Abstract
Accessory lens structures for cameras are described. For example, an image capture device may include a mother lens assembly including a first stack of lenses; an image sensor positioned at a first end of the mother lens assembly and configured to detect images based on light incident on the image sensor through the first stack of lenses; a conversion lens assembly including a second stack of lenses, wherein the second stack of lenses is afocal; and a conversion lens mounting apparatus configured to removably attach the conversion lens assembly to the image capture device in a position over a second end of the mother lens assembly, opposite from the image sensor, such that light incident on an outer lens of the second stack of lenses will be refracted through the second stack of lenses and the first stack of lenses to the image sensor.
