I'm loving my new iPhone 7 Plus, which I picked over the regular 7 size primarily for the dual camera setup. Never really been a fan of digital zooms but this one does a halfway decent job of keeping the details relatively crisp, at least up to 5x. The 10x example below shows the flaws, but isn't totally horrible.

Here's some un-retouched comparison shots done in afternoon light - with the car doors closed.
