Did you know that the iPhone 7 Plus’ much-vaunted second telephoto lens will NOT activate if there isn’t sufficient light? This includes indoor locations with artificial lighting where there you might think there’s more than enough illumination.
Don’t believe me? Take a look at the video below where YouTuber Martin Keen proves it and explains why (the telephoto lens has a smaller aperture, so just can’t handle lower-light situations, while the wide-angle lens alongside has a sufficiently wide aperture).
In other words, tapping the 2x zoom button on the iPhone 7 Plus will only digitally zoom in unless you’re outdoors – or unless you’re in a particularly brightly-lit indoor location. Image quality will therefore be reduced significantly.
Apple kept quiet about that one, didn’t they?
