We're excited for the announcement of a fantastic new ultra-wide angle lens from Canon, the RF 10-20mm F4 L IS STM. A high quality wide angle lens is an essential tool underwater photographers and videographers alike.
Canon suggests that the RF 10-20mm provides at least as good as - if not better - image quality compared to the hefty EF 11-24mm F4L at less than half the size and weight. We think this lens will be a great option for shooting wrecks, big animals, and models underwater.
The "IS" in the product name stands for "image stabilization." Canon promises up to 5 stops of in-lens image stabilization specially calibrated to reduce "fluttering" (blurring) at the edges of the frame. This news is very promising as edge sharpness of a rectilinear lens behind a dome port tends to be a problem for us underwater.
Price & Availability
This awesome new lens comes with a pretty big price tag of US$2,299. But if you're going to invest in photography, a good lens is the best place to do it. We would rather shoot a sharp lens on a less expensive camera body than the other way around.
The Canon RF 10-20mm lens is expected to start shipping in November 2023. We will update our Lens Port Charts with recommendations for the new lens as quickly as possible.
