With current lens technology it’s just very difficult. Sure, you can do it in a “Pimaxian” way (or even call it an “VRgineers” way if you want, cause the XTAL lenses also just aren’t really good) and release something that “works” (kinda LOL) but most companies feel that the optics should be good and that’s just very difficult for high FoV.
Pancake was a nice improvement but we need a new breakthrough.
I posted a long tech video on the subject last week, it really opened my eyes, never realised that it’s just a physics thing. Without such breakthrough it seems not likely that the big companies will release anything 140+ in the coming years.
With current technology it’s just not possible to make 140 hFoV lenses, for small pixel size, that are sharp all over the lens.
