Fast and efficient autofocus with DLSM Technology

DLSM (Dual Linear Sonic Motor) works with ultrasonic vibrations, which cannot be heard by human ears, to successfully give a silent autofocus performance. The accurate high frequency signals, controlled with Samyang’s own protocols, precisely operate the DLSM. Specialists in optics, mechanical engineering, and electronics, have researched cooperatively to give these powerful results for a short telephoto lens. The introduction of DLSM technology on an 85mm lens means you can comfortably and silently capture the subjects you want, with quick efficiency.
