Eastern Bluebird: Kennebunk, Maine, USA — The other way to get impressive results with the iPhone SE 2020 and the Sirui 400mm mounted on the Moment thin case, is to use 60fps 4K video clips and capture frames after the fact. Since I am still in the experimentation phase with this phone and lens (and case) combination, if the bird cooperates I generally try to shoot some still frames, using ProShot at 1/500th or 1/1000th of a second when shooting hand-held, and then switch to 4K video for a few seconds or more of video. I use Lumafusion on my iPad to select and save frames at the full 4K resolution. It is quicker to just take a screen shot in the built in video player, but then you are limited to the resolution of the screen, and, if you crop at all, to even less pixels. I process the captured frames as I would any image, in Polarr and Apple Photos. The results are never going to equal the output from my Sony Rx10iv, but the more I play with the Sirui 400mm on the iPhone, the potential I discover in it, as a photographic tool.
