I quite like their tutorials. They are short, simple, direct, and straight to the point - and they also are perfect for idiot newbies like me and also the indie/DIY budget challenged folks as well. As we all know - lenses are the black hole of gear - man I can't even calculate all the time and money wasted on getting 'what I want ' ( how many 'cheap' or not so cheap 50's have we all bought and sold?). Stuff like this helps a lot. Primes rock!
