FAQs
Does the Dulens APO Triassic Prime lens cover full-frame sensors?
Yes, the lens covers up to full-frame sensors with a 46.5mm image circle, ensuring it can be used across a wide range of modern cinema cameras. It delivers consistent coverage without vignetting across the intended format.
How is this lens different from the APO Mini Prime series?
The Triassic Prime lenses complement rather than replace the APO Mini Primes. While the Minis offer a different set of focal lengths, the Triassic line provides close-focus performance, apochromatic correction, and expanded coverage with no overlap.
What is the benefit of the apochromatic design?
The apochromatic (APO) and floating element design minimises chromatic aberration, controlling colour fringing and distortion across the frame. This results in sharper, more accurate images, especially noticeable in close-up focus and wide-open shooting.
Is the lens suitable for use with cine accessories?
Yes, the consistent 80mm front diameter and 72mm filter thread make it compatible with standard matte boxes, filters, and accessories. The cine-standard 0.8 MOD gears and 270° focus rotation also make it well-suited for follow focus systems.

The Buy Now Pay Later option comprises a 36 month loan following a six month deferral period.
During the six-month deferral period, it is possible to pay off the loan, either by way of a lump sum or in smaller amounts. If the loan is partially repaid within six months, the remaining interest will be adjusted to reflect the new balance. If the loan is fully repaid within the six-month deferral period, then no interest is payable, however, a £29 early settlement fee is payable in respect of repayments within these six months.
Following the six-month deferral period, Novuna Personal Finance will initiate a monthly direct debit payment for the remaining duration of the loan. Interest will be charged at a rate of 18.9% APR (representative) on outstanding balances (backdated to the first date of the loan). Novuna Personal Finance will send a reminder letter approximately one month before the six-month deferral period is due to elapse.
