The product comes with excellent packaging, externally well-finished and internally the filter is housed in a practical transport case. In the package we find: - filter - filter cap - wrist strap - vacuum-packed microfiber cloth I will not dwell on the technical specifications since they are already widely mentioned in the product description but, I will tell you about my experience of use and impressions. As soon as we open the package we immediately notice how the product is of excellent workmanship both for what concerns the metal outside the filter and the filter itself which has an excellent multicoating already clearly visible to the naked eye before trying it with the shot, the cap is also of excellent workmanship, very solid and with the presence of an eyelet to be able to attach a strap which is supplied together with a vacuum-packed microfiber cloth. I tested the filter with a Samyang autofocus 35mm f2.8 and it performed really well, during the day I did not have any particular Lens effects, in night situations you have some Lens effects but only in certain conditions of light angles. The loss of detail is very low and imperceptible on APS-C sensors while slightly perceptible on full-frame sensors especially when we go to crop in post production. In conclusion it is an excellent product also rich in accessories, my final evaluation is 5 stars
