Only 8 months old, This provides a convenient way to expand your range of lenses.The Converter attaches between the lens and body to increase the focal length by a factor of 1.7. The Converter 1.7 features the same outstanding optical and mechanical quality as all the lenses in the Hasselblad H system. I used it mainly with the 150 and 210mm lenses, with outstanding results. The shot with the climber is at 360mm, with the 210mm, handheld. As a jpeg it does not do justice to the original file. Will sell for $1000, best bang for the buck.
