@tech@zwo#44177 I guess anyone with a 1600mm might hold off upgrading as the filters for that suit a micro 4/3 sensor size. I'm not personally looking for a 294mm (as id rather the latest sensor tech of the 533/2600) or a 2600mm (as it will need larger filters).
I'll keep a lookout & hopefully zwo releases something in the future based on the new sensor tech for 4/3 Mono market.
