Easy to attach and use. I haven't learned all the features but right out of the box, and set to auto mode, the flash works great. It gives out an even fill light and the model light is good for low light conditions. Nice quality and is simple to put on or take off.

...that photographers shooting close-ups want an affordable ring flash with professional features. A ring flash is the way pro's get that amazing lighting on very close subjects...do you want that too?

This is specifically in reference to the model for Canon and may not apply to the one for Nikon. I purchased one of these and an EF-530 DG Super, also for Canon, expecting to be able to use them with the EM-140 DG as master and the EF-530 as slave on a Canon 30D. When configuring them in that mode, following the directions in the rather poorly written manual, the 530 in each case either fired prematurely or not at all. I finally called Sigma and had their tech walk me through the setup, with the same result. He told me to send them back. I did. Sigma lost them. Finally they sent me two new replacements. The replacements have the same problem, so this seems to be something fundamental and not a malfunction. I have been told that EF-530 DG Supers do work well together in TTL master/slave mode so it seems likely that the problem is in the EM-140. Standalone it works fine and will also work as a master for the manually controlled modes of the EF-530. Between not working as advertised and the poor quality of support I received I cannot recommend this product to anyone.
