    Attacable lenses
    The lenses in the below can be attached to the MT-26EX-RT, in addition to the compatible lenses (as of December 2020).
    Note that when using these lenses for flash shooting, the image may be truncated due to mechanical vinetteing, or the exposure may change. Therefore, it is recommended to shoot test shots beforehand and apply flash exposure compensation or exposure compensation if necessary. Also note that vingnetting or exposure above may chnage depending on the shooting distance. When using a zoom lens, vingnetting or exposure above may chnage depending on the focal length.
