OK, with my 18-55 kit lens (even if not the greatest in terms of aperture/speed)... and my 50mm f/1.8 that I love... I'm pretty well set in the 50mm-ish and less realm, at least for now.
What about lenses on the other side of 50mm? ...link me up to the ones you simply love love LOVE?!

Purty please?! I'm open to whatever (fixed or not)... just curious to know what your faves are for the whole "shneaking up on your kiddos without them knowing it and snapping candid shots from across the yard/playground that you can embarrass them with in 20 years" thing. KWIM?

Thanks!
