I have used Lee Gel Filters for years as I have not liked Cokin Filters.
Frankly, while on the subject of filters, I would like any information on the quality of Hoya Filters, please. When I started in photography we used Tiffen, B + W, Schott and Zeiss filters. Then Tiffen filters became sketchy in quality and lots of reported artifacts resulted. Today, there are few Schott and Zeiss filters available for cameras and Hoya Filters seem to have become ubiquitous. How is their quality

??
Thanks,
Tom
