Kickstarter campaign seeks funding for Alter RFS, a hinged lens filter adapter
Alter has launched a Kickstarter funding campaign for Alter RFS, a Rapid Filter System that attaches lens filters to a camera via a hinged adapter. The Alter RFS friction hinge supports 270 degrees of rotation, enabling photographers to lower a filter over the lens when needed, then quickly lift it out of the way again. dpreview.com »
