That said, should they be called Fast Lenses or Shallow Lenses?

I would call mine: CatEye!

The tapetum and other mechanisms give the cat a minimum light detection threshold up to seven times lower than that of humans. Variation in color of cats' eyes in flash photographs is largely due to the reflection of the flash by the tapetum.

I can't wait for sensors to progress beyond what we have now, making fast lenses less necessary for some shooting scenarios.
