Hi All,
I am looking into ring flash for my two macro lenses: Sigma 150mm and Sigma 50mm. I was thinking about the Sigma EM 140 Ring Flash. Please let me know what you think about this flash or a similar product that you may have used.
My second question is about the weight of the flash when mounted on the protruding barrel of lenses such as Sigma 50 / 70 / 105 or Tamron 90, etc. It just seems like a bad idea to place weight on such parts. Um... What do you think? (Sorry, but that's the best way I could think of wording my question. Hope you don't mind. )
Thanks,
Erez
