Using this with a Fujifilm Xpro 3 on a 27mm lens, no compromise on quality. The diffusion is smooth and provides a great atmosphere to your shots. Definitely grabbing one for my 50mm lens.

How to: 101

1/2
Determine Filter Size
Match the diameter (e.g. Ø49mm) on your lens to the filter size. This is different to focal length.
2/2
