Some experts have fixed focus when shooting a wedding, but they still suggest using a zoom lens. 24- 105 is just right.

In fact, telephoto is still necessary. If the stage is far away, the photographer can't stand on the stage and shoot, and the photographer will kick you down.

It also takes 70-200.

Of course, Nikon's is the simplest, a 28-300, and Canon's 28-300 is also good, but it is big, heavy and expensive, and few people recommend it.

If you meet a demanding master, please ask three or four photographers to shoot the wedding, and it will be easy. The division of labor is clear, and a wide-angle person is responsible for shooting the scene.
