I was hoping I wouldn't feel compelled to chime in again on this subject but it pains me to see so many users being misled about the real issues with the iPhone Pro camera's limitations. Those green orbs/dots and floating artifacts (call it ghosting) are NOT what the nice folks defending Apple here would have you believe is predictable, 'traditional' and expected "Lens Flare."
YES, almost all cameras and lens systems will produce lens flare when shooting towards high key lighting sources (like the sun). BUT what us iPhone Pro & MP users are frustrated with are the more defined, easily created in many lighting environments, harder edge orbs and floating artifacts that all too often blemish the captured images and videos.
I've been waving my sword at the Apple Tech windmill since 2019 regarding this technical issue and have gotten absolutely nowhere. Hope for improvements or elimination of the glitches in 2020 or 2021 never materialized.
For the record, I have been in the graphic arts since the early '70's and continue to work to this day as a Creative Director, ad agency owner and also a freelance photojournalist. I wish Apple success in solving this problem.
