For Sale: A DAYI Panoramic Back for 4x5 cameras. Fits all 4x5 cameras with an international or Graflok back. I have used this on both a Chamonix 045N and a Shen Hao HZX II. It works well with wide angle lenses through about 180mm. Anything over 180mm and the camera body starts to shade the edges. Gives 4 exposures on 120 film. The back also has masks that can be installed for 6x12 and 6x9 operation. I have lost these masks, but I will post them when and if I can find them. I've seen them in the last 6 months, but probably filed them away for safe keeping. I have never used them since I was only interested in this for the 6x17 mode. Works perfectly. Has a few marks on the paint on the side facing the camera. Looks like adhesive residue. It's been on there since I bought it and doesn't cause an issue. Also is missing one screw in the upper left corner of the name plate. Again not causing any issues. Asking $460 shipped in the US. PayPal personal accepted, or we can split the Paypal fees if you want to use credit.
