whats the difference between a macro lens and a telephoto lens?

Answer 1

Macro photography refers to close-up photography; the classical definition that the image projected on the "film plane" (i.e film or a digital sensor) is the same size as the subject. On 35 mm film (for example), the lens must have the ability to focus on an area at least as small as 24×36 mm, as this is the size of the image on the film. This is known as "life-size magnification" or simply 1:1.

In recent years, the term macro has been used in marketing material to mean being able to focus on a subject close enough so that when a regular 4×6 inch (102×152 mm) print is made, the image is life-size or larger. This requires a magnification ratio of only approximately 1:4, more easily attainable by lens makers.

In photography and cinematography, a telephoto lens is a specific construction of a long focal length photographic lens that places its optical centre outside of its physical construction, such that the entire lens assembly is between the optical centre and the focal plane. A regular lens of a focal length that is longer than what is considered a normal lens is not necessarily a telephoto lens. A telephoto lens has to incorporate a special lens group known as a telephoto group ; nevertheless, non-telephoto lenses of long focal length are often informally referred to as telephoto lenses. The angle of view created by a telephoto lens is the same as that created by an ordinary lens of the same specified focal length.
use for distance.

In general terms, a telephoto lens is one designed to have a narrow field of view, resulting in images that are "closer" to the subject. They also flatten the perspective visually. The main use is to bring the viewer closer or to cut out extraneous surrounding details. The main uses are for portraiture, bird photography, landscape photography when one element is to be isolated, etc.

Macro lenses are designed to focus closer and good ones also are designed to have minimal distortion at these close focusing distances. Some kinds of macro lenses are specifically designed to give a flat field, for photographing flat objects such as coins or stamps.

As mentioned above, the term "macro focusing" is often applied to zoom lenses indicating that they can be focused quite closely to the subject. However, there is no comparison in quality between these zoom lenses and true dedicated macro lenses when working close.

Generally, true macro lenses will indicate the reproduction ratio, as something like 1:4 or 1:1. A 1:1 macro lens means that they can focus close enough to render the subject at life size on the film or imager.
