I handled these lenses at New York's PhotoExpo. They are heavy lenses at 2460, 2320 and 2400 grams respectively. I'd say that if one shoots 11x14 or bigger, these lenses are must haves. I think that they are overkill for 8x10. I was told that list prices are over $10,000 each.
The coolest one was the 1100mm barrel lens. Its image circle wide open at f/14 is 900mm-the same as stopped down to f/22 . It comes with a fantastic set of waterhouse-type stops that slide into the barrel oh so smoothly-I want one.
I have a strong feeling that there will be a short run on these lenses, and they'll never be made again. IMHO, they will probably go up in value!
