I have always enjoyed photography and have spent thousands on SLRs, dSLRs, point and shoots, lenses, flashes, tripods, etc....
Granted, I have taken some wonderful photos with this gear and technology has progressed so much that even my recent point and shoot, a Sony DSC RX100 III, was taking photos comparable to what my full on pro level kit was taking.
Still, the big camera was heavy, bulky and obtrusive in many situations. For this reason, I ditched the dSLR years ago in favor of the point and shoot. Neither my photos nor my enjoyment of taking pictures suffered.
I have always wondered if I would be able to get by with just my IPhone (currently a 7+) but was afraid of missing my point and shoot for certain shots. So, on my last trip, I did a test. I intended to carry both with me at all times and make note of when I reached for the point and shoot over the Iphone.
Over the first week, I noticed a surprising trend. I had days where not a single photo was taken with the point and shoot. I then started to force myself to use the point and shoot. Surprisingly, I found that this action, even as simple as opening the pack and taking the camera out of its case was disruptive and made many moments feel staged rather than spontaneous. For example, I got many surreptitious photos of my wife browsing at a Christmas market in Alba on the Iphone that happened because no one really noticed I was taking a picture.
The quality was similar. Certainly I do not expect a 24 x 36 enlargement, but image quality is more than enough even without shooting in raw. Another benefit for me was no downloading needed. All archived on the phone, organized by date and location automatically.
On one of our final days, a young man we had dinner with had the new Iphone 11 Pro with the triple lens camera. He showed me photos he had taken and I was blown away by the difference between his images and mine. While many complain that Apple uses in camera algorithmic processing to achieve the photo effects that traditional lens do, I was overall very pleased (actually blown away) by the potential of this unit for traveling.
We are going to Tahiti in June and I will be buying an IPhone 11 pro shortly before the trip as my only digital device. Okay, maybe a kindle for reading on the beach. From my first few Europe trips carrying 5 pounds of gear taking up 1/5 of my pack to now carrying a few ounces in my pocket - I am converted.
