Equipped with full-length external threads, the connectors allow for the optimization of the position and angle of connected components, with the tube length varying upon directional adjustment. Lock rings are included (not provided with SM1-T025), enabling hand-tightening of the connected assemblies. These adapters feature a light-tight design, making them ideal for integrating with existing lens tube systems or cage systems.(2) Additional lock rings can also be purchased separately to limit the external thread engagement depth of SM1 threaded components. Multiple lock rings can be used to lock lens tubes independently, such as when using cross polarizers.(3) Available in a range of thread lengths.AssemblyApplication Examples
