Canon has introduced a groundbreaking new ultra-wide angle fisheye zoom lens, the RF 7-14mm f/2.8-3.5L Fisheye STM. This new lens is the primary of its variety for the Canon RF mount and picks up the mantle from the legendary Canon EF 8-15mm f/4L USM.
The Canon RF 7-14mm f/2.8-3.5L STM is the world’s widest angle zoom lens with a 190° subject of view, which means it may well see behind itself. The favored EF 8-15mm f/4L USM, which was a pioneering lens at its launch in 2010, delivers a 180° subject of view. As if it wanted one other feather in its cap of technical achievements, the lens can also be Canon’s brightest ultra-wide angle lens ever made.
With a good wider subject of view, quicker aperture, and fashionable optical expertise, Canon believes its new fisheye zoom will probably be an distinctive selection for dynamic motion, sports activities, and panorama pictures and videography.
When used at 7mm, the lens delivers a 190° subject of view and a round fisheye image. Because the consumer zooms, the lens transforms right into a diagonal 180° fisheye zoom. As for the variable aperture, the lens maintains its f/2.8 aperture solely at 7mm. At 8mm, the lens slows to f/3.2, then reaches its slowest most aperture of f/3.5 at 11mm.
As anticipated, the lens has a complicated optical design. It options 16 parts organized throughout 11 teams, together with 5 ultra-low dispersion (UD) parts and a pair of aspherical glass parts. It options Canon’s Tremendous Spectra Coating (SSC), Air Sphere Coating (ASC), and fluorine coating on the entrance ingredient.
Though tough to quantify, the brand new fisheye zoom lens additionally guarantees extra real looking rendering than the EF 8-15mm f/4L lens. The brand new zoom lens affords equidistant projection, which means that the picture subject initiatives evenly to the middle, and the relative dimension of topics in numerous parts of the body and at varied distances from the lens is precisely rendered. The older EF 8-15mm lens, then again, initiatives barely bigger within the heart. This may occasionally not matter a lot in most functions, nevertheless it does profit efficiency in VR workflows.
The interior zoom lens has a drop-in filter slot at its rear, which accepts the identical drop-in filters as Canon’s Mount Adapter EF-EOS R. A transparent drop-in filter ships with the lens and is functionally similar to Canon’s current clear drop-in filter, although it lacks textual content on its edge. The drop-in filter is a part of the lens’s optical path, so one ought to at all times be put in when taking pictures. Because of this drop-in filter holder, photographers and videographers can make the most of round polarizing and variable impartial density (ND) filters on the fisheye zoom lens. Given the form of the lens, it’s apparent why a entrance screw-in filter isn’t an choice.
From a design perspective, the brand new RF 7-14mm f/2.8-3.5L Fisheye STM is kind of related in dimension to the EF 8-15mm f/4L Fisheye. The brand new lens is roughly 4.3 inches (109.4 millimeters) lengthy, much like the size of the EF 8-15mm f/4L Fisheye when used with a Canon EF-RF adapter. The lens has a max diameter of three inches (76.5 millimeters) and weighs 16.8 ounces (476 grams), lower than the EF 8-15mm by over two ounces (64 grams).
The extremely wide-angle fisheye zoom lens options Canon’s leadscrew-type STM focusing system, promising fast, quiet, and correct focusing for each pictures and movies. The lens can focus as shut as 5.9 inches (0.15 meters), leading to a max magnification of 0.35x within the heart of the picture at 14mm. Canon notes that the lens has minimal focus respiration of simply 0.4% at huge and 1.5% at tele.
