      5.0 F 1.25-inch to M/F T-Adapter

      Pros:

      Cons:

      Comments:

      This part fills a very specialized need for me, and does it well.

      I wanted to use a 1.25-inch male threaded lens as a nosepiece for a filter wheel with a female T-thread. It works, and provides essentially a 0mm effect on focal length for my application.

      The adapter threads fit, The knurled edge allows for easy attaching/detaching. The anodizing is flat black, but is only cosmetic for me because the adapter is hidden from my light path.

      The adapter does exactly what it is supposed to do, and should work for others.

      5.0 A fine way to hold a focal reducer.

      Pros:

      Accurate,Lightweight,Easy to Use

      Cons:

      Difficult To Focus

      Comments:

      I bought this to connect my .5x focal reducer to my camera. It works fine, and gives a full disk view of the sun, but in order to bring it to focus you'll probably need a set of spacer rings.
