I waited a couple of months before writing a small review, powerful, robust device used with the Nikon D 500 Nikon. It is possible to adjust the intensity of the 2 semicircular flash lamps and turn on 2 LEDs (not very powerful) for focusing. The series of rings to adapt it to various lens diameters is excellent. Exceptional quality-price ratio

Simply brilliant! After several days of use in macro mode, I can only be delighted. The power output is perfect, adjustable of course. Coupled with a macro lens and a Nikon D7100, it's a real joy to use.
Delivered in a practical carrying case with its set of adapters, I can only recommend it for less than 100 euros, it's a bargain.

Does what it says on the box

Works a treat with Nikon DSLR and 100mm Macro lens, makes all the difference to lighting close up subjects.

I just got the ring flash (Nikon fit) and have been practicing with it. So far, I really like it. It's a little heavy to hold for extended periods, so a tripod is recommended. My biggest complaint so far is that I can't understand the manual! The translation to english has so many grammatical and spelling errors that it is impossible to figure out what is trying to be said! Instead, I am just trying settings using experience along with trial and error.

The one I received from amazon was broken as only people light worked so I returned it immediately .I did look around and got same ring light elsewhere so feel I can review it and it’s pretty good for the money .I’m very satisfied it was just a shame the one I recieved was faultyGreat value for money

Bought as a gift for family member so not sure how well it performs yet. Arrived on time but the internal package was found to be damaged, dusty and grubby as if it had been on the shelf for some considerable time. Doesn't look good when you've bought the item as a present to someone. Disappointed that the goods have arrived in this condition.

I am still trying to properly understand how it works. The instructions are really badly translated and almost incomprehensible. But I must say the product itself seems robust and when I manage to get the settings to where I want them, works like a dream.Please get your user manual better translated.

Excellent product - works well on my Nikon professional cameras. Flash WB colour and spread of flash perfect no issues so far.Do not be put off by the low cost of the ring flash it is packed/presented/protected well and has a few extra features not on other ring flashes..

This flash is a very affordable tool to explore close up photography with a very good range of settings. It’s has packed almost everything you need to know before you move on to the top of the league ring flashes.Specifications :Flash control: Insulated Gate Bipolar TransistorFlash power : GN14 (ISO100)Working range: 20cm ~ 5mFlash configuration: Two flash tubes can be fired singly or togetherExposure Control: TTL, Manual, Multi-shotFlash Ratio Control: ±6 stopsFlash power settings (manual): full power to 1/128th power in 1/3 stop incrementsIndependent control of tubes.Colour Temperature: ~5500kExternal interfaces: Camera hot shoe, Flash Sync. port, external charging portPower sources: 4*AA alkaline batteries or AA Ni-MH batteries (not included)Extra Function: Power saving, over-heat protectionSize of control unit: 143*73*61mmSize of flash unit: 130*126*28mmWeight: Approx 465gThe flash also comes with a stiff case which is brilliant at keeping everything together and safe.Accessories include adapter rings for different lenses filter thread size: 52mm, 55mm, 58mm, 62mm, 67mm, and 77mm, if nine of these for your lease the seller offers to contact them and they’ll send out the one you need.The ring flash fits to the lense as any filter would, just screw on and attach the flash with small button on the side. You press it again to release it.The back panel is clear to read even in now light as it’s backlit. The flash can also be fired the conventional sync lead.Be avare using wide angle lenses as it gives quite obvious vignette and by saying wide I mean 24mm and wider, you’d probably start seeing vignette some, but I only tested this flash with one fixed zoom wide angle lense.I really enjoy exploring the capabilities of this ring flash and it hasn’t disappointed me in any way, especially taking in consideration the price. It’s great value for money. Just one thing, I just wish someone marked the a and b flashes , as I keep confusing them. But I guess, that’s just a matter of getting used to it.
