He really is the best. On the FX, of course, the angle is large (almost a fisheye), but if you have a DX camera format, it will give panoramic photos a fantastic look at 14mm (not so strong girth angle and at the same time a great wide format). Weight for me personally stabilizes the vibrations of the hand in many ways. There are no filters - you can’t walk openly with the lens, so the hood should be removed only when shooting.
