because customer support is a big hassle. sony is one of the few sensor manufacturers left and they would rather only deal with manufacturers than hobbyists doing god-knows-what. you can get them, though. arducam makes a cute little accessory board and sells kits with sensors pre-installed, and will also quote the more uncommon sensors for you if you send an email. https://www.arducam.com/docs/camera-breakout-board/ https://www.arducam.com/docs/camera-breakout-board/ you can also find quotes from other suppliers. sony does full-frame and medium format sensors wholesale, and they’re available through distributors. https://www.sony-semicon.co.jp/e/products/IS/camera/product.html https://www.sony-semicon.co.jp/e/products/IS/camera/product.... but of course, in most cases, these manufacturers would prefer that you buy a finished camera. there is really not much you can do with a bare sensor that isn’t easier with a consumer product, especially if you want to put a lens on it.
