ZWO Adapter for Sony lenses: manual Sony glass on your ASI camera
With this M42 adapter, you can attach manual Sony DSLR and E-mount lenses to ZWO cameras with smaller sensor formats, such as the ASI294, ASI183, ASI174, ASI432, and ASI585. Useful for wide-angle imaging, all-sky work, and widefield astrophotography with existing Sony glass.
The adapter connects via the standard M42 screw thread and provides a light-tight connection with 34 mm of backfocus. Only fully manual lenses work: autofocus and electronically controlled models are not compatible. Sony E-mount lenses (18.5 mm backfocus) can also be used, provided they are fully manual.
