I have been trying to figure out how to set my camera/flash to slave mode. Can I use my Canon 430EX II as an off camera flash with my Rebel T1i? If so, how would I accomplish this?

  • Do you mean wirelessly, or with cables? Also, do you want TTL automatic flash exposure control or do you want a manual "dumb slave"? – mattdm Nov 5 '11 at 22:32

Unfortunately, your camera does not offer built-in wireless control of your flash. In order to control your flash off camera, you need to purchase the Canon ST-E2.

At this date, only the Canon 7D, 60D and 600D (Rebel T3i / Kiss X5) offer built-in wireless control of flash, but I assume that will change over time.

There are solutions from PocketWizard, and Radio Poppers that also support E-TTL remote, off camera flash support, but they tend to be a bit more expensive, but a great alternative if you have a challenging environment or shoot (around corners, long distance)

If you wish to remotely manually fire your flash (meaning not use E-TTL), you can get the 'Cactus' or 'eBay' triggers, that will allow remote firing of flash, but will not support the in-camera settings and control.

    Doesn't the 60D offer flash controller as well? – ysap Nov 5 '11 at 23:30
  • Good catch, forgot about the 60D – cmason Nov 6 '11 at 15:31

    I think the 600D does too – David Nov 7 '11 at 8:53
  • I think the 650D (T4i) does also. – Jeff Jan 16 '13 at 19:44
