So this light is too small for a 77mm lens. Although they have an attachment that attaches to the lens, this is a somewhat bulky light source that takes up most of your field of view. (You can see an example of a photo with a ring). Smaller lenses, a few sizes smaller, like a 58, maybe a 62 or a little more. This will almost certainly work with any kit lens on something like the Canon T7i or similar cameras. Flash. Well, it "blinks," but what actually happens is the light goes on and then off. The synchronization speed is 1/100 second. This means it has quite a slow shutter speed and you might start to get some blur and the light doesn't really flash quickly for a split second but stays on for a long time compared to the flash. Okay, so there's a setting that lets you just leave the lights on. So this could be a good option for you too. Price! How can you beat the price? This is a great price for what it is. It has potential and can be very interesting in certain situations. I think I'll try the more expensive version if it fits my 77mm lens. If not, that thing can still be fun on my kit lens.
