This Fish Eye Lens Kit has all you need to get started in Fisheye experimentation for 35mm or Holga 120 (Medium Format) cameras. It includes the FEL-135 or FEL-120 Fisheye lens (based on option chosen) together with the FV-1 Fisheye Viewfinder, essential for composing those amazing images. The Fisheye lens is an extraordinarily wide angle lens that can produce amazing images with extreme distortions (especially so for macro/micro images). Please note the Holga camera shown in the product images in shown only for illustration and is not included.
