This is a very nice camera filter from a reputable company. It is made of high quality optical glass with nanometer, multi-coating layers of ultra-thin and ultra-light materials. The frame is very light and small compared to the other filters I have for my camera.

This is a special effects filter primarily for portraits to soften the details of your subject. This is a 1/4 diffusion/mist filter and the changes from a normal, non-filtered lens, are minimal. K&F makes this same filter in lesser and greater strengths (i.e., 1/8, 1/2). So you have to decide what diffusion level you want for your specific studio shoot/setting. I thought 1/4 was a good place to start experimenting with this type of effect.

This filter also included 3 nice sized microfiber cleaning cloths. (It would have been nice if there were in a resealable/reusable bag though.) The price is very good considering you are getting a high-quality, multi-coated glass filter from a good company. In my different experimental shots, I think this filter has a lot of potential for portraits and still-life. I'm also wanting to try it out on macro shots.
