The Canon AD-E1 is a Multi-function Shoe Adaptor that adapts conventional weather sealed foot hot shoe Speedlites to Multi-function shoe cameras, whilst maintaining dust and weather resistance. The new Canon hot-shoe adapter allows for Canon cameras that feature the new 21-pin multi-functional hot-shoe to be reverse compatible with older styled hot-shoe mounted accessories. This hot shoe adapter is compatible with new Canon cameras with the 21-pin multi-function hotshoe, for example, the Canon EOS R3. This hot shoe will allow new 21-pin multi-function camera users to use accessories with the traditional 5-pin Canon hot shoe mount. Weighing no more than a few grams, the adaptor takes its power direct from the camera. When attached it allows you to fully concentrate on getting the shot, whether thats outside in challenging conditions or in the studio.
