I'm selling my 12" Commercial Ektar in a working Ilex 4 shutter. The only significant fault you will find is the dent in the front filter ring from a previous owner. The glass coatings are in excellent shape, and the shutter sounds accurate. The T setting sometimes doesn't stay open (it obviously did for the photos), in which case it behaves like Bulb. No flange or retaining ring. I would like to net $200 from the sale. I can be reached at anthony dot karnezis at gmail. Thanks for looking.
