Sinclair Focusing Magnifier


James A. Sinclair & Co. Ltd

2x - 4x magnification by variable separation of the elements. Sliding focusing.

3 Whitehall address.

Sinclair made a series of focusing magnifiers all of similar design, each had a long tube enabling it to be used inside a focusing hood. The magnifier inverts and reverses the image, i.e. against a rear focusing screen the image will be seen correctly. The high magnification results in a lot of aberration and colour fringes, focusing on cross-hairs and an aerial image may be easier than a ground glass.

  • 1925 Magnofoc, 12x magnification.
  • 1926 High Power, 8x.
  • 1929 High Power, 6x.
  • 1932 High Power, 4x.
