Expand the focal length of your S35 format PL-mount lens when using it on a full-frame sensor camera with this S35XVV
Large-Format 1.66x Expander Mount Adapter for S35 Lenses from IBE OPTICS. The expander supports high-resolution imagery while scaling the image through an $35 PL mount lens on large-format sensors with up to a 46.5mm image circle. It is designed to magnify your focal length by 1.66x.

The extender features minimal optical degradation while expanding the focal length and decreasing the image brightness by 1.46 stops. To create an optimized optical design for modern lenses and digital cameras, the maximum input is T2.0. The S35XVV is designed to mount a PL lens on any digital cinema camera with a native PL mount, and the UMS lens mount system allows you to interchange the camera mount with optional Canon EF, Sony E, MFT, or other available mounts to fit a wide range of cameras. Its durable design incorporates stainless steel PL mounts and an anodized aluminum body.

The FE 2x Teleconverter increases the lens’s magnification by 2x for a narrower field of view. The dedicated design maintains full communication between the lens and E-mount mirrorless cameras, including auto-exposure metering, autofocus, and Optical SteadyShot image stabilization. Additionally, this teleconverter also features a dust- and moisture-resistant construction, matching the lens, to benefit working in harsh environmental conditions.

The FE 1.4x Teleconverter increases the lens’s magnification by 1.4x for a narrower field of view. The dedicated design maintains full communication between the lens and E-mount mirrorless cameras, including auto-exposure metering, autofocus, and Optical SteadyShot image stabilization. Additionally, this teleconverter also features a dust- and moisture-resistant construction, matching the lens, to benefit working in harsh environmental conditions.

The Extender EF 2X IlI from Canon is designed for select Canon EF mount L-series telephoto lenses. It increases the focal length of a lens by a factor of 2x while still delivering superb image quality. To ensure the best possible image quality in all shooting conditions, it combines redesigned optics, improved data communication between lens and camera and enhanced environmental protection. It is ideal for photojournalists and wildlife, nature and sports photographers who need to get close to distant and challenging subjects and it reduces the need to carry heavy telephoto lenses.
