Summary of TAMRON Lens Utility Mobile

October 2021 marked the release of TAMRON Lens Utility, a dedicated PC software that enables the customization of various functions of select TAMRON lenses to match the video and still photography style of the lens user. Since then, we have received feedback regarding improved convenience from customers wishing to make lens function customizations when shooting in the field. As a result, we have developed TAMRON Lens Utility Mobile for Android OS. Using the TAMRON Connection Cable ⁵, an Android smart device can be connected to a lens to easily configure lens customizations without requiring a computer.
A new function that enables lens operations to be controlled from a smartphone has also been added. For example, the A-B Focus function that smoothly shifts the focus from one preselected subject to another can be setup without touching the lens.
Expansion of functions in the future is possible to make users even more comfortable to try out video production.
