I looked at various options from cheap constant light to pricey Nikon ring flash. This K&F unit is a true ring flash and works brilliantly on my Nikon D750 with 105mm Micro Lens. It is well made and has produced some superb results and I am very very happy with my decision.

love it

Works very well with Nikon d550Seller was very helpful with queries relating to attachment to a sigma macro lens

Needed a flash unit to use for dental photography. I've read some reviews, that other buyers used it for this purpose and gave it a try. It works just fine.Also, I had some questions and product support was very helpful to answer them.Perfect flash unit for the price.

This ring flash is pretty easy to use. The controls are fairly straightforward which is just as well as the instructions are terrible. The two preview lamps are brilliant and really helpful. The flash at full power is perhaps a little over the top at close settings and can be very bright. But once power was set at a lower setting the quality was beautiful. Soft enough yet bright enough. As an experiment I set it all to fully automated and the camera to P mode. The exposures were pretty much perfect. I’m quite impressed. For the money it can’t be beat I reckon.The manual says the overall weight is 465g but it’s quite well balanced despite the clumsy looking hot shoe unit. I didn’t notice any weight issues nor any imbalance. The main ergonomic issue is that the very thick connection cable has to stretch underneath the lens which is a little annoying but that’s easy to remedy. Just turn the ring unit so that top is bottom. You just have to remember that left flash becomes right flash.The system works well and is logical. It’s easy to fine tune exposure too as it has lots of flexibility.The light is hard at full power on the Sigma Art 50mm but when it was at 1/32 and 1/16 it was really nice. My tests have been limited so far but really promising.

Excellent product, ideal for macro photography. Works perfectly on a Nikon D5300 with 85mm macro lens. Nice case too.

Only bought against customer reviews. Very pleased with all aspects, useful bag, build quality and performance. Makes macro into a total pleasure. Not sure how much more the expensive units would add to the results.A good purchase, no experience on how long this unit will last but initial reaction is good.

Product arrived before the delivery date, I have used it for macro photography with great results. Item is well manufactured.

Produces some pleasing lighting effects but supplied instructions may as well be for another product as you have to work it out for yourself.

Does everything I hoped it would. Very happy with it.
