Exercises in Extreme Focal Lengths
Minolta X-20 and Leica Televid 77 #1



  ·  This series of photos were taken with the tiny Minolta X-20. It is a 2 megapixel, 3x zoom, using Secure Digital memory cards.

  ·  The physical size of the lens opening suggests this camera could be very well suited for use with a wide variety of scopes to multiply the focal length.

  ·  No mounts are available for this camera, and without a filter ring with threads another method of positioning the camera is necessary.

  ·  These photos are all handheld. All the photos here were made by holding the camera up to the lens of the spotting scope.
