Re: Peak tech
To be fair, having multiple lenses with differing focal lengths in a phone is huge technical innovation. Its not Apple innovation, Android phones have had these, and even 4 tiny lenses, for quite a while.
Once you use a phone with ultra wide and 5x optical zoom in addition to a standard lens there is no going back, it really is a game changer as far as leaving a DSLR at home and just making do with a phone. To fit the lenses in such a small space requires some clever tech like periscope lenses, and the image quality for such minute sensors is a technical marvel.
