A new Chinese optics manufacturer has released the DULENS APO 85mm F2, a manual medium telephoto prime for Canon EF and Nikon F camera systems.

Although not much is known about DULENS itself, Newsshooter is reporting it’s been told that the optical engineer behind DULENS is the same who helped bring the NiSI F3 and MAVO prime lenses to life.

The lens, which is inspired by the Zeiss Sonnar series, is constructed of seven elements in six groups and includes an Apochromatic element to reduce chromatic aberration. It measures 5.8cm (2.28in) long, weighs 350g (12.35oz), features a 29-degree field-of-view, uses a 55mm front filter thread and has a minimum focusing distance of 90cm (35.43in).

Below are a number of high-resolution sample images shared on the product listing. These were shot with the lens on a Lumix S1 using an EF adapter:

The lens is available to pre-order in black and silver varieties for Canon EF and Nikon F camera systems. It’s currently listed for ¥2999 (approximately $420) on Chinese retailer Taobao, but Newsshooter says the company intends to release the lens in the United States and Europe market for $599.

We have contacted the retailer for more information on the lens and availability and will update this article if and when we receive a response.
