The lack of wide angle doesn't bother her as she likes to do street photography & artistic crop shots and keeps saying she needs a good zoom. In fact she's never taken the Nikon 12-24mm F/4.0 out the drawer. We need a reasonable walkaround / holiday lens and can't justify buying an 18-200 as well, infact I think it would be too short for her in some cases and with the 70-300 she'd definitely need to carry two lenses. I eventually want the 70-200 for the D700 but would never take it on holiday anyway. I think the 28-300 will be a decent compromise for now.
As said though, there are many mixed reviews around about it and it's not cheap.
Thanks lads.
