08 Sep

Chinese lens manufacturer Jakumei Optics has announced (translated) the release of the Dulens APO 85mm F2 manual lens for Canon EF- and Nikon F-mount camera systems.

According to the manufacturer, the lens’ apochromatic (APO) design is inspired by ‘Sonnar-style’ lenses, the first of which was created by Dr. Ludwig Bertele in 1929.

The lens is constructed of seven elements in six groups, including two extra-low dispersion elements and one high-refractive index lens. Other features include an aperture range of F2-F16, a nine-blade aperture diaphragm, a 90cm (3ft) minimum focusing distance and a 55mm front filter thread.

The lens is available in black, grey and silver, and is available to purchase on the Shoten Kobo website (translated) for approximately $ 735 (76,950 JPY).

DULENS APO 85mm F2 is a new manual prime lens for Canon EF, Nikon F camera systems

25 Sep

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:

$ (document).ready(function() { SampleGalleryV2({“containerId”:”embeddedSampleGallery_3582120122″,”galleryId”:”3582120122″,”isEmbeddedWidget”:true,”selectedImageIndex”:0,”isMobile”:false}) });

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.
