Its the Telephoto Lens taking over when you zoom, which will give blurry pics
There is an app called ProCam 3 which can deactivate the telephoto or the digital and choose which lens to use. But the Apple built in camera app just automates itself as to which lens it will use when you zoom
Zoom only really works when you tap the x2 icon on the zoom tool onscreen, but any more will cause an argument between telephoto and digital zoom lenses.
I have an iPhone 7 Plus, which i bought to replace an iPhone 5s
I use the camera to photograph amulets which measure roughly 2 x 3 cm and upwards
To show the textures of the clay, i have to close up with zoom
In my experience, the iPhone 7 Plus goes blurry as soon as you zoom more than x 3, and close in on a small object
As soon as i get close in, the telephoto and digital zoom lenses start arguing about who is the one who is going to to take the picture, and the image starts to skip left to right on screen as the two lenses start to quarrel. Either way, the picture ends up blurry as heck, and evcen a x 3 zoom on an object at mid distance is like your rabbit picture, namely blurry and lacking in lustre.
My iPhone 5s in comparison, takes excellent photos up close, and look better than the ones from the iPhone 7 Plus.
It seems i made a mistake thinking the 7 Plus can be used for my miniature arts product photos, because the telephoto and digital dual lenses, are more optimised for taking pics of people at a party, landscapes, and selfies. The iPhone is not a device for selfie making, family pics and social networking, and is not usable as a professional product image taking camera
My iPhone 5s beats the saddle off the iPhone 7 Plus camera. In addition i have an Ölloclip lens for the 5s which has a x 12 and a x 15 macro lens, which gives me beautiful closeups
The iPhone 7 Plus is a piece of rubbish in my opinion i cant even listen to music with headphones, as i am not paying200+$ for a pair of wireless headphones, or the ridiculous prices for the headphones with lightning connector.
