      Comments about Vivitar 800MR 800mm f/8 Telephoto Mirror Lens for T-mount:

      I had great expectations to this lens, espesially sine I use a 500 mirror Nikon lens. But the focus is not good. I tested it on both a c-mount web camera and my
      Nikon D300.

      I suspect it not to be focused properly, and I might try myself to move the secondary mirror...which is hard to do on this type of telescopes.

      I use this lense for documentary work, I love it people don't notice you at all and you can catch really interesting moments, it is one of the most doifficult lenses I have ever used, but is worthy every dollar I payed for it

      Comments about Vivitar 800MR 800mm f/8 Telephoto Mirror Lens for T-mount:

      The lens is stamped 900mm f/8 but the box shows it as and B&H is selling it as an 800mm f/8.
      Using a beanbag or RIGID tripod, a remote trigger, and locking up the mirror before shooting, I get a reasonable image IF I get the focus correct. Using the camera's rear LCD in magnify mode is about the only way to get accurate focus, so don't try imaging any moving objects. Total focus travel is about 1/4 turn of the 4" barrel from infinity to minimum distance, so micro-adjustments are required to get focus. Really needs a MUCH longer focus travel to be usable.
      Metal body appears to be rugged and nicely constructed / finished, no dirt or other blemishes visible on optic, and the T-Mount is functional for a constant aperture lens. Lightweight so does not require a tripod mount, but it would be better for stability if one was available.
      As someone noted on DPR it also helps to set up a high contrast and saturation preset on your DSLR for this type of lens.
