This adapter enables use of M42 x 1 - mount lenses with Basler Racer, Beat and Boost cameras, which do not include a lens mount. 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.)
Thickness: | 7 mm from lens contact to camera body contact point |
