A lens accessory that fits between the lens and camera body and extends the focal length of the lens, often by 1.4x or 2x, at the cost of reduced light, decreased image quality, and slower autofocus. TCA: Transverse (lateral) chromatic aberration or lateral colour. Colour fringes that worsen the further the image point is from the optical axis ...
A photographic lens or objective is an integrated system comprising one or more simple optical lens elements, which produces an image of a distant object. The main article for this category is Photographic lens .
