Used to adjust the focal point of the Z-Finder Pro and Jr. viewfinders, Zacuto's Z-Finder Extender Frames are designed primarily for farsighted shooters and those who require reading glasses. The frames snap onto the Z-Finder and can be stacked as needed, until focus is achieved. In the case of the Pro series viewfinders, the frames function as further extensions to the diopter's dial-in focus, while for the Z-Finder Jr. these are required to make any adjustment to the -2.75 focal point.
Note: Extender frames will also work on V2 models purchased after January 25, 2010. If you ordered a V2 before January 25th, please contact firstname.lastname@example.org
