As an Instructor, you pretty much have to be able to pick up any camera and know where everything is located, or where to find it on the menu. That is why the student is attending your class. So, I not only teach photographic techniques, but I am also able to help my students one on one with the details of their cameras as well. Have a great day!
WOW, and OMG, What will really impress me is that if you also own the following cameras:
Canon EOS 1Ds -Mark III, Canon EOS 5D, Canon EOS 40D, a Rebel Xti, the Canon G9 and the modest Powershot TX1.
I'll FREAK and drop dead! LOL
