The Convex Reflex (コンベックスレフレックス) is a Japanese SLR camera taking daimeishi (6.5×9cm) plates or pack film, made by Sone Shunsuidō in the 1920s.

The camera has a box-shaped body with a rigid tapered front, a large viewing hood, a focusing helical and various controls on the photographer's right, certainly to wind, set and trip the focal plane shutter. It is not known if the camera has a revolving back or not.

The Convex Reflex was advertised in the November 1924 issue of Ars Camera as "soon coming to the market" (近々市場に出現する).[1] In a later advertisement, it was offered along with the Secrette 4.5×6cm detective camera and Apollo 6.5×9cm folder;[2] the price is given as ¥135 and the lens is described as a Complanar (コンプラナー) f/4.5, specially made by a French company in Paris for Tokyo Camera Works, the manufacturing branch of Sone Shunsuidō.
