The TG-5 takes SD, SDHC and SDXC cards and uses a UHS-I interface. OM SYSTEM specifies UHS-I U3 or faster for 4K, high-speed movies and Super Fine bitrate; a V30 UHS-I card therefore makes the sensible default. Faster UHS-II cards can still work as SD cards, but the TG-5 cannot use their second-row UHS-II bus contacts, so spend on reliable UHS-I capacity rather than expecting a UHS-II speed boost.

Buying tips
- For TG-5 4K, high-speed movie and Super Fine modes, select UHS-I U3 or faster as OM SYSTEM specifies.
- Use a full-size SD/SDHC/SDXC card; the camera supports UHS-I, so a UHS-II card gains no bus-speed advantage in-camera.
- Format a newly purchased card in the TG-5, and copy files to a second location after each water or travel outing.
