The #308 Adapter Ring Bay 3 Lens Size to 49mm Filter Size from Heliopan is a reliable and economical way to use filters. This ring will allow you to use 49mm filters on lenses with a Bay 3 front filter thread size.
Using this ring saves you money since you won't have to buy the same filter two times for two different sized lenses. A series of these reasonably-priced adapter rings is far less expensive than buying the same filter in two sizes.
Heliopan has been a leader in the photo/filter industry since 1949. They are known for their high- quality and production standards. Heliopan offers a full range of brass adapter rings that are renowned for the durability and reliability. Less expensive stepping rings have a tendency to "jam" or jump threads. However, Heliopan brass adapters screw on and off with greater ease and demonstrate less chance of damage.
