The Carl Zeiss 16-70mm 1:4 made by Sony is an expensive standard lens for the Nex / APS-C E-mount line of cameras. It combines a very useful focal range with a decent moderate speed and size.
All in all I think it is an interesting lens but it has some weaknesses which will be a deal breaker for some photographers.
