I purchased this flash through the Vine program, because I have a Lumix G7 camera with a very weak built-in flash, and another small Sony that doesn't even have a flash. This small flash behaves well in general, it recharges quickly between shots, both cameras make it jump right in the shoe. You have to manually choose the amount of light by adjusting the speed, trying to adjust it to that of the camera. For an amateur like me, this takes a while to learn, but it suits me very well. It lasts a long time charged, I haven't had to recharge it in two days of testing. It is very light and small in size, at the cost of being a little low in the camera and not being able to rotate (see what I have said about it in “drawbacks”). It has an auxiliary or filling flash mode that in theory detects the light of the main flash and makes it jump, but I haven't been able to make it work, I'll continue researching it. It comes with a cloth cover, fairly clear instructions and a diffuser. It does not come with a charger but it does have a USB C cable for the cell phone or similar. Disadvantages: -Logically, being fixed, it cannot be rotated upwards to bounce the light, it is not an inconvenience as such, but it must be taken into account. Fortunately, the plastic diffuser it comes with can soften the light. -The biggest drawback in my opinion is that being so low -which is good in general-, in the Sony it barely protrudes from the body and some lenses produce a shadow from the flash at the bottom of the image (see sample photo). It can be fixed with a “hot shoe” shoe adapter that raises it a little, but it's another element to add. For that reason I'm removing a star from it. -I haven't been able to synchronize it with another flash yet, but this is probably due to my inexperience with flashes. CONCLUSION: a perfect flash for beginners in the world of night or artistic photography, which will make us learn a lot and will improve our photos for a reasonable price. I recommend it.
