Sigma VF-41 External Optical Viewfinder

Serving as a faithful alternative to the Sigma dp2 Quattro's LCD screen, the VF-41 Viewfinder is an optical external finder that attaches to the camera via its hot shoe. It utilizes an Albada-type inverted Galilean design and incorporates a dedicated framing guide to match the camera's 30mm f/2.8 lens.
