Series 6 - Summitar
Series 6 - Summitar
A summitar A36 to series 6 adapter is the way to go. You can then get series 6 adapters for your other lenses and therefore only need one set of filters.
Bear in mind that older (tiffen) filters will consist of gel sandwiched between two pieces of glass, and will often be have some degree of defect because of this construction breaking down. Tiffen, and other less expensive filters, use what is called green glass, glass which in the process has not had the iron content removed. In addition, such filters are non usually coated or multi-coated. This means that they may cause image degradation by the bouncing around of light within the filter before the light enters the lens. The point here is that all of those large selections of cheap system x filters out there may not be usable anymore. Have to check each one you are intending on buying. Leitz/B+W/Heliopan typically use(d) dyed optical glass with (multi)coating. They are substantially more expensive. Most really necessary filters can be If special ordered from B & H; to know which one go to the B + W website and download their filter catalogue/manual. The last thing to bear in mind is that if you are planning to use more than one filter you have to worry about the filters vignetting. In order to avoid this, you can use a series 6 adapter with a series 6 filter in position one, then use a series 6 -series 7 adapter, then use series 7 filter for all subsequent filters. That way you are safe. If you think it through from the beginning, you will not be unpleasently surprised at the end.
