I was really impressed by this site and it’s information on DSLR cameras and their operation! There is a great book by the host of the site and I was referred to this page by a colleague who teaches DSLR technology to his students at K-12 level! WWW (wow, where were) you when I was in high school
The information about the lenses, accessories, rigs, recording, and post are very useful. I highly recommend it for beginning and intermediate level students and enthusiasts to check it out.
