by Jim Richardson – Owachomo Bridge | Milky Way


“the Milky Way is always the same exposure: 90 seconds, f/2.8, ISO 3200 will always get you a nice, bright Milky Way. Or, 60 seconds, f/2.8, ISO 5000 will work. Or 30 seconds, f/1.4, ISO 1600 works well, too. But note that there are no 14mm f/1.4 lenses. There is one 24mm f/1.4 lens and it can produce some fine star images, though with somewhat limited performance in the corners. The problem to be solved with that lens is getting it in focus, which is fiendishly difficult at f/1.4 in total darkness. It must be absolutely in focus. (Hint: Autofocus won’t even come close.)”
