Aloha, I'm a wildlife and landscape painter looking for a super/zoom with fast shutter speed primarily to capture wildlife (birds). Preferably a bridge camera like the Sony RX10 IV. However, due to the age of this model, anyone know if a newer one is set for release? Or is there a different replacement? I tested a Nikon P1000 and the reach was amazing, but it couldn't keep the focus and the shutter speed wouldn't keep up either so I returned it. The RX10 has been highly recommended to me, just don't want to purchase if an upgrade is right around the corner. Any thoughts? Thanks much!
