subha Posted March 15, 2011 Share Posted March 15, 2011 <p>Can I use 420EX flash in slave mode without actually mounting the flash on the Hot Shoe. I want to use it for macro photography. </p><p> </p> Link to comment Share on other sites More sharing options...
PuppyDigs Posted March 15, 2011 Share Posted March 15, 2011 <p>Yes, that is the normal use of a slave. Flip the bottom switch to "slave," mount on stand and trigger with a master (ST-E2, 550EX/580EX series or 7D/60D popup).</p> Sometimes the light’s all shining on me. Other times I can barely see. - Robert Hunter Link to comment Share on other sites More sharing options...

PuppyDigs Posted March 15, 2011 Share Posted March 15, 2011 <p>It has to be a popup that pulses E-TTL coded commands. The 7D and 60D are the only two with such ability thus far.</p> <p>You can use the OSCII or III or one of the inexpensive Chinese clones on fleabay to get the 420EX off shoe while retaining E-TTL.</p> Sometimes the light’s all shining on me.
