Hello, can D700 travel with 24-70 lens?

Yes, 24-70 covers a wide angle to a medium focal length, which can be said to be the most practical focal length. Of course, it's a little worse than telephoto. If you don't use much telephoto, you can use 24-70. If telephoto is used more, consider a lens such as 24- 120/4 VR or 28-300 VR. However, of course, if the zoom factor is large, the image quality will definitely decline. 24-70/2.8G can be said to be Nikon's best standard change now.
