Currently there are 16 native Telephoto Zoom lenses for Sony A7 IV and 15 of these lenses are autofocus (AF) type.
A7 IV also has a sensor based image stabilization system which means that all of these lenses will be stabilized when used on A7 IV.
Since Sony A7 IV has environmental sealings (Weather Sealing), you may like to couple your camera with one of these 15 Telephoto Zoom lenses with Weather Sealings.
