INTRO Project: Getting to Know Your Camera, Exercise- Focal length and angle of view

In doing this exercise I have found that the "standard" focal length i.e. equivalent to the same view as my eye is 50mm. Given some of the stuff I've heard about crop factors on DX cameras, I half expected it to be 50mm x 1.5 but this is clearly not the case. I need to do a bit more research to fully understand the impact of the crop factor.
