I am selling this item because it doesn't fit the camera lens I purchased. Product Description 【Strobe Diffuser】 This product is ideal photographic lighting equipment. This softbox has a diffuser on the front, which generates uniform exposure and can switch the speedlight to a ring flash, producing a more wonderful lighting effect. Because the faces of each other are hidden, you can make a very natural expression. 【Diffusion Material Prevents Shadows】By using the diffuser, the light is evenly spread over the subject during shooting, effectively preventing shadows cast on the subject, providing more uniform and smooth light, and completely surrounding the lens to create shadow-free images. 【Applicable Locations】The circular flash diffuser is easier to catch light more accurately, creating a circular eye light in the subject's eyes, making the eyes look more beautiful. It is ideal for product photography, portrait photography, studio work, weddings, macro and portrait photography, and more. In addition, it can also be used as an emergency light! 【Easy Installation】Using the elastic band, the light softbox is foldable, making it easy to install and use, and easy to carry. It's a ring softbox that anyone can use, regardless of whether they are a photographer or a beginner.
