I bought this for use on my 503CW, but due to failing eyesight sold the camera. I inserted it once to make sure it fit OK, but never used it.
I have 100% eBay rating over many, many years. I will ship this in the Continental US via USPS Priority Mail, usually 2 days.
It has the two notches on one side confirming it is a Acute Matte D focusing insert.
Asking $445 and I will pay the CONUS shipping. All others kindly inquire about shipping costs to Alaska and Hawaii.
I only ship to verifiable US Paypal addresses of record. Don't even think about asking for me to ship to another address.
