Landschapsfotograaf Bart Heirweg heeft een review gepubliceerd over de filters van 84.5mm. Hij testte zowel de grijsverloopfilters als de kleurverloopfilters. Zijn review vind je hier. Zijn conclusie:
In my opinion 84.5mm Filters succeeded in building a decent product which offers good quality for a more than reasonable price. The filters are well built, nicely packaged and do not introduce any noticeable colour casts. Filters are indispensible in landscape photography and with both Lee and HiTech becoming extremely expensive; I think the 84.5mm filters will certainly become an attractive alternative for both amateur and more advanced photographers.
