Main effect:
Teleconverter - Defect
Teleconverters can extend the focal length of our lenses, but there are sacrifices. First, the aperture is sacrificed, and the aperture becomes smaller. Originally, the focal length is multiplied by the magnification, and the maximum aperture is also multiplied by the magnification. After using a 2x teleconverter for the f2.8 aperture, the maximum aperture becomes f5.6; At the expense of image quality, theoretically, the more lenses there are, the greater the impact on image quality, not to mention the additional section; when using, because the focal length becomes longer, the depth of field will become very shallow, if you are not careful, the focus will be lost. run away; autofocus work will also become less sensitive, and manual focus is required in many cases, and the difficulty of focusing is relatively small when the magnification is small; in addition, the focal length becomes longer, the aperture becomes smaller, and it is difficult to avoid image blur when shooting by hand. , so many times a tripod is necessary.
