Great timing! My wife and I just returned from a cruise visiting Spain, Italy, Greece, and Croatia on Sunday. She had her iPhone 14 Pro Max and I took my Lumix ZS70. Comparing our photos I feel the iPhone 14 did an excellent job and held up well against the Lumix. In fact, if you factor in the ease of carrying the iPhone 14 and its simplicity of use, I would probably choose the iPhone. I was carrying my iPhone SE along with my Lumix, so going to a better iPhone only would eliminate one extra thing to carry. Since we were on guided excursions and there are often crowds, there is little time to set up the "perfect shot". You take the shot as quickly as possible and move on. The iPhone does this well and gives great results. The other big advantage of using the iPhone is that you can immediately back this photo up in the cloud and post it for friends and family to see. We were in Venice on Saturday, the day before Easter, and it was very crowded, especially in St. Mark's Plaza.

This was my first trip with the Lumix ZS70. I normally carry a Sony RX100 vIII which I bought to carry on trips after I tired of carrying my heavier Sony kit/w lenses. The Lumix is heavier than the RX100 and, in my opinion, a little more difficult to use than the RX100. My thoughts now are to sell the Lumix ZS70 and purchase an iPhone 14 Pro. I may keep the RX100 a little longer but I think its days are numbered after having seen what the iPhone 14 Pro is capable of.

Scott Kelby has an excellent book on iPhone photography and has a lot of good advice. I have the Kindle version from Amazon. If you are interested in or thinking about getting into iPhone photography, this is a must-have.

I see field of view and angle of view used interchangeably a lot in photo tutorials. I have always thought that they are very different. Field of view is what you see in the seen. It is more a function of the sensor size for a given lens.
Angle of view is more related to the focal length of the lens. A wider lens ie. 35mm will have a wider angle of view than a 100mm lens.
The reason it is important is because wider lenses tend to have more perspective distortion. One of the reason 85mm is used more for portraiture than the 35mm. You can get the same field of view with both lenses by changing your distance and cropping but the angle of view will be noticeably different. Thoughts?
