It's impossible for me to tell if Opteka is an originating manufacturer of lenses (like Sigma, Tamron) or a branding arm of others (like Vivitar). But they have produced some unique optics for the mirrorless cameras, all manual focus designs.

These lenses tend to be available in all mounts of APS-C size or smaller.
