Unlock new creative options with the CHIOPT 1.7X Lens Extender, a precision-built PL-to-PL mount optical adapter that enhances both focal length and image coverage. Designed for filmmakers working with ARRI PL-mount gear, this extender multiplies your lens's focal length by 1.7x — perfect for getting closer to your subject without sacrificing optical clarity. In addition to focal length extension, it also expands your lens's image circle. This means Super35-format PL lenses can now cover full-frame sensors, breathing new life into legacy glass. Unlike many other extenders that sacrifice image sharpness, the CHIOPT 1.7X preserves excellent resolution at the center and minimizes degradation at the edges. Compatible with PL-mount lenses with rear optics shorter than 12.3mm (check before use), this extender weighs just 379g and fits snugly into your cine setup. Whether you're adding telephoto reach or adapting lenses for full-frame systems, the CHIOPT 1.7X Extender is an essential tool for professional cinematographers.
