Yongnuo WJ-60 Macro Photography LED Ring Light for Canon Nikon Sigma

Not a bad little gadget. works great for close ups and macro, but you have to be indoors. if you are outside or anywhere bright, it doesn't fill as much as you would expect. Then again, its not $500.I really like that the mounting rings are metal and screw onto the lens very easily. They allow the unit to be attached/detached quickly without having to screw on/off. I'd give it 5 stars for value if it were brighter.

I have another LED Ring Light, which has batteries attached by wire. Stopped using it when I got this one. Also the fact that it has adapters for multiple lens is a huge money saver. The brand is a very good one, too.

Worth the buy if you are in need of something cheap.

Too much vignetting from using it on the lens, useless. Works ok on the hotshoe, but kinda misses the point to use it like that.
