Solid impresion with itegrated handle. My black 800RF has no handle, but stems from the time when Leitz cooperated with Chiyoda Kogaku , it is in Leica R mount, so it can easily fit CanonEf. I find that compared with shorter mirror teles it i fa easier to focus precisely. It has a smoothly running lever at the front that adjusts the front mirror, so no need to move the entire assembly. It is listed in the Leiitz catalogue, but I do not know whether is was modified and assembled in Wetzlar. Leitz or Minolta must have had quite a challenge to make the entire mount shorter while kkeeping the complicated mechanism for inserting fiters.
