- Focal length – Defines the lens’s angle of view. 17-55mm in the zoom lens and 35mm in the block lens. Lenses upto 35mm are called wide lenses. Lenses between 35mm and 70mm are called normal lenses. Lenses above 70mm are called tele lenses.
- F stop or Aperture – Describes how much light the lens gathers. The image shows F2.8 in the zoom lens and F1.4 in the block lens. Lower the F, more the light absorbing capacity and better the lens.
- Image Stabilization – Some lenses include optical stabilization units to counteract the blurring effects of hand shake. Canon calls is IS (Image Stabilizer), Nikon calls it VR (Vibration Reduction), Sony calls it OSS (Optical Steady Shot), Tamron calls it VC (for Vibration Compensation), Sigma calls it OS (for Optical Stabilization), Panasonic calls it O.I.S.(Optical Image Stabilization), PowerOIS and MegaOIS.

- Budget – Once you know this, then you which lens to pick up to suit your pocket.
