I recently bought a 3.5F in near mint condition so I decided to sell my 2.8E in excellent condition other than a few scrapes and brown spots on the leather. Glass, blades and focus all nice. I originally bought this a couple of years ago knowing it had slight separation on the front lens but the photos were always fine, but I ended up having the lens re-cemented and now it looks great. I also bought another 2.8E that needed a lot of work but I have it working enough that I can use it if I ever want the 2.8 aperture.
Price: $895 plus insured US shipping.
