I use diffuser material on mine at times. I purchased a couple yards of it for all the random uses I have for it when needed. I have 2 canon cameras set up with different lens which uses 2 different size adapters for my ring light. It comes off quickly and is interchangeable between cameras in less than a minute. I have had this ring light for almost a year now and have not had a bit of problem with it. I set up my images with the light on continuous and adjust camera settings with live view on my computer monitor...could use a better macro lens but this $50.00 Yongnuo YN 50mm F/1.8 EF AF / MF Prime Fixed Lens works for now. Always more to buy as money permits...
