William Optics 4 Extension for Flat GT

William Optics 4 Extension Tube for Flat GT: Custom backfocus for your Flat GT train

This William Optics extension tube brings your camera train to the correct length when working with the Flat GT and lacking backfocus. With 67 mm (2.6 inches) of optical length and M92 threads on both sides, everything is fully screwed together, without play or tilt.

In photography, a geared tripod head is the only route to repeatable sharpness: your camera stays level, your framing holds firm, and corner stars remain round.
