M/F Mamiya C330 F mostly with 135mm lens, or 180mm for tight head shots and either Fuji Pro 160S or 160C depending if it's a male or female portrait,For slides I use Fuji Astia or Provia, although I love Velvia for a lot of my outdoor landscape or street work I find it too strong in colour saturation for portraiture.
35 MM 85mm 1.8 Canon FD ( I love this lens so much I recently bought a second one in case the existing one breaks down) I also use the the FD 100mm 2.8 and the FD70-150 4.5 zoom. My film choice is the same as for M/F.
