The problem with KR is that sometimes it's hard to tell when he is actually making good sense and then other times when he is either totally off base, or he is joking around in a serious satirical way. It's just his style and he fully discloses that he likes to spoof around. I think he likes to get under the skin of folks that spend way too much on stuff they have no real need for or have any idea how to use. That statement might even include him sometimes. Whatever you think, I like reading his stuff sometimes because regardless of what you think about KR, he does make you stop and think and go do research or read up on something to figure it out for sure for yourself.
Worked for you this time, didn't it?!
And I'll admit that I do like to use his definition for L lenses... L means 'Expensive as L'!
