I'm surprised that in no reviews of the iPhone 18 camera there is mention of the bad quality bokeh, it has heavy ring shapes that looks like what you'd get from a cheap catadioptric lens.
Edit: e.g. the tree in one of the images in the page: <a href="https://www.dxomark.com/wp-content/uploads/2026/09/PoleHDR_Deep_AppleiPhone18Pro_DxOMark_05-00.jpeg" rel="nofollow">https://www.dxomark.com/wp-content/uploads/2026/09/PoleHDR_D...
Zoom in on the tree leaves, it's very visible on those. They appear as green rings, slightly lighter on the edge, giving it the appearance of a ring. You can also see it very clearly in the spots of sky between the leaves, they appear grey with an almost white outline.
