YONGNUOYN14EX II Macro Ring Flash for Canon DSLR Cameras, with Adapter Rings and Color Temperature Filters, Hot Shoe Mount, Support M, TTL Flash

Works perfect

Buen flash, muy buena calidad y funciona bien con la Canon 90D

Works perfectly with Canon R5 and Canon RF 100mm f2.8 Macro lens.My only gripe, and why I did not give it 5 stars is that the 67mm adapter, which is required for the Canon Macro lens has an inside diameter of 64 mm. There is no lens cap that fits this. Because this is used (by me) for insect photography, it is essential to keep the lens protected until ready to shoot. YONGNUO should have at least included a cap that fits the Canon Macro 67mm adapter as this is what it is billed for.For those who care, the flash duration goes from about 100 microseconds and up on ETTL to 1.05 milliseconds on manual. Rather interestingly, the light output for duration above about 100 microseconds is a flat-topped pulse, that is, constant light output during the flash, unlike a xenon flash tube flash.The attached photos were shot at f16, 1/200 second, ETTL, M camera mode, and about 15 cm from the front of the RF 100mm f2.8 Macro.

Los filtros que traen también son bastante útiles

I looked at few other units that cost less but decided to go with this one as I have other Yongnuo flashes and they all work great. This is a very nice unit and it does exactly what I want it to do. That's all I ask for.

I just got into macro photography 2 months ago. purchased the Canon 100mm Macro L. it takes amazing photos but I always need more light. I used my video lights at first, but it still wasn't giving me what I wanted. Here comes this amazing flash. It comes in a cool case, with gels, and lens adapters to fit most sizes. The build is a high quality plastic. The flash seems to work great. I like how you can control both sides to create a better looking image so it doesn't look flat. Save yourself $400 and get this bad boy instead of the canon version.

This is actually my second flash (newer version) from the same company. The first one worked well, but the battery compartment broke. This required taping it shut which worked for a time, but started getting annoying. Time for a new flash. It worked fine for a time, but within a year started having an issue where it would work intermittently. After taking one shot, the flash would not work on the second shot. Taking a couple more shots, the flash would start working. Sometimes it would require taking it off and putting it back on again. Tried it on another camera which also exhibited the same issues. After troubleshooting with support, I had cleaned the contacts, changed batteries and other suggestions. Ultimately, it got me nowhere. Support kept requesting more and more information which I had already provided and just got tired of dealing with them. Given the time zone difference, going back and forth and the late responses took weeks to troubleshoot with no resolution. If it worked consistently, this could be a great value but it did not work for me.

Wonderful product, came intact and ready to use
