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.
- Fn Button
With Fn custom function button, the function menu or shortcut operation can be quickly used to improve the efficiency of creation.
- Small and Lightweight
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.
- Quiet CNC Stepping Motor Integrated
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.
- F/2 Large Aperture
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.
- 9 Optical Lenses in 8 Groups with Nano-multilayer Coating
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.
- Aspheric Lens*1
Various aberrations can be compensated by an aspherical lens integrated.
- Low Dispersion Lens*1
Equipped with a low-dispersion glass lens, which can effectively suppress the dispersion problem caused by wide-angle.
- 7 Circular Aperture Blades
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.
- USB Firmware Upgrade
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.
- Metal Bayonet and Contacts
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.
