We recommend the Heliopan filter adapters, as these are stable and precisely made of brass. The adapters made of brass are mass-stable in temperature fluctuations and tilting not as fast as aluminum rings, which is particularly noticeable in large diameters positive. The reducing ring serves to secure a filter with a smaller thread diameter to a lens having a larger thread diameter. Please note that the reducing rings may occur to shadows or vignets.
