Because the weight is dependent on the lens (or no lens), all
weights are detailed at the Optics tabs for both Tau2 and Quark2
Most Tau2 cameras with wide field of view (WFoV) lenses weigh
70-72g. Weights of the narrow field of view lens (NFoV) configurations
can be seen at the Tau2 web page
under the Optics tab, bottom of page.
Quark2 weights can be seen here.
