They look pretty OK. If they have decent film backs (i.e. flatness), then they could be a great option. I'd like to see a 612 version. OTOH, I don't want to start to regret selling my 4x5 lenses (three Fujinon Copal 0's, and a JML Optical Super Wide), about a dozen years ago. I mostly used them on a 4x5 Shen Hao, with a 612 back.
I went thru his site, Utube videos, and Instagram account too see if he was real. I have seen him online in earler vodeos learning about how to make cameras and with his fathers help he seems to be there now as far as making cameras.
His loading of 120 film is very different than others and he has knobs on the bottm of the camera to keep the film flat. The 120 camera uses Mamiya Press 23 lenses which come with a focusing mount. But it wasn’t clear to me how that setup ends up being in focus.
And his 35mm pano body is impressive with film transport, numbering system, and laser to give you focus setting.
