The optics specialist Sirui has announced its membership in the L-Mount Alliance and has introduced a new lens to match, the Aurora 85mm f/1.4 autofocus lens. It was presented (in November 2024) - at that time with the mount options Sony E, Nikon Z and Fujifilm X. The presentation already took place in November 2023. ;)
Sirui Aurora 85mm f/1.4With a weight of 540g and dimensions of 80.3mm (D) x 101.7mm (L), the lens is compact; the tube is made of an aluminum alloy. Part of the optical design with 14 elements in 9 groups are one aspherical lens, 2 ED and 3 HRI lenses. This should minimize chromatic aberrations and stray light. ;) Sirui Aurora AF 85mm F1.4 lens The minimum focusing distance is 85cm. An AF lock button can be found on the lens, as well as a "Click ON/OFF" switch, so the aperture can apparently be unclicked (this feature is not explicitly stated). The aperture consists of 15 blades. The front lens is coated with a fluorine coating (anti-fouling), and the lens is also said to be dust and weather resistant. Its filter thread measures 67mm. L-Mount and the AllianceThe L-Mount Alliance was announced by Leica Camera AG, Panasonic and Sigma at Photokina 2018 and promotes the unified L-Mount system as a common standard for mirrorless system cameras and lenses. In 2021 Leitz and in 2023 Samyang, Astrodesign and Blackmagic joined the Alliance - Sirui is now the youngest member. The L-Mount competes with the proprietary standards of individual manufacturers such as Sony&s E-Mount, Canon&s RF-Mount, Nikon&s Z-Mount, Fujifilm&s X-Mount and Micro Four Thirds (MFT). ;) The L-Mount was introduced by Leica in 2015 and is now used by all manufacturers involved in the alliance as a non-proprietary lens mount for cameras. The universal compatibility and the diameter of 51.6 mm enables any combination of APS-C and full-frame cameras from different manufacturers with their lenses. No matter what the combination, virtually all quality and functional features of the different systems are fully retained. A major advantage of the L-Mount is its short flange focal distance of only 20 millimeters, which enables the construction of compact lenses and allows the adaptation of almost any other optical system.  more infos at bei store.sirui.comdeutsche Version dieser Seite: Sirui wird Mitglied der L-Mount Alliance und stellt erstes Objektiv vor |
