I'll start by saying that this filter will stay on my Canon 24-70 forever and that I'm pleased and amazed at the effect it gives my photos. The filter comes in a hard case that already distinguishes it from low-end filters: it is convenient to use and has a non-slip part with different notches for more filter sizes. The construction is superb and you can immediately see from the layer applied to the surface which is a professional tool. If you shoot a bit like me to get an effect similar to the diffusion/glow, you've already tried things like petroleum jelly on the lens, pulled stockings on a filter, or different films. Here this filter is far from it. It has a sneaky effect and does NOT degrade the image. The edges remain sharp while the colors in the photo seem to fade slightly, returning the quality you had when using the film: really enjoyable! I bought it for photography in broad daylight, but certainly one of the best uses is with night lights, where you can better appreciate that spread of colors and brightness. Despite being a misused term, this filter gives an organic digital photo paste. I would like to note that it does not have a shameless and vulgar widespread effect, but it is visible without looking in the eyes. Highly recommended for videos too!
