At The Photography Show 2019 ePhotozine spotted this world’s first Pinhole Zoom Lens from Thingyfy. This 18-36mm has been show mounted on the Sony E-mount. There is yet no info about price and shipment date but I bet this lens will be available for other mounts too (like Fujifilm X and Micro Four Thirds).
Here you see the new pinhole zoom (in the center) with the other already existing Thingyfy pinhole prime lenses:
