Welcome to another OM System photographer. I'm in Sarasota.

For years we have been told to not use your cameras teleconverter. That is true for DSLR and most of the Mirrorless, maybe not all, but OM System and Olympus. When using RAW capture the 2x digital teleconverter is a crop guide. Om your RAW editor like Lightroom you are free to recrop and use and area of the sensor. Have you have used it and how?
