Actually, except for the Duo (which uses the low-res Lepton sensor) all of the FLIR cameras (Vue, Vue Pro, Vue Pro R, Duo Pro R) use the same Tau 2 sensor as the XT, and come in 336 or 640 resolutions. To say that they’re not as sensitive as the XT simply isn’t true — they’r’e the same camera. The advantage to the XT is that DJI does the integration work for you. Where you could run into differences is between radiometric and non-rad versions, as the R versions have extra factory calibrations done to ensue measurement accuracy, but that won’t necessarily impact image quality. Full disclosure: I work for FLIR and have been involved in development and testing of all of these.
