The Chinese company Yongnuo has released an ultra-wide-angle lens with an autofocus system – Yongnuo YN 11mm F/1.8S DA DSM WL for Sony cameras with APS-C matrices. Previously, this optics was released for Nikon Z. Moreover, the lens has a built-in remote focusing system using a wireless remote control, which has a frequency of 2.4 GHz. In the future, the lens will also be available for Fujifilm X cameras.

The Yongnuo YN 11mm F/1.8S DA DSM WL lens has an available aperture range of F/1.8-F/16. The diaphragm design is seven-blade.

The optical design of the lens consists of 10 elements in 9 groups. Including three low dispersion elements, two extra-low dispersion elements, three high refractive index elements and two aspherical lenses. The manufacturing company has published a drawing of the optical design of the Yongnuo YN 11mm F/1.8S DA DSM WL lens:

The minimum focusing distance available when shooting with the new lens from Yongnuo is 0.15 m, and the maximum magnification is 0.15x. MTF graphs at different aperture values ​​look like this:


The lens filter diameter is 58mm, and its dimensions are 66x69mm. The lens weighs 260 grams. There are various switches on the lens body: aperture operating modes (with and without clicks), a programmable button, as well as the aperture adjustment ring itself.

There is also a USB-C port for updating the lens firmware.

The optics are a fairly good option for shooting with an ultra-wide viewing angle and at the same time with a high aperture ratio – F/1.8.

It was previously reported that the Yongnuo YN 12-35mm F/2.8-4 autofocus lens for M4/3 went on sale. The lens provides a standard set of focal lengths, equivalent to 24-70mm (at full frame). The manufacturer reported that the optical design of the new Yongnuo YN 12-35mm F/2.8-4 for M4/3 uses aspherical lenses, elements with low dispersion and high refractive index. All of them allow you to control aberrations and obtain a sharp image.
