Sigma EF-610 DG ST Electronic Flash and Sigma A00424 Flash Bounce Reflector for Canon EOS 60D, 60Da, 7D, 6D, 5D, T5i, T4i, T3i, T2i, T3 and SL1 Digital SLR Cameras

I have a canon 6d and it works when mounted but didn't work with my wireless triggers. So I'll order another pair of triggers (I had a cheapo kind that I used with my t4i) and will update with 5 stars if it works then. But I only took it out, took 3 pics so I will have to put it to use over the weekend and use the features...such as upping the power, lowering..etc..I will be back to update. But it works on the mount so I'm assuming it should be all good shooting TTL. Will be back to update soon

Very good
