Learning how to use Canon Speed Light on my Canon 70D. Trying to use the FE lock. I now have an exclamation mark in the lower right corner of the view finder. I can’t find out what it means or how to get rid of it. Any help?
Hi There Per the following web site, the exclamation mark is called a warning symbol. http://community.usa.canon.com/t5/EOS/I-…
