37mm Adapters
In this section will be a range of 37mm Telephoto adapters from a number of brands including Century and Sony.
Telephoto adapters are best known for making distant objects appear magnified. This effect is similar to moving closer to the object, but is not the same, since perspective is a function solely of viewing location.
If you were to take two images taken from the same location, one with a wide angle lens and the other with a telephoto lens it will show identical perspective, in that near and far objects appear the same relative size to each other.
But when comparing magnification by using a long lens the telephoto shot appears to compress the distance between objects due to the perspective from the more distant location, therefore getting you closer to the shot.
