I have seen it reported that the 21mm has a smaller 60 degree FOV, unlike the rest at 67-68 degrees. Is there any truth to this? Seems to be becoming the popular belief on CN. But maybe just many people repeating the same misinformation originating from the one source.
I had the 21mm Stratus and did not notice a smaller FOV. In fact comparing with the 19mm Pano it seemed about right.
