I received a Canon 430ex ii for Christmas and am still trying to learn flash photography with my t3i. I am 3/4 of the way through Bryan Petersons book Understanding Flash Photography, so I'm semi comfortable with shooting in manual with the flash in manual mode. My only issue is that I cannot figure out how to get my 430ex to give me a distance reading. I saw it once, but I don't know what/how I did it. I have switched the Custom Settings a few times trying to figure it out, but still no indicator reading. I used back button focus, so I switched that, but still nothing. It's not crucial, but it would be really nice to have so I don't have to guess at my aperature based on distance to subject. Is it possible that something is wrong with my flash? Any ideas or suggestions would be a great help!! Thank you!
