Yongnuo announced a new YN35mm f/2S DF DSM autofocus lens for Sony E-Mount. Additional information (in the US Yongnuo lenses are sold at Adorama, B&H, and Amazon):
YN35mm F2S DF DSM is a small, lightweight, and universal F/2 large-aperture full-frame lens suitable for landscape, night scenes, street photography, food, and other photography subjects.
With Fn custom function button, the function menu or shortcut operation can be quickly used to improve the efficiency of creation.
The maximum diameter and length of the lens is about 67*72mm and the net weight is only about 295g. The lightweight design is portable for daily use and long-term hand-held shooting and video recording.
Compared with traditional DC motors, digital stepping motors (DSM) have a fast start-stop response, high focusing accuracy, and quieter focusing actions, which are suitable for photo shooting and video recording.
With an F/2 large aperture, it's easy to get a soft blur effect. You can also use low sensitivity and higher shutter to shoot in a low light environment.
The structure which is composed of 9 elements/ 8 groups with nano-multilayer coating effectively improves the light transmittance and suppresses back-light ghosts and glare.
Various aberrations can be compensated by an aspherical lens integrated.
Equipped with a low-dispersion glass lens, which can effectively suppress the dispersion problem caused by wide-angle.
The lens is designed with 7 circular aperture blades. It can shoot circular diffuse spots. It can also take pictures with 14-star effects if the aperture is appropriately reduced.
With a USB Type-C interface on the lens, you can download the latest firmware for an upgrade to keep the lens at its best performance.
The use of high-precision metal bayonet and gold-plated contacts effectively improves signal conductivity and corrosion resistance. At the same time, it allows the camera and lens to maintain reliable communication and realizes functions such as auto-focus, aperture control, and EXIF information transmission.
