First and formost this IS NOT A RING FLASH - it is an LED RING LIGHT! That explains why it is so much cheaper. However it still does a useful job. I will mainly use it to take macro photographs of flowers and fungi - and it seems to do an excellent job with small specimens in dark woodland environments. However, you neither get the intensity or 'speed' that you get with a genuine ring flash - so its probably not as good for moving subjects or subjects where maximum depth of field is required - such as small insects. I have used it for insects and it helps - but not I guess as much as a dedicated ring flash. However, for the price it is a very useful bit of kit - simple and uncomplicated to use - simply switch it on and off as required. Certainly will be in my camera bag this autumn.
