Pentax WG-3 GPS Lens specifications

The WG-3 GPS offers a built-in lens and a focal range of 25-100mm making it a 4.0 x zoom which is not at all exceptional but it is likely to be convenient in certain conditions.

At the widest 25mm, it provides an aperture of f2.0 which will be ideal in low light circumstances and capturing good bokeh. It would also let you go with a much lower ISO for getting crisper photographs. With the tele end, 100mm comes at f4.9 making it fairly sluggish and you will need to go with slow shutter speeds.

Pentax WG-3 GPS Video specifications

The maximum video resolution on the Pentax WG-3 GPS is 1920 x 1080 and it can capture in MPEG-4 and H.264 format. 1080p resolution gives a great balance between quality versus file sizes but FULL HD won't leave you with much room to downsample.
