Is ISO 102,400 Useful—or Even Possible?
Every introduction of cutting-edge camera technology brings a set of new possibilities—some insanely valuable, some with questionable merit. What really matters to me is, “What will the technology allow me to do that I can’t already do?” If something is just marginally better than what I already have, I’ll likely stick with what I’ve got. But if it will allow me to make pictures that I couldn’t make any other way—or nearly as easily—then the line forms behind me to get my hands on it.
