A lens that is indispensable for the use of digital SLR cameras and mirrorless interchangeable-lens cameras . Among these lenses , the telephoto lens has an impact on the appearance and allows you to take more dense photographs . Also , there are times when you ' re taking a picture and you just can ' t get close to the subject , right ? Even in such a case , you can get closer to the subject by using a telephoto lens . This time , we will introduce a lens compatible with Micro Four Thirds from among the telephoto lenses .
The image sensor , which greatly affects the image quality of photographs taken with a digital camera , is said to be the heart of the camera , and is divided into three sizes as shown in the figure above . If you want to capture a wide range , you need a lens with a shorter focal length . Also , keep in mind that even if you use lenses with the same short focal length , the range that can be cut out differs depending on the sensor size . Generally , the larger the sensor size , the better the image quality , and the smaller the sensor , the higher the telephoto effect .
Micro Four Thirds is a common standard for interchangeable lens digital cameras , and was jointly proposed by OLYMPUS and Panasonic . Cameras equipped with Micro Four Thirds are lightweight and compact . It also has a powerful image stabilization function . Also , it is a nice point to get both body and lens relatively cheaply . Cameras equipped with full-frame sensors are inevitably expensive due to the large body and lens .
Generally , a lens with a focal length longer than 70 mm is called a telephoto lens . It is possible to take a large picture of a distant subject that you cannot approach . Also , since the angle of view is narrower than that of a standard lens , it is very useful when you want to shoot a distant object , or when shooting a presentation or athletic meet when you have to shoot from a distance from the subject .
