screen keying.
Compact Form
With an average weight of just over 1 lb, the APO Mini primes are some of the lightest, most compact cine-style lenses available, making them ideal for gimbal, handheld, and drone capture. Consistent design elements like an 80mm front outside diameter, a 72mm filter thread, and a compact form make it easy to switch between lenses when using matte boxes and other lens accessories.
Interchangeable EF/PL Lens Mount
This lens can be used with other systems via separately available adapters/mounts, enabling you to use it with a wide array of cine-style and mirrorless cameras.

Dulens APO Mini 21mm T2.6 Reviews

Not compatible with DSMC2 RED

By Aidan
Rated 2 out of 5

This lens isn’t compatible with DSMC2 Red cameras. The rear lens element protrudes too far past the ef mount. I have the other lenses in the set and they all work and look great.
