Advice for ring flash

[simon4]

Hi everyone, Some advice please, I am considering a ring flash. Either Canon's own MR-14EX TTL or Sigma EM-140. I normally use canon gear but its the price that sways me towards the Sigma, but is it as good as Canon. Do you have any images with one of them or used any of the two. Thanks, Simon.

I use MR-14EX and am very happy with it. I think they are pretty similar as far as the specs are concerned. But I've never used the Sigma, so I'm unable to compare them. One thing you should find out is; if you already have a Canon flashgun(s), can EM-140 trigger it (them) wirelessly, or vice versa? I haven't been able to find out the compatibility, so it's worth checking it out. (or I'm sure someone here will be able to answer it).
