Wetpixel/Under The Jungle Cenote Workshop 2021

The San Diego Undersea Film Exhibition (SDUFEX) is calling for entries to the festival, which will be held on 6 and 7 October 2023 at the San Diego Qualcomm Auditorium. Full details of rules and procedures are available from the contest’s website, and the submission deadline is 15 June.
The transition of full frame mirrorless cameras from SLR has reduced the number of lens options available to photographers, and given the tiny number of those using them underwater, there are some gaps in appropriate lenses for using with them. Alex and Adam discuss some of the older lenses, including Nikonos, and how some of these may work with the new cameras, while others currently will not.
The results of the 2023 Underwater Photographer of the Year contest have been announced. The winning image is a split shot of an Amazonian River dolphin (Inia geoffrensis) or bota, by Kate Zhou, which was also awarded as the best image from an up-and-coming photographer. Congratulations to her and to everyone that was placed among the winners.
