MTF Services Ltd PL to Sony E Lens Mount Adapter

We are not aware of the exact mechanics behind how this adapter is constructed, but it does indeed offer a 1.1x magnification.

The MTF Services Ltd PL to Sony E Lens Mount Adapter (B&H # MTMTPLSEM) is not for the FX3. It works with the Sony NEX-3, the NEX-5, the NEX-VG10, and the NEX-FS100 cameras. However, the following Metabones adapter would work with the Sony FX3: the Metabones ARRI PL Lens to Sony E-mount Camera T Adapter (Black), B&H # MEMBPLEBT2.

On metal bodied cameras with integral PL mounts prime lenses weighing up to 4 lbs, such as each of the Sony Cine Alta lenses, are fine in low stress situations and have no need of particular support. In stress situations such as high speed car stunts or roller coasters, a lens support would be highly recommended. Not only there an issue of the lens mount being broken but there would be the more insidious issue of the back focus depth being altered and you getting soft images. Light weight cameras with an E mount or EF mounts are not designed for large heavy PL mount lenses, particularly zooms. In these cases, we would recommend lens support as healthy and cheap insurance.
