### ⭐⭐⭐⭐⭐ Review
*by I***M on 9 July 2025*

It's great. Really improves color (just be patient and rotate the filter carefully), gives much better (optical) result than image processors. You'd lose 1-1.5 F but worth it. Could even be very useful in darker environment where sporadic light sources are present. Not exactly cheap but good investment in thousand of photos. Shipping was fast. Thanks.
