It's just silly to talk about the kitchen photo... I was not taking a kitchen photo... I was taking a sample photo to demonstrate a technical issue hehehehehe, it's not a "standard" photo... it's not a choice I would have made, or a photo I would take for any reason other than to "take a quick shot to test something". Can we stop talking about it as if I took a road trip to my kitchen and decided to take a glorious UW photo of the sink? hehehehe it's hilarious...
So, in any case, rbrylawski I think you're missing the main point... even in the Grand Canyon on a perfect day, your iPhone UW photo will capture a larger piece of the view, but it will still have less detail and look worse than if you took the same shot with the W camera. It's just the way it is... the UW camera in the iPhone is just not as good as the W camera.
Trust me there are incredible UW lenses in the world, matched to a great sensor they will provide great detail and sharpness. Such combination can cost as much as a house... so I know it's not something easy to fit in a phone and sell for less than 2000 USD.
They certainly didn't use a great UW lens/sensor combination in the iPhone, and Apple wasn't clear enough about how much less quality the UW they used is when compared to the W. That's basically the only problem with this matter, Apple marketed the UW in a way that is not correct, it is vastly inferior to the W camera.
To be fair... probably other phones with UW cameras have similar or even worse performance... I'm not sure about that but I would think so. However, that is no excuse for the way Apple advertised their UW implementation.
