48mm T-Mount for Nikon Z

This high precision T-mount adapter is expressly designed for compatibility with Nikon Z mirrorless cameras and features 48mm T-threads. The adapter is constructed from CNC-machined black anodized aluminum, providing a durable and vibration-resistant design for astrophotography applications. With an optical path length of 39mm, the adapter achieves a combined back focus distance of 55mm when used with Nikon Z cameras, making it compatible with M48-threaded corrective optics like flatteners and correctors without requiring additional adapters. The 48mm diameter provides reduced vignetting for maximum light transmission and optical efficiency.
