I recently purchased the Canon EOS R7 and EL10 flash. I took it on vacation and was in some caverns and it would not focus. I also had the camera on Program. Why would it not focus? Did I not have it set right? It focused fine outside the caverns...
Thank you so much. I am trying to learn the EOS R7. Also, I try to stay away from using the flash whenever I can as I don't understand how to use flash. Your response helped me a lot.
