・SONY FE 400mm F2.8 GM OSS (SEL400F28GM) lens ・SONY FE 600mm F4 GM OSS (SEL600F40GM) lens This is an Arca-Swiss compatible lens foot with a QD socket for the above lenses. I am selling it due to a system change. The exterior shows some signs of use, but is in good condition without any noticeable scratches. Accessories include a drop prevention screw (already attached to the main unit) and a hex wrench. The hex wrench for attaching and detaching the lens foot is also included, although it is not shown in the image. Thank you for your interest.
