It's been a long time since Hejnar Photo has introduced the D027 Arca Style Quick Release plate. It was originally introduced in 2014 to cover the fixed lens Finepix models designated Dedicated D027 QR Plate for Fuji X100/S.
What is interesting though, is that after thorough testing it is declared directly compatible with the newer Fujifilm X-T20 which seems to share the same smaller base footprint.
