For those who want to take a swim with Nikon’s latest 1 System mirrorless camera – the J4 – the company is also releasing both an underwater housing and speedlight. The WP-N3 housing lets you take the camera up to 45m underwater and supports several 1 System kit lenses. It also has a port for connecting to a strobe, such as the new SB-N10, which has a maximum depth of 100m and works with the already waterproof AW1, as well.
