Get closer, get bigger. 800mm maximum focal length long telephoto mirror lens + extender set. This long telephoto set includes the SZX 400mm F8 Reflex MF mirror lens, which achieves a focal length of 400mm in a compact body, and the SZ 2X EXTENDER for T-mount extender, which doubles the focal length. [Can be used in two ways: 400mm or 800mm] Simply attach and detach the "SZ 2X EXTENDER for T-mount" to change the lens to have a focal length of 400mm or 800mm, so you can use it depending on the scene, such as 800mm for photographing the moon's surface and 400mm for photographing birds on the ground. [Reflective optical system that produces a distinctive "ring bokeh"] The lens uses a distinctive reflective optical system that produces a "ring bokeh" effect, making the blurred areas of point light sources appear as if they have a hole in the center, resulting in a unique and fantastical depiction. [Convert to a different mount with the T-Mount Adapter II] Both the lens body and the extender use a T-Mount. They are attached to the camera using a "T-Mount Adapter." If you have cameras with multiple mounts, you can easily switch between them by purchasing a "T-Mount Adapter." (The lens does not have electronic contacts.)
