I have an underwater camera bag DiCAPac WP-570 I use for my Sony RX100 v5 (probably works for all RX100's). When this camera turns on the lens sticks out a little more than 2". The WP-570 has a lens area that also sticks out, but sometimes the water pressure can make the lens catch on the underwater bag and then turn off. To stop this, I designed in Tinkercad, this cylinder thing that rests against the camera front and makes it so the lens can fully stick out without catching anything. I sanded the inside of this thing so the lens does not catch on it. This thing does not get in the way of taking a picture, even at wide angles.
