How do cheap macro ring flashes perform?

Question

When I last checked years ago, the price of a typical Ring flash unit was approximately $500. Nowadays there are still ring flashes for approx. $500 like Pentax AF160FC, Pentax AF-140C, Canon MR-14EX, Sigma EM-140 DG ...

On the other hand, there are "noname" LED ring flashes for approx. $50. The price is very tempting maybe a bit too cheap. What's the main difference? Are they really that bad?

Answer

Not having owned a cheap-o ring flash, I can only guess what the tradeoffs might be:

  • Cheaper build quality
  • Inconsistent Light Output
  • No "Bang-bang-bang" shooting
  • Little/no camera interfacing (ie no support for Canon's E-TTL)
  • Weaker light output

Now, for $50, if you can swing it, it seems like it might be worth it to first try using a ring-flash and get the hang of it, before moving onto a more expensive solution.

You may also want to look at Strobist. He/They periodically do comparisons on so called "ebay-gear" and give honest, objective feedback taking into consideration price/performance capabilities.
