Undoubtedly, the best lens for Alpha with APS-C in its category, while being versatile - you can shoot everything and everywhere. And wide-angle, and almost telephoto. I don’t know about the travel zoom - there you can use some seedy little 28-300 tamron with the mark “fifth grade, well, almost no marriage” - there HA so HA. And with SAL16150, you can work wonders, if your hands grow from where you need to.
