After being a Nikon guy for almost 35 years myself, I just got back from the Galapagos Islands where I took all photos with an IPhone XS Max. I am sure five years ago I would have argued there would be no way I would have left my DSLR behind. My reasons were based on changing priorities. The trip was a family trip, read grandchildren 6 to 13 yrs, that changed my literal focus away from photography and more to family interactions. Were I to be on my own the choice would have been different. That said, the cellphone allowed me to take wonderful pictures in the normal flow of the days and had I wished I could have used it while snorkeling as well. I have no regrets about the decision.
