Photography that takes advantage of the superiority of large-aperture lenses
Communication between the photographer and the model in portrait photography is very
important. For this reason among others, lenses between 50mm and 135mm are often used, in order to maintain a certain distance from the model. The standard zoom lenses which are
often sold together with camera bodies cover this focal length range, and are therefore
generally suitable for this type of photography. Sometimes, however, it is necessary in portrait photography to use a large-aperture lens with a larger maximum aperture than is offered with such zoom lenses. It goes without saying that getting the most out of the lenses you already have is a good thing, but the powerful effect afforded by a large-aperture lens is the ne plus
ultra of interchangeable lenses in SLR photography. The first element is the beauty of the blur. The wider the aperture, the shallower the depth of field becomes, increasing the blur in the out-offocus areas. 85mm lenses, which are often used or portrait photography, can deliver an impressionistic background blur effect since they are much brighter than zoom lenses. Single focal length lenses generally have a brighter maximum aperture than zoom lenses, making them ideal for photography using a shallower depth of field. And of course if you want to reduce the blur a bit all you have to do is close the aperture the required amount, which gives large-aperture lenses a broader range of expressiveness.Download Tutorial PDF now.
