This was made on a poodlewalk yesterday with Heather Petty, and Kayla and Maleko:
Heather, who is a Nikon DSLR photographer, had a new Sony premium compact camera with her, which she was trying out before she started to use it for her underwater photography. It was a Sony Cyber-shot DSC RX100V --with a fixed lens I think. It is compact in the sense that Heather could put the camera in her pocket.
The Sony DSC RX100V's point and shoot characteristic makes it ideal for underwater photography.
