Sony Attachment Grip

The Sony AGR2 is a attachment grip. Sony describes it as easily fits to your RX100, RX100 II, RX100 III, and RX100 IV. It is a first-party Sony part, so it fits and behaves the way the camera expects rather than the way a third-party copy approximates.

It measures 1 5/8 x 1 9/16 x 17/32 in (43 x 39 x 13 mm), and weighs 0.2 oz (5 g). Sony moulds it in TPE+PC. Sony sells it as a matched accessory for the bodies and lenses named above; check that list against your own camera before ordering, because Sony changes mounts and shoe types between generations.
