Sony E-mount Replacement
The Sony E-mount may be replaced with a taper mount ring and Canon EF lens adapter. The combination eliminates the possibility of reflections and vignetting by maximizing the entrance aperture for the full frame sensor. A Canon EF adapter also allows the insertion of 48mm or 52mm IDAS filters, making it possible to use IDAS filters even with wide-angle Canon compatible lenses. An additional benefit of the bayonet mount adapter is that it functions as a camera rotator for convenience when used with a telescope.
Nikon F-mount adapters are also an available option.
* Note: Canon EF and Nikon F-mount lenses are fully able to reach focus at infinity, but are
limited to manual focus and aperture control.
