Are they the movie camera lenses?

  1. [​IMG]I got a few of lenses, I do not know if they are movie camera lenses. I will appreciate that you give me information about them.[​IMG][​IMG]

  2. Aimin, it would help a lot in indentifying your lenses if you gave some description, such as the brand(s) and what markings are on them and their size.
     
  3. He posted images, but apparently photo.net's software didn't like the links. Maybe because they are https ?
    If you right click on the missing image symbols and "open in new tab/windows", they appear OK.
    I have no idea what the lens is intended for. Obviously some custom application.
     
  4. I cut and pasted the link I saw and got a story about a teen mother and her baby.
    does not look like a movie lens to me

    Got this pic - looks more like a special-purpose scientific lens, although the glass may be the same as a movie lens.
     
  6. There's nothing special about a movie lens vs. a camera lens. Movie lenses are typically calibrated in T-stops rather than F-stops and their back focus distance and frame coverage may be different (depending on the format they were designed for), but fundamentally they do the same job.
    If you measure the size of the image circle, that will probably tell you something
     
  7. Going to the links, then looking back and forth, reveals a brand name of "TotalVision" and that they are calibrated in F-Stops, not T-stops. Some research reveals that they are some sort of Anamorphic projection lens, and may be relatively rare.
     
  8. I have no idea what it fits, but appearance wise, it looks very well made. Precision and precise are the words that come to mind, not to mention it's built very, very solidly.
     
  9. The chances are that this is an adapter (Lotus comes to mind) that fits into a camera video/mot pic camera and takes on Nikon or some other type of lens/es.....and yes, they would be well constructed.

    Except that movie lens will cost you at least 3 times as much....
