This adapter enables use of M42 x 0.75 - mount lenses with Basler Racer, Beat and Boost cameras. Recommended for use with the Racer 4K and larger models. (M42-mount lenses can be used with 2K models, but you'll find that C-mount lenses cost less.)
Extends path by 7 mm, so racer and beat will have 16 mm total flange-back distance. (Measured lens flange to sensor.)
