This adapter allows you to connect a camera with a Sony E mount (NEX) to a coma corrector or field flattener with an M48 male thread. Its short optical length will provide enough optical space for an additional component such as an off-axis guider or filter drawer. Additional adapters will be required.

The adapter is 10mm in optical length. This is 27mm less than the standard E-mount adapter.

Designed for Full Frame sensors, the wide M48 thread minimizes vignetting.
