About Supersonic Wave Drive Technology Olympus-proprietary SWD technology has enabled an ultra-fast, whisper-quiet, high-precision AF system. Two compact, high-powered Supersonic Wave Drive devices power autofocus at an ultra-high speed by exciting unique elliptical oscillations, while an ultra-compact 5.3mm x 4.3mm optical encoder detects and controls the lens drive position using direct rotation detection without reduction gear. This enables it to achieve a level of precision that’s accurate to 5 microns (5/1000 mm). When used in combination with the new E-3, which offers improved AF computation and lens-body communication rates, the SWD motors provide the fastest focusing speed of approximately 170 ms (0.17 seconds).
