Accessory to make macro photos - shorten the distance the objects and the lens with an extension increase from 35mm to 125mm, i.e. picture ratio from 0.7 to 2.5 (50mm lens), from 0.35 to 1.25 (100mm lens) and from 0.26 to 0.92 (135mm lens).

The Picture ratio can estimated using the following equation:

picture ratio = extension length of the bellows/focal length of the lens

for lenses with focal lengths under 35mm a special inverse attachment ring is neccesary
