Not being a camera person, 13mm to 65mm or 30mm vs 300mm doesn't mean much to me. If you say a lens with "5X zoom" I think 0 magnification to +5X magnification. If you say "5X zoom range" without specifying the range, I also think 0 magnification to +5X magnification. What Apple states seems straightforward to me, but my definition of their statement is different than their intended definition.
You are interpreting this from the perspective of someone with significant camera knowledge. For someone without that knowledge, it's a bit misleading. As I stated previously, I can't say if that is intentional or not and I am not going to speculate, but saying "-2.5 to +2.5 optical zoom" would be more clear than the way Apple has stated this.
That is in no way more clear. What the above poster stated isn’t only applicable for people who know about cameras. It’s painfully obvious that 5x zoom range means 0-5 as in going from the zoomed out wide angle to the zoomed in telephoto. This entire thread is based on a disingenuous idea that it doesn’t make sense. Any reasonable person understands what that means or doesn’t care to understand what it means.
