What lenses for my D700?
Hi there
I’ve done a fair amount of research, but too much information has proved a bit detrimental. I am a uni student so I dont have a big budget – but I also don’t want a rubbish lens (for example, the AF-s nikkor 55-200 DX proved to be pretty naff with my D60). I already have a micro-nikkor 55mm, but I would like a lens with autofocus. I mostly do portrait/fashion work. Would love to hear some suggestions 
ps. when I say I dont have a big budget – I mean I cant go over £300! I dont mind buying second hand tho.
The best focal length for shooting portraits would be either the 85 mm or 105 mm lenses.
Full frame cameras shooters use the 70-200 mm f/2.8 as a compromise so they can cover more than just portraits.
