Canon 17-55mm 2.8 IS
Aperture Priority or Manual
(I'm giving ranges because I'm away from the computer with the originals so don't have the exact specs, but these are the ranges I stick with for similar shots almost always)
The last 2 photos are tone mapped hdrs using 3 exposures (bracketed +-2ev), and used qtpfsgui, and balanced using gimp and rawtherapee. Looking back, I feel they're a bit too over processed for my tastes right now. The top two on the other hand were done in either Rawtherapee or Lightroom.
This thread is making me wanting to do a proper photoshoot... it's been too long.
