What's there to say about this? You know this is an asset in your camera bag. You won't find a negative comment about it unless one of those squirrely "it's too heavy" types complains about the #5 shutter. S. K. Grimes gave the shutter a CLA last summer, so all of the dried lubricant in the shutter from 1957-2010 is gone and replaced with something a little slicker and modern. It's ready for the next 50 years of use. It's got the mounting flange. It comes with both caps to help keep the glass in it's present condition. This lens in this condition doesn't come around often. Get it before I change my mind and keep it. $550 anywhere in the US, $575 anywhere else. Paypal preferred (gift or add 4% to cover fees) or postal money order accepted.
