The stock 16 x 5.5 has the same angle as a 10mm on 2/3". The standard 2/3" zooms tend to be 8mm at the widest. Of course, the angle of view at the min distance on both the stock JVC lens and the standard zooms is reduced due to the breathing effect when focusing. The much reduced breathing on the W/A lenses then become a major advantage, because you're not losing around 10 degrees on your angle of view (as happens on the standard zooms) when you focus at the min distance on the wide end of the zoom. |

The Shooting angle calculation table can assist you with figuring it all out.

Thanks...I was missing the sensor size. At 3.5mm, isn't there some barreling?

No, there is no "barrel" effect with the 13x3.5 at full wide.
