So, it's raining out, and forecast is rain next 5 days! I figured I would try out the new camera inside with grandson and my 430exii speedlite. Now, I know I used it off-camera before, with my 7D. So I spent about an hour trying to figure it out on my new 5D before I realized there is no built-in wireless trigger!! DUH! So what do you all recommend for a trigger? I don't do a lot of flash, but I want to lean more about OCF. Thanks!
