Review on K&F Concept Camera Flash - KF-570 II Speedlite with LCD Display: Canon and Nikon DSLR Compatible by Dustin Ramsey

I bought this ring flash for macro photography and was amazed by the results after just a few shots! The interface is user-friendly (although you can read the manual if you're not familiar with Flash). I liked the ability to independently control the power of the two parts of the ring. Also the different lighting modes (continuous/sharp) are very helpful to get the right focus, especially in low light conditions. Conclusions: Really good quality/price.
