https://community.sony.hr/t5/alpha-nex-interchangeable-lens-cameras/battery-grip-a68/m-p/2324819#M5840 <P>I do a lot of Astro photography, using a sky tracker, and have upgraded to an A68 (Lens compatibility). Th&nbsp;battery grip from my previous Sony no longer fits - thanks, Sony. It doesn't even have contacts inside the battery compartment, so I can't adapt it.
