In theory, the quality of a 2x zoomed photo on the iPhone 7+ should be about the same quality as..

    if we took the shot at 1x from the same perception as the zoomed version, right?

    Yes it's the 'software zoom', ie. digital zoom that's rubbish.

    Hmmm....not really, but it depends on how picky you want to be, and also what question you're asking.

    Are you asking if using the second lens will be the same as just standing closer to your subject?
    Or are you asking if the quality of the shot is the same as using the standard lens, but zooming in?

    Setting aside the technical differences in the capabilities of the two new lenses (different apertures), then:

    If using the second lens will give the same result as just standing closer to your subject using the standard lens (so called 'zoom with your feet')...
    In this case, the answer is no, they won't be the same image. You will get different images especially on the background, as the relationship between background and foreground changes. See here for the an example of this, the guy is using a DLSR and different lenses, but the principal remains right.
    (it goes on a bit, so the suggest you skip to the result which starts about 5m20s)

    If the quality of the shot is the same as using the standard lens, but zooming in x2?
    In this case, the images will be similar, but you get twice the number of pixels by using the zoomed lens, rather than cropping the image. Given the high pixel counts these days, you won't notice that difference unless your printing / viewing it at a large size. There are technical differences to do with the amount of light hitting the sensor etc, but I won't go into that.

    At the risk of being a photo-bore, then yes there will be differences....but for someone who just wants to stick something on social media, taking a 'throwaway' snap and never really look at it again, then essentially it would be the same as zooming in.

    If you want options to take better quality images from further away when you can't get closer (at a concert, or animals in a zoo etc), the zoom will get you a better better image to start with, which you can then edit further on down the line.
