Is the APO design worth it over a standard prime?

The apochromatic elements target in-focus and out-of-focus color fringing, which shows most on high-contrast edges wide open. If you shoot backlit or high-contrast scenes at T2.6, it is a real advantage. Stopped down, the difference from a good standard prime narrows.

Does it cover a full frame sensor?

Yes, Dulens rates it for full frame coverage. Check clearance on very wide sensors and any adapter or speed booster you add, since those can change the image circle.

Can I change the mount?

Yes, the lens uses interchangeable mounts, so it can move between PL and other systems. Confirm the specific mount kit is available for your camera before you rely on it.

How does it compare with the 21mm in faster cine sets?

It is a stop slower than T1.5 wides, so it needs more light or a higher ISO. In return it is smaller and gives a softer, more vintage image with rainbow flare rather than a clean modern look.

Is the flare a problem?

The rainbow flare is part of the look and can be used creatively. If you need flare-free coverage, flag the lens or choose a modern coated prime instead.

Our take on the APO Mini Prime 21mm T2.6 Lens (Silver, Arri PL)

The Dulens APO Mini Prime 21mm T2.6 is a wide-angle cine lens in Arri PL mount with an apochromatic optical design aimed at suppressing color fringing, even wide open. It covers full frame, has corrected geometric distortion, interchangeable mounts and a deliberately vintage rendering with rainbow flare. It suits owner-operators and small crews who want a compact wide with a filmic look rather than clinical sharpness. Against modern cine primes it trades absolute resolution and speed for character and a lower entry point, and it is a stop slower than the common T1.5 wide primes.
