## Description

Review: Excellent. - 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.
Review: Great Value - As far as I can tell, this filter rocks for my use-case. I wanted a weaker filter for low light. I have not used one for many years, however. Nothing to compare it to.
