Only Single Finger operation for triggering, - above. At 120mm zoom is possible with the Canon.
Nice would have been a simple plastic cap to protect the front glass against possible scratches during transport.
Good protection against moisture, sand and other, not only to prevent accidental actuation of the rear buttons / switches. If you snorkel with diving glasses, setting the Canon is almost impossible. Keeps water from well. Exaggerate and use it as a pure underwater body, I would not, however. For an occasional short pleasure to just below the water surface, pouring rain, dusty storm but super.
