I have a friend who is a quite basic amateur photographer who is looking for a single walk round lens for her nikon D5100
She bought the twin lens outfit because it was cheap and now finds changing and carrying 2 lenses a nuisance.
Does anyone have any experience with the Tamron or Sigma 18 200 I do you think the VR function is going to be hugely important to her and there is a noticeable quality drop ?
Most of her photos will just go on facebook and possibly an occasional 8x10 print.
She is fairly price conscious in her buying habits

( Total NIKON bigot )
