*At the 70mm setting, it's possible to shoot at the close range of 0.27m when manual focus (MF) is set on the camera. However, results may be less than optimum since image quality decreases in peripheral areas. For more details, please visit this website: https://www.tamron.jp/en/support/guide/closeup.html

** Length is the distance from the front tip of the lens to the lens mount face.
*** The circular diaphragm stays almost perfectly circular up to two stops down from maximum aperture.
