Hmm… I have spent the last few days fretting over my Canon 420 EX flash. Seems it wouldn’t zoom the flash in conjunction with the lens as it is supposed to. Turns out I don’t know how to read a manual. (After 40+ years, why start now?!)
Way near the end of the manual, under the heading of Bounce Flash it states:
- The flash head can be turned upward and/or sideways.
- With bounce flash, the flash coverage is set automatically to 50mm, and the 50mm autozoom position blinks.
I originally thought the flash was broken. It’s a good thing I didn’t go out and by that new Nissin Di622 flash… or not.
