I was very surprised at how good the quality of this Haida filter. Delivered in a very good package convinced the filter for several reasons me: thread clean, runs perfectly and is smooth as silk on my lens. Processing acts (see what happens in the next few years time) very well. The photos are crisp and the minimum warm color shift is negligible for me. The filter I can with a clear conscience. 82 mm for the price: almost unbeatable.
