[0.095 lb] The controls on the falsh are easy to understand and use right out of the box. Works great with 430EX as slave with Canon 100M 2.8L. It is bulky but as a special use flash, you would expect that.

[49mm] Easy to use and make adjustments. Like the high-speed sync. Very good lighting on the subjects.

[49mm] I am an amateur who dabbles in event, street, and sports photography. I wanted to move into portraiture because I get a lot of requests this time of year to take (free) prom pictures of the debs in the 'hood. I needed a softer light and could only afford one purchase. The results with this unit, even combined with simple ambient light were just what I wanted and, frankly, startingly good. It was plug-and-play and continues to work without issue. It does require that red-eye (and pet-eye) be removed in post, but that is very simple. I now think that I am a better photographer than I really am, but at 67, I'm okay with that.

[49mm] I bought this to replace an older cheap ring light that just stopped working. It is quality built, and I love the iTTL for my Nikon. The last one did not have iTTL and I had to use it on manual mode. The refresh time is fast, the adapter rings work for all of my lenses. Overall very satisfied with this unit for both Macro and fashion photography.

[49mm] First of all, I purchased this ring flash to be used on a nikon 200mm F/4 macro lens. I always wanted this lens and finally decided to add this lens to my nikon family of glass. Now I have a new photographic assignment, that well require a ring light because I well be photographing artificial iris patients. As soon as I received the ring flash it went right on the 200mm without any problem using the 58mm adaptor ring (included) with the nice case that holds all of the adaptor rings as well as the command and flash unit. Simple to use and understand, and perfect exposures with a very small learning curve. I well be using this flash for all kinds of macro opportunity to use it both inside the studio, and outside as weather permits.

[0.095 lb] I've begun experimenting with outdoor night macro photography. The images are amazing.

[49mm] Exactly what I wanted for my Sony alpha 7riii

[49mm] I have only had this ring flash for three weeks and I have fallen in love with it. I purchased it specifically to illuminate my water drop/splash photography. Contrary to many reviews indicating the lack of power, this flash has plenty of punch to light up my work at f/11, giving me ample depth of field. I am using the ring flash as a single light using the left and right tubes set a 1/1024 power resulting in a 1/30,000sec flash duration, plenty to freeze the splash action. Se attached image. I recommend this unit for serious professional Macro work.

[0.095 lb] It is quite useful for fast macro setup and controls are easy to use. I especially like the ease of adjusting the area the flash covers.

[0.095 lb] I fell in love with this macro flash at my first use of it. The menu system is so intuitive and easy to make adjustments with. The flash exposes well, particularly with my Nikon D850. It works reasonably well with my Nikon Z 7 that had exposure problems with the little Nissin i400. The adjustments to change the power levels of the two tubes is quick and easy. It seems robust and I (hopefully) expect it to last well with use.
I use the MF18 with a Tamron 90mm VR macro lens and a Sigma 150mm OS/HSM macro lens - both work successfully with it.
