  1. Buy compatible lens
    Here’s a fact . Not all lens compatible on your Nikon’s DSLR body. A Canon lenses will not work on your Nikon camera. So you may pick only Nikon’s lenses and 3rd party lenses that compatible with Nikon ( eg: Tamron for Nikon , Sigma for Nikon etc )
  2. Focal length requirement
    Focal length equals image distance for a far subject. Lenses can be categorized by their focal length. Pick what suit best for your need :
    - Normal lens (35mm to 85mm )  : useful for portrait or if you love street photography
    - Wide lens ( 28mm or lower ) : if you love shooting landscapes
    - Telephoto lens ( 100mm to 300mm ) : for portrait and sports / action
    - Super-Telephoto ( beyond 300mm) : sports and wildlife (birds , lion etc)
    - Macro lenses ( 60mm – 200mm ) : special lens designed and optimized for macro photography ( flower , bugs etc )
    - ‘Special effect’ lenses such as Tilt shift and Fisheye lens
  3. Autofocus requirement
    This is because Nikon D3100 doesnt have focusing motor on its body. Nikon D3100 able to use autofocus only on AFS lenses but not on older AF lenses. So you may want to re-check before buying a lens.. do you need autofocus or not ? Personally , for me , autofocus is necessary
  4. Prime or Zoom ?
    Zoom lenses are favoured by most photographers because of its function, however zoom lenses usually have higher f-stops than prime lenses, and this means that they usually leave less light into a photo . A prime lens on the other hand doesn’t allow you to zoom at all, your limited to one focal length. You may think this sounds rubbish, however there are many advantages to using a prime lens over a zoom. First of all prime lenses usually have lower aperture values and some of them go right down to f1.2 this means that a lot of light can enter the camera lens this is especially useful for low light situations.
  5. Extra features / technology
    Learn lens acronyms before buying a lens. Lens manufacturer uses their own abbreviation for what is essentially the same feature eg  image stabilization feature on Nikon labelled VR ( vibration reduction ). Canon called them IS (for Image Stabilization )
  6. Budget
    Check your budget .. when it comes to lenses, you DO get what you pay for :) so choose wisely
