Did you not read it when I pointed out the iPhones allow multi-focus point merely by clicking on the points you want to select? No need for a "'oy-stick' interface. Use your finger on the screen image and select while composing the shot. I don't think you are paying attention.
A pro camera has dual sets of controls for shooting in portrait or landscape mode. You can adjust key settings like aperture, shutter speed, etc. while composing using the knobs/dials.
The iPhone has these controls RIGHT on the screen. . . in either portrait or landscape mode. . . there for the photographer to use while composing the shot. No need for antiquated "knobs and dials" when you have digital controls.
An iPhone has the battery life to shoot hours of video. . . or thousands of photographs. They really don't take much battery power. Again, you are not paying attention.
Who needs multiple memory cards when every photograph taken is instantly saved to MULTIPLE devices and to the iCloud? It cannot be lost. (Frankly, sometimes with a few I've taken, I wish they would!) Within seconds any photograph I take is also on my iMac, in my iCloud account, on my iPad, and on my MacBook Air. Who gives a rap if known to be flaky SD cards crap out on you? Come into modern times. The ONLY places you have an argument is in interchangeable lenses. . . and even there there are lenses that can be added to iPhones. I do wish for a good portrait lens. . . and in the ability to blow up the photographs into super-huge detailed prints.
I keep pointing you to professionals who are using the iPhone in professional settings. . . and you keep arguing it cannot be used in a professional setting. They are DOING it. That says a lot more about you and your mindset than the equipment.
Trust me, I DO get your point. . . but you are failing to get the point as well.
Cell phones will do fine to get snaps of grandma blowing out the birthday candles, or selfies on vacation... but they have a very long way to go to be any threat to the professional camera/lens market.
