Ultra-compact design Compatible with our high-end compact digital camera RICOH GR IV, the ultra-compact design is easy to carry and can be carried in a pocket while attached to the camera. 2. Simple and easy operation When set to ISO AUTO when the ‘RICOH GR IV’ is attached, the camera supports automatic light control shooting*, in which the guide number and ISO sensitivity are controlled by the camera according to the subject distance, enabling photography using flash light without compromising the quick shooting performance as a snapshooter. *: When attached to cameras with terminals other than the X-contact point that differ from the layout of the GR IV, including conventional GR series cameras, only full flash will be available.
