The latter being of particularly important historical note.Īccording to the Leica Accessories Guide, bright-line or Albada-type viewfinders were originally called sports finders due to the benefit of being able to see a subject enter the frame-lines within the viewfinder. The result is viewfinder that is often at least as bright, or brighter than most newer built-in finders, as well as frame-lines that are projected onto the scene and are easily visible wherever there is ambient light.
They also feature a concave mirror that focuses light onto printed or etched frame-lines. Albada’s bright-line finders contain multiple glass lens elements in order to replicate the focal length of the taking lens. He developed several types of viewfinders that were made both as accessories and built-into Contax cameras of the period. Van Albada came up with bright-line viewfinders in the early 1930’s while working with Zeiss. Unlike early viewfinders that consist only of wire frames of appropriate sizes or even simple optical viewfinders that contain a magnifying lens element, bright-line finders are tiny optical treasures.ĭutch designer L.E.W. I have tried only a handful but am pretty committed to what are known as as “bright-line” accessory viewfinders. Over the years, many different manufacturers have offered many different types of accessory viewfinders that have taken on numerous forms.
