Ken's technical reviews *can* be good as long as he sticks to the facts and doesn't drift off into the lunatic fringe and injects opinions tainted by bias. He also pushes a lot of photo technique approaches that most pro photographers I've spoken with write off as rubbish, e.g., his assertion that you don't need to shoot RAW... all you need is JPG. I followed this advice many years ago and quickly came to regret it. So, approach his reviews with a great deal of caution... and be sure to look elsewhere for other info to be sure you get a good flavor of what you're trying to learn.
