LED ring flash
Let there be light!

Now years later, and a revolution in the LED technology I got myself that ring flash, cheap... and it is not quite the same.
The ring flash seems and feels like plastic, it doesn't have the weight of quality. This LED flash is made of 32 LEDs. They can be adjusted on the scale - from the highest value, and then in steps down to 1/64 of full power. It's powered by 4 AA batteries. And being LEDs they don't eat up the batteries as fast as they would, compared to real strobes. For less than £20 you can find these LED flashes of several different brands looking very much the same.
There is a flash function, and a continuous light. Also, you can have the full ring flashing, or only half, left or right, (or up or down, depending on how you turn the ring flash.)
In the box I got in the mail, there were 8 or 10 rings to be screwed onto the lens filter thread. With that many different sizes, there was one for each of my lenses. On that ring, the ring flash is mounted. It simply just clicks on to the ring and can be turned easily, so you can have left and right, turned up and down instead. The plastic box with the buttons and led indicators, and most important the batteries are just to be fitted on the standard hot shoe. This of course is how the flash is triggered.

My judgement on this LED ring flash is that; Don't buy it is not worth it. I would recomend the Godox Macroflashes instead. They are named MF-12 and I mention those in the newly added page, macroflashes.

Information For doing macro photography a ring flash is good for casting light all around the subject. While the LEDs make this model affordable, the quality is better in the classic ring flash with strobes. I do not know if you will find these suitable for your jobs, but if you expect the same quality as the strobes give you, then you will be disappointed. I bought one, and I rarely use it.
