Do like this bit
"I need to know the limits of each part of my system so that I can work around them. If I know a lens is softer wide-open, then duh, I know how far to stop it down to get fantastic results. It's the great results I seek; finding the limits is merely a means to getting great results.
The first thing I've always done when I've bought a new camera or lens is to push it to its limits. I find the limits, make a note of it (which is what started this website), and then go out and shoot. I don't worry about it again.
Sadly, many people try to test their lenses, but get disappointed and think they have a defective product when all they've found is its limits, or more often, limitations in their own technique. Let me assure you, every product has its limits, and with digital cameras today, anyone can find them.
Only idiots find something's limits, and let themselves get stuck there complaining about it. It's every artist's duty to find his tools' limitations so he can work around them. Americans didn't walk on the moon in 1969 by sitting around complaining about all the reasons we couldn't get there."
