These are compact, lightweight and reasonably priced super-telephoto RF lenses that guide users who experienced difficulty with super-telephoto shooting in the past, due to the impression that it was only for professionals. Thanks to a significant size reduction through the use of original DO lenses, high-image-quality expression and AF with an F11 aperture are now possible. Furthermore, these lenses are highly storable and maneuverable thanks to a collapsible structure.
