The Hubble Space Telescope, HST, has four cameras - three wide field (WF) cameras and one planetary camera (PC). Most images from HST is assembled from images from these four cameras, of which the PC is in the top right hand corner - that's why images from Hubble has a staggered appearance in that section of the image. Each camera uses a CCD that renders 800x800 pixels.

A field camera is a view camera, with limited movements, which can be folded up into a small size for transport (in the field, get it!) Toyo is a Japanese manufacturer of field cameras. A "Toyo Rosewood Field Camera" is a field camera, manufactured by Toyo and made from rosewood. This is not an expensive camera as field cameras go, but may be worth several hundred dollars on the used market.
