No, the Sony A6700 is not compatible with the Sony Tough CEA-G480T 480GB CFexpress Type A.
Sony A6700 (ILCE-6700) supports only SD memory cards (UHS-II compatible) per Sony's own Help Guide. It has no CFexpress slot. CFexpress Type A requires a dedicated CFexpress Type A connector and physically cannot be inserted into an SD card slot. This pair is a physical connector mismatch.
