Telephoto Lens,長焦距鏡頭,85mm或以上的都算長焦距,一般人講TELE通常指200mm或以上.

[AhQ]

Most people see 50mm lens is standard lens (the viewing angle close to human's eye sight angle)

For lens which focus length longer than 50mm, for example 80mm, 100mm, 200mm ........ people call them Tele. lens

For lens which focus length shorter than 50mm, such as 35mm, 28mm, 17mm ....... people call them wide lens
