OK... In order of use: I currently shoot Canon, Nikon, Sony and Olympus. However, seeking to broaden my horizons, I got a couple of Fujifilm X-T4 bodies. One came with the Fuji 16-80mm kit lens, and for the other, I decided to go out on a bit of a limb and investigate the new Tamron 18-300 f/3.5-6.3 Di III-A VC VXD lens. It is available to Fuji X-Mount and Sony E-mount bodies.
With a focal range of 18-300 on an APS-C body, it offers an equivalent Field of View of 27-450mm, which is pretty massive! I had always been aware that any lens with such a focal range as that had come at the cost of several types of compromise to performance, and of course it does, but not as many nor as much as I feared and depending upon one's purposes they may or may not be acceptable. For MY purposes, I was considering this for the ultimate walk-around unit, where I would not have to change lenses. Still, after extensive research, including reading or watching MANY reviews, I decided to take the plunge.
So, it arrived and I am impressed within the context of its purpose. If you want some sample reference material:

However there are lots more reviews out there.
I decided to try it out in a very casual test to see how it behaved, and I must say, I thought it did ok.
