I was amazed by this sale. (grin)
I always heard that Gray Levitt was a master at attracting well heeled buyers, buy this is quite something.
Considering that the 5.6 version was made in even smaller numbers, what would that fetch?
I have seen these go on ebay for USD 1000.
For your ease of mind, I have used a 6 2.8 and was impressed by the looks of the lens, but not with the picture-quality.
