Pentax WG-3 Lens information

The WG-3 is equipped with a fixed lens with a focal range of 25-100mm giving it a 4.0 x zoom which is definitely not very good but it can be valuable in some circumstances.

At it's widest 25mm, it provides an aperture of f2.0 and that is beneficial in low light events and capturing good bokeh. It is going to also make it easier to go with a much lower ISO to capture cleaner shots. For the long end, 100mm comes with f4.9 making it very sluggish and you will have to go with slower shutter speeds.
