The Tamron 17-50mm f4 Has a Really Great Feature

I've looked at the press release for the development announcement of the Tamron 17-50mm F4 Di III VXD a few times now. And still, I've got so many more questions than I do answers. I've been doing photography for almost 20 years now, and when I look at the focal length, I'm reminded of an 18-55mm lens.
