MACRO or EXTENSION BELLOWS can best be likened to an extension tube set with variable extension. We do not currently sell bellows units, but are investigating the possibility of making a small unit. However, we can supply either from stock, or to order, adaptors to convert existing bellows units to take other cameras and lenses. Generally, a bayonet to bayonet adaptor can be expensive to produce for both the body and lens end of a bellows, and it is often less expensive for us to convert the bellows rather than use adaptors, or use ’piggy-back’ adaptors. We will need you to send us the bellows for examination if conversion is preferred so that we can give you a quotation. Some bellows (such as BPM or Helios), have interchangeable mounts and we have a limited range of body and lens mounts available
Converting an ‘old’ unit to ‘new’ fittings often provides a solution to the scarcity of
reasonably priced modern macro bellows systems.
