I'm soon buying a Canon or Nikon full frame. I like the Canon & Nikon 24-70 f2.8 lenses, but they have no vibration control. Tamron's similar lens does have 'VR', but glass is said to be not as good, and image quality is important to me.
I do mostly candid, hand held shots, have a 'steady' hand, but need advice. Would it be smart to invest in a Canon or Nikon lens for my purpose, or would hand held be risky out at 70mm zoom?
