Yes. My 'normal' camera kit for a wildlife shoot is now my Nikon D850 + 200-500mm lens and my iPhone 12 Pro. The iPhone is great for capturing snaps of people, nice locations, etc, during the shoot although if I was doing a dedicated non-wildlife shoot I'd pack alt lenses for the D850. I think the iPhone is actually better for capturing casual video and I use LumaFusion to give myself an on-phone video editing capability that is comparable with (say) Premier Elements. Again, if was shooting wildlife video I'd pack a tripod and a dedicated video head, but this is a massive weight commitment.
