I had an X-T4 and an 18-55 lens. I was very pleased with it. I traded in the X-T4 for an X-T5 as I wanted more crop headroom for wildlife even with my 100-400 lens. I then decided to trade in the 18-55 for the 16-50. The X-T5 has IBIS so it does not matter that the 16-55 does not. I am very pleased with it. Can you try a 16-55 on an X-T5 without purchasing?
