Holger puts it rather well:
"Wide angles are tough: Optical aberrations increase rapidly with the angle of view, and even a sophisticated design leaves a lot for the amateur optics tester to pick at and complain about ("poor edge-sharpness!") on the Internet discussion boards - something no high-end manufacturer likes to read about his product."
"For the love of the Great Flying Spaghetti Monster, they're only binoculars, and if they didn't exist, we'd just have to stand closer to stuff!" --Sancho
