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.

Alter RFS, which is made out of milled anodized aerospace aluminum, features a magnet for sealing the filter over the lens and a light shield for preventing light leaks. The adapter supports existing lens filters with universal threads and can be rotated to move the hinge to the ideal position for the user's needs (from the top to the side of the lens, for example).

The friction hinge prevents the filter from falling back down over the lens even during rough camera movements. Alter plans to offer the Rapid Filter System in filter sizes 40.5mm to 105mm, as well as an RFS+ adapter model that includes a built-in step-up.

Alter is offering Kickstarter backers various discounts for pledging funds to the campaign, with those discounts starting at $67 USD for a single Alter RFS up to $59 USD each for three units and $55 USD for any additional units beyond that. The company anticipates a retail price of $79 USD, assuming the campaign is successful and the product is brought to market. Shipments to backers are estimated to start in September.
