Chinese lens maker 7Artisans has announced the AF 27mm F2.8 prime lens for APS-C cameras using the Sony E-Mount.
The 27mm focal length gives a fractionally wide-angle ∼41mm equivalent field of view, while the semi-fast F2.8 maximum aperture should give some control over depth-of-field and better low-light performance than a kit zoom.
The compact prime consists of six elements in five groups. It uses a stepper motor and internal focus design, which is potentially promising in terms of autofocus speed. Unusually for a modern lens, it makes no use of aspherical, ED or other special glass, and features just six aperture blades.
The 48mm (1.9″) long, 173g (5.0oz) lens features a USB 3.0 socket on its side, allowing firmware updates. It has a minimum focus distance of 0.3m (11.8″) and accepts 52mm threaded filters. It is available immediately at a recommended price of $129.
The Panasonic Lumix S5II launched the second generation of Panasonic’s full-frame mirrorless camera system and was the first Panasonic to feature phase detect autofocus. As our review reveals, it’s a heck of an all-around camera for both still and video shooters.
The latest Lumix puts a Four Thirds sensor in a full-frame body with boosted AF and a wealth of stills and video capabilities to create a Swiss Army Knife of a Micro Four Thirds camera.
The fourth camera in Leica’s SL series of full-frame mirrorless cameras sees the 60MP BSI sensor from the Q3 and M11 models arrive with a significant interface redesign.
The Fujifilm X100VI is the sixth iteration of Fujifilm’s classically-styled large sensor compact. A 40MP X-Trans sensor, in-body stabilization and 6.2K video are among the updates.
The Nikon Zf is a 24MP full-frame mirrorless camera with classic looks that brings significant improvements to Nikon’s mid-price cameras. We just shot a sample reel to get a better feel for its video features and have added our impressions to the review.
