TAMRON Lens Utility™

Select AF/MF

Switch between Autofocus and Manual Focus
This function switches between AF and MF using the Focus Set Button on lenses that lack an AF/MF switch. This makes operation easier when shooting scenes that require frequent use of AF/MF switching.

A-B Focus

Lets you smoothly and easily shift focus from one subject to another
This function allows you to shift focus at a preset speed, as is frequently done when recording video. Get exactly the kind of visual expression you want, for example, by slowly shifting the focus from a distant subject to one closer to you, or by guiding the gaze of the person viewing the video. Use the Focus Set Button or Remote Set Button to record two preset focal points in advance. Afterwards, a simple press allows you to shoot while moving focus automatically and at a set speed; you don’t have to worry about the speed blur associated with manual focus, and you can achieve stable visual expression.

Focus Preset

Move focus to a prerecorded focal point with one press
This function allows you to preset focal points, for example, to deliberately defocus a subject during a video transition or to access a focal point for night photography. You can set the focus travel time when recording video. You can also set focus on a preset focal point at maximum speed with a single press when taking still photographs. This feature broadens the range of your visual expression.

Astro Focus Lock (Astro FC-L)

Function to support focusing for astrpphotography
Focal Point will automatically be fixed at infinity to assist you in finding the focus point for astrophotography.
*The focus ring will be disabled until Astro FC-L is released to prevent focus deviation due to incorrect operation.

Focus Stopper

Focus range can be set with the lens alone during movie recording
Limit the MF travel range between any two focal points that have been recorded beforehand. It is easy to change and set the position of the focus stopper, you can create images without worry about 「Over Passing」the focal point.

Focus Limiter

Choose the focus search range to best suit your photography situation
The Focus Limiter helps you to avoid accidental focus on a subject, for example when there is something located in front of your subject. By limiting the focus range, when the focus moves unintentionally you can quickly focus back to your subject again.

Ring Function (Focus/Aperture)

Switch function from focus adjustment to aperture adjustment
This changes the Focus Ring Function from focus adjustment to aperture adjustment using the Focus Set Button.

MF Ring Rotation

This function changes the direction the focus ring rotates during manual focus.
You can choose the direction that the Focus Ring rotates. It can be set to the same direction of rotation as your camera manufacturer’s lenses or the reverse.

MF Method

This function adjusts focus movement when using manual focus. You can choose between “Non-linear,” where the amount of focal point movement changes based on how fast you rotate the focus ring, and “Linear,” where the focal point moves based on how much you rotate the focus ring. Some lenses allow users to adjust rotation as well, to offer more personalization.

Assign Function from the Camera

Functions of the camera body can be assigned to the Focus Set Button
This reassigns the Focus Set Button to activate the function that you assign to it via the camera body.
