Retra is a European company best known for their optical snoots and other innovative accessories for the underwater photographer, such as the uTrigger underwater remote release.
Although I had a lot of high-priced cameras along on my Solomon Islands trip, I also decided to take along the less expensive and friendly Canon G7X compact and the Fantasea G7X housing. The Canon G7X has had a lot of play in photo news sources as a “G16 replacement” and answer to the popular Sony RX-100.
The Canon G7X sports the same sort of 24mm (35mm equivalent) f/1.8 lens, and large 1” sensor that should give it the image quality of m4/3rds cameras, and a competitor to the the Panasonic LX-100 and other similar high-end compact cameras. I wanted to get a feel for how it stacked up.
