Tamron Tele Zoom Custom Switch Settings

[Richard A]

I updated the firmware on my Tamron 50-400 today with the Tamron Utility app. It was pretty straight forward. I was thinking I should set the custom button/switch. Has anyone done this on their Tamron lens? I'm thinking of having one setting at infinity focus but not quite sure for the others. Maybe some sort of focus limiting.

I might be out of date, but I didn't think the focus point for infinity was fixed. I thought it varied with different conditions?

That would be dependent on individual lenses I guess. I don't know if this lens qualifies. Maybe it just sets infinity at 400mm. Some testing will be required. Unfortunately, there isn't a huge amount of info on using this app or the settings.
