The Toyo-View VX Ultra-Flex Bellows is the standard-supplied bellows with 4 x 5" VX125 cameras, and offers both ample flex for short focal length lenses with extreme movements as well as maximum extension for lenses of approximately ~240mm at close-up distances (or 300mm lenses at infinity).
The shortest recommended lens for this bellows is 45mm with recessed lensboards, and 58mm with normal lensboards.
Bellows wear out with time and use, and this is offered as a replacement part.
