The imperfections and aberrations of older lenses are the very strengths that differentiate them from modern lenses. Additionally, a fully mechanical lens is likely to take longer and be cheaper to repair than modern focus-by-wire lenses. With old lenses you can also change the camera system, or your mount can be retired and your lenses will not become unusable. In extreme cases, some mirrorless lenses require firmware updates for each new body. So even if the mount is retained, the lenses won't stay on this update list forever (for example, Nikon's new E lenses are not compatible with cameras that are only two generations old). Fotodiox employs professional photographers in Allen areas of development and design to create products that are built to last. The Pro Series adapters are designe.
