A new Nikon lens patent is causing quite a stir in the photo world today, but it's not because of the lens itself. Instead, the patent has people excited because it describes a lens that is made for a curved full-frame sensor, possibly inside a mirrorless camera.
The latter bit is pure speculation—as Nikon Rumors points out, "the patent does not provide sufficient technical information to determine if this is a mirrorless or a DSLR lens," especially since Nikon has patented curved sensors in the past—but the 35mm F2.0 lens described is definitely made to work with a full-frame curved sensor.
The Sony FE 16-35mm F2.8 GM provides the constant F2.8 wide-angle zoom that has been so conspicuously absent from the company's full-frame lineup until now. A fast wide-angle zoom is a common element in many photojournalists' camera bags, as well as being a favorite of landscape shooters and will sit alongside the 24-70mm F2.8 and 70-200mm F2.8 GM lenses in a classic trinity of fast zooms.
In common with other G Master lenses, the company says it's designed to achieve good performance even by 50 line pairs / mm standards wide-open and has been designed with bokeh as a consideration through the development process. It also includes extensive internal and external sealing to provide water and weather resistance.
Canon has presented a reduced 35mm F2.8 IS STM large scale focal point for yield sensor DSLRs. Comparable to the EF-M 28mm F3.5 Macro focal point presented a year back, the 35mm F2.8 has an implicit LED ring light.
The focal point, which is identical to 56mm when mounted on product body, has a base concentration separation of only 3 cm (1.2 in.). It uses Canon's 'Hybrid' IS framework, with up to four stops of shake diminishment. Ordinance says that the lead-screw-sort STM engine takes into account calm AF operation, which is perfect for video catch. The focal point has seven adjusted gap cutting edges and in addition a glass-shaped aspherical element.
