Currently there are 8 native Telephoto Zoom lenses for Fujifilm X-T5 and 7 of these lenses are autofocus (AF) type.
X-T5 also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on X-T5.
Since Fujifilm X-T5 has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 5 Telephoto Zoom lenses with Weather Sealings.
