High ISO & Points To Ponder

[Kevin Gallagher]

 I was sent a link to that I think is a very interesting little article on fast glass (F2.8 F4) vs the availability of the very high  ISO settings that are now so common on our digital cameras.

 Must admit that I was in the "It's No Longer Needed" camp on the fast glass.

I still like using fast lenses, though not for the same reasons as the article's author. I like the artifacts that a lens at the edge of its capability introduces into photos. I'd add curmudgeonly that "fast glass" starts at ~f/2.5.
