    Looks like you aren't a fan of fisheye lenses... talking about correcting the distortion and mentioning that you don't own a fisheye. But they do have their virtues, too.
    Fisheyes do bend straight lines at the edges of the image, but they keep the shapes of the objects there more natural than rectilinear ultrawides. If there is a ball near the edge of the image, it looks like an egg through a rectilinear wide-angle, but in a fisheye image it stays round.
    Rectilinear lenses keep the shape of a planar object correct when shot straight towards it, but to do that it has to stretch the edges, because those areas are seen from an angle. And then three-dimensional objects get distorted. Distortion is just different from what a fisheye does, but it is there.
    Fisheyes are made with different projections, and stereographic lenses keep the shape most accurate. Other projections squeeze the edges more.
    If you take a fisheye landscape image keeping the horizon in the middle so that it remains straight, you get a wide image where the objects have their natural shapes, and you don't even notice the fisheye effect. But I understand that sometimes you want to defish the image, when wanting to straighten some lines that don't look nice when bent.
    I think the easiest way to find the best value for defishing for your particular lens would be to shoot sraight at a brick wall or some other grid. Your demo image in this video wasn't very easy to interpret :)
    BTW I do like the style of your videos. Nice!
