1. There are a ton of resources out there for Canon & Nikon SLR lenses, just wondering if there is the same thing for Canon & Fujinon ENG lenses.

2. Also, Canon has a method to their madness in naming their lenses. (i.e. you can tell from just the model number if it is for 2/3" or 1/2"; if it has a 2x; if it is HD…)

Is there a method for the madness of Fujinon lenses?

Whats the difference between a Fujinon A15x8BEVM & A15x8BERD & A15x8BDEVM?

Both the S20x6.4 BERM-SD & A13X6.3BERM-SD start out at the same wide FOV, but one can zoom much farther than the other (20x to 128mm vs 13x to 81.9mm). Does the "A" or "S" mean one is better optically than the other?

3. Lastly, does anyone have a list of what "SD" lenses still look pretty good for "HD"?
